What is unit rate?

A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

The distance Jack needs to cover is 60 miles.

The rate at which Jack closes the distance:

difference in speeds

=  80-60

=20 mph.

That's the rate at which Jack is closing that distance.

We have formula:

D=RT. , D=distance, R=rate, t= time

60 = 20t

divide both sides by 20, we get

60/20=t

t=3 hours.

Step-by-step explanation:

Therefore, the derivative of e^(sin(x)) * [tex]e^{x}[/tex] is [tex]e^{x}[/tex] * [tex]e^{sinx}[/tex]* (cos(x) + 1), which we have found from first principles using the product rule.

In mathematics, a derivative is a measure of how a function changes as its input changes. It is the rate at which the function is changing at a particular point.

More specifically, the derivative of a function f(x) at a point x0 is defined as the limit of the difference quotient (f(x) - f(x0)) / (x - x0) as x approaches x0, provided this limit exists. This limit is denoted by f'(x0), which is read as "f prime of x0".

Geometrically, the derivative of a function at a point represents the slope of the tangent line to the graph of the function at that point.

The concept of derivatives is essential in calculus and is used in many fields of science, engineering, economics, and finance. They are used to find rates of change, optimize functions, and model physical phenomena.

We can use the product rule of differentiation to find the derivative of [tex]e^{sinx}[/tex] * [tex]e^{x}[/tex]:

Let f(x) = [tex]e^{sinx}[/tex] and g(x) = [tex]e^{x}[/tex]then the product rule states that:

(f(x) * g(x))' = f(x)' * g(x) + f(x) * g(x)'

Now we find the derivatives of f(x) and g(x):

f(x) = [tex]e^{sinx}[/tex], so, f'(x) = cos(x) * e^(sin(x))

g(x) =[tex]e^{x}[/tex], so, g'(x) = [tex]e^{x}[/tex]

Therefore, the derivative of [tex]e^{sinx}[/tex] * [tex]e^{x}[/tex]is:

(f(x) * g(x))' = [tex]e^{sinx}[/tex] * [tex]e^{x}[/tex])'

= f'(x) * g(x) + f(x) * g'(x)

= cos(x) * [tex]e^{sinx}[/tex] * [tex]e^{x}[/tex] + [tex]e^{sinx}[/tex] * [tex]e^{x}[/tex]

Simplifying this expression gives:

([tex]e^{sinx}[/tex]) * [tex]e^{x}[/tex])' = [tex]e^{x}[/tex] * [tex]e^{sinx}[/tex]* (cos(x) + 1)

Answer:

o find the x-intercept, we set y = 0 and solve for x:

3x + 6(0) = 6

3x = 6

x = 2

So the x-intercept is (2, 0).

To find the y-intercept, we set x = 0 and solve for y:

3(0) + 6y = 6

6y = 6

y = 1

So the y-intercept is (0, 1).

Answer: D.All interior angles are 90 degrees

The answer of the given question is (a)  Joseph would pay approximately $646.56 in interest over nine months. (b) Joseph would pay approximately $200.34 more in interest than Andres over nine months due to his lower credit worthiness.

An interest rate is the percentage at which a lender charges a borrower for the use of money or other assets. It is essentially cost of borrowing money. The interest rate is usually expressed as an annual percentage of the amount borrowed or invested, and can be fixed or variable depending on the terms of the loan or investment.

(a) Assuming Joseph receives the highest interest rate of 25.74%, the interest he would pay in nine months with an average monthly balance of $3,350 can be calculated as follows:

Interest rate per month = (25.74% / 12) = 0.02145

Average monthly balance = $3,350

Interest paid per month = (0.02145 x $3,350) = $71.84

Interest paid in nine months = ($71.84 x 9) = $646.56

Therefore, Joseph would pay approximately $646.56 in interest over nine months.

And assuming Andres receives the lowest interest rate of 17.74%, the interest he would pay in nine months with an average balance of $3,350 can be calculated as follows:

Interest rate per month = (17.74% / 12) = 0.0148

Average monthly balance = $3,350

Interest paid per month = (0.0148 x $3,350) = $49.58

Interest paid in nine months = ($49.58 x 9) = $446.22

Therefore, Andres would pay approximately $446.22 in interest over nine months.

(b) The difference in interest paid by Andres and Joseph can be calculated as follows:

Interest paid by Joseph - Interest paid by Andres = $646.56 - $446.22 = $200.34

Therefore, Joseph would pay approximately $200.34 more in interest than Andres over nine months due to his lower credit worthiness.

Using triangle proportionality [tex]\frac{AB}{AD}[/tex] is proportional to [tex]\frac{EC}{DC}[/tex]. Using the isosceles triangle in the construction EC = BC. These lead to the proportion that corresponds to the angle bisector theorem of  [tex]\frac{AB}{BC}= \frac{AD}{DC}[/tex].

The Angle Bisector Theorem states that a line bisecting an angle in a triangle divides the opposite side into segments proportional to the other two sides of the triangle. More specifically, if a line segment bisects an angle of a triangle, it divides the opposite side into two segments that are proportional to the lengths of the other two sides of the triangle.

In mathematical terms, let ABC be a triangle with angle bisector AD, where D lies on BC. Then, according to the Angle Bisector Theorem:

AB/BD = AC/CD

Here, the length of the line segment AD bisects the angle ∠A and divides the side BC into two segments BD and CD. The theorem tells us that the ratio of the length of side AB to the length of BD is equal to the ratio of the length of side AC to the length of CD.

Step-by-step explanation:i did this quizzie before

The sale price of $15.88 is a discount of 19.9% off the original price of $19.8. The percent of the discount on the blanket is 19.9%.

To find the percent of the discount on the blanket, we need to calculate the amount of the discount first.

The discount is the difference between the original price and the sale price:

Discount = Original price - Sale price

Discount = $19.85 - $15.88

Discount = $3.97

So the discount on the blanket is $3.97.

To find the percent of the discount, we can use the following formula:

Percent discount = (Discount / Original price) x 100%

Substituting the values we know:

Percent discount = ($3.97 / $19.85) x 100%

Percent discount = 0.199 x 100%

Percent discount = 19.9%

Therefore, the percent of the discount on the blanket is 19.9%.

The answer of the given question based on the equation to find arc the answer is 25.

In geometry, an arc is segment of curve, typically  portion of  circumference of circle. An arc is defined by two endpoints and  curve between them, and is measured by its central angle, which is the angle formed by two radii drawn to endpoints of  arc.

Therefore, we can find the measure of angle D as follows:

D=180 -70 -60=50

Now, we can set up an equation using the fact that the angle subtended by an arc at the center of a circle is twice the angle is subtended by  same arc at any point on  circumference of  circle:

2x = 360 - 70 - 50 = 240

If he agrees to pay back the loan in 8 yearly payments at 14% p.a. compound interest. The amount of each yearly payment is  K 368.51.

What does compound interest mean ?

When you earn interest on your interest earnings as well as the money you have saved, this is known as compound interest. For instance, if you deposit $1,000 in an account that offers 1% yearly interest, after a year you would have received $10 in interest.

                                    Compound interest allows you to earn 1 percent on $1,010 in Year Two, which equates to $10.10 in interest payments for the year. This is possible because interest is added to the principal in Year Two.

we have:

r = 14% = 0.14

n = 8

PV = K 2 000

We can solve for A by rearranging the formula:

A = PV * r / [(1 - (1 + r)^-n)]

Substituting the values, we get:

A = K 2 000 * 0.14 / [(1 - (1 + 0.14)^-8)]

A = K 2 000 * 0.14 / 0.7598

A = K 368.51

Therefore, the amount of each yearly payment that Mr. Apo Man needs to make to repay the loan in 8 years at 14% p.a. compound interest is K 368.51.

y - intercept of (-4,2) (6,-3) is (0,0)

Answer:

y = -4

Step-by-step explanation:

We are given two points (-4,2) and (6,-3). In order to find the y intercept, we we need to calculate the slope between the two points first. We can use this using [tex]\frac{y2-y1}{x2-x1}[/tex], which is how we can calculate the slope of a line.

[tex]\frac{-3-2}{6-(-4)}[/tex]

Evaluate

[tex]\frac{-5}{10} = -\frac{1}{2}[/tex]

Now that we found the slope of the line, we now need to plug in all of our information into the point slope formula and get it in slope intercept form.

[tex]y-2=-\frac{1}{2}(x+4)[/tex]

Distribute the negative half

[tex]y-2=-\frac{1}{2}x-2[/tex]

Add 2 to both sides

[tex]y=-\frac{1}{2}x-4[/tex]

The y intercept is -4.

In the scenario described, the standard deviation would be 2.74.

A measurement of a data set's deviation from the mean is referred to as "standard deviation".

Whereas a high standard deviation indicates that the data are more spread, a low standard deviation suggests that the data are clustered around the mean.

It displays the standard deviation of each score with respect to the mean.

A high standard deviation in a normal distribution indicates that values are frequently outside of the mean, whereas a low standard deviation indicates that values are clustered closely around the mean.

The standard deviation formula is as follows:

standard deviation = √np(1-p)

Assuming that p = 0.75 and n = 40, the following is the standard deviation:

standard deviation = √np(1-p)

standard deviation = √(40)(0.75)(1-0.75)

standard deviation = 2.74

Therefore, in the scenario described, the standard deviation would be 2.74.
