The base of a triangle exceeds the height by 3 yards. If the area is 65 square yards, find the length of the base and the height of the triangle.

Answers

Answer 1

The length of the base is 13 yards and the height of the triangle is 10 yards.

Let h = ht of the triangle

let (h + 3) = base of triangle

A = (1/2)bh is the formula for the area of a triangle

65 = (1/2) (h + 3)h

130 = [tex]h^2[/tex] + 3h

[tex]h^2[/tex] + 3h - 130 = 0

(h + 13)(h - 10) = 0

h = -13, h = 10

Height = 10 yards, base = 13 yards

Answers

The constant of proportionality is 12

Number of fresh jars of honey stored by The Busy Bee in 3 hours= 36 jars

Number of fresh jars of honey stored by The Busy Bee in 7 hours= 84 jars

So, In 3 hours = 36 jars

In 1 hour = 36/3 = 12 jars

Similarly, In 7 hours = 84 jars

In 1 hour = 84/7 = 12 jars

Answers

The quadratic function is expressed as

f(x) = - x^2 + 10x - 22

The y intercept is the value of y or f(x) when x = 0

Thus, to find the y intercept, we would substitute x = 0 into the function. Thus, we have

f(0) = - 0^2 + 10 * 0 - 22

f(0) = 0 + 0 - 22

f(0) = - 22

Thus, the y intercept of the function f is (0, - 22)

Answers

Water :60 ounces

Salt solution:60 ounces

Explanation

Step 1

set the equations

Let x represent the amoun of water forthe solution

let y represents the amount of solution ( 40% salt)

so

a)the scientific mixes water with the solution to obtain 120 ounces, so

[tex]x+y=120\Rightarrow equation\left(1\right)[/tex]

b)the mixture is 20% salt

so

salt fromwater+salt from solution( 40%) = salt in the solution (20%)

so

[tex]\begin{gathered} 0+0.4y=120*0.2 \\ 0.4y=24 \\ divide\text{ both sides by 0.4} \\ \frac{0.4y}{0.4}=\frac{24}{0.4} \\ y=60 \end{gathered}[/tex]

hence, the amount of salt solution is 60 ounces

,now to find x, replace the y value in equation (1)

[tex]\begin{gathered} x+y=120\Rightarrow equation\left(1\right) \\ x+60=120 \\ subtract\text{ 60 in both sides} \\ x+60-60=120-60 \\ x=60 \end{gathered}[/tex]

so, water : 60 ounces

therefore, the answer is

Water :60 ounces

Salt solution:60 ounces

Find the points on
y = x³ + 6x² - 15x + 1 at which the
gradient is zero.

Answers

Answer:

(-5, 101) or (1, -7)

Step-by-step explanation:

The gradient of a function is zero when its first differential is zero

Taking first derivative of y = x³ + 6x² - 15x + 1

we get
[tex]\dfrac{dy}{dx} = \dfrac{d}{dx}(x^3+6x^2-15x\:+\:1)[/tex]

[tex]= \dfrac{d}{dx}(x^3)+ \dfrac{d}{dx}(6x^2) - \dfrac{d}{dx}(15x)\:+\: \dfrac{d}{dx}(1)\\\\[/tex]

[tex]= 3x^2 + 2(6x) - 15 + 0\\\\\\= 3x^2 + 12x - 15x\\[/tex]

Set this first differential to 0, find the solution set for x

[tex]3x^2 + 12x - 15x =0[/tex]

This is a quadratic equation which will have 2 solutions for x.

First divide throughout by 3
[tex]= > x^2 + 4x - 5 = 0[/tex]

Factor the term:
[tex]= > x^2 + 4x - 5 = 0\\\\== > (x -1)(x + 5) = 0\\== > x - 1 =0 \text { or } x + 5 =0\\\\[/tex]

This means x = 1 or x = -5 is the solution set

To find the y value corresponding to these values of x, plug in each of these x values in the original equation and solve for y

Plug in x = 1 into equation x³ + 6x² - 15x + 1

=> 1³ + 6(1)² - 15(1) + 1

=> 1 + 6 - 15 + 1

=> -7

So one point is (1, -7)

Looking at the choices we can eliminate the first and  last choices

Looking at choices 2 and 3 we see that only one of them has x = -5 which is the other solution value. This is the second choice

So the correct answer is second choice
(-5, 101) or (1, -7)

Note we did not have to go through the pain of computing y for x = -5


Find the area of the figure given to the right. The hexagon is regular. Round to the nearest whole number.

a wildfire organization wants to fence off an area of a beach. The organization can only fence 100 yd². what length (x) and width (y) should the organization use the Least amount of fencing as possible

Answers

It is given that the total area of the beach is 100 yd².

We have to find the length x and the width y that the organization shoul use to use the least amount of fencing as possible. it means that we have to find the dimensions for which parameter is leasr.

The perimeter of a rectangle is:

[tex]P=2\times(l+w)[/tex]

In option 1, the length is 50 yards and the width is 20 yards. then the perimeter will be (using the previous formula) equal to 140.

In option too the perimeter will be 130.

in option 3 the perimeter will be 134.44

and, in option 4 it will be 146.36

therefore the least perimeter is 130 when the length is 40 yd and the width is 25 yd.

For a normal distribution, it is known that the mean is zero and the standard deviation is 1. Be sure to draw and label a normal distribution for each problem. Find the probability that a z score is between -1.15 and 1.98.

Answers

To find the probability between two z-scores on a normal distribution, we can use a z-score table.

A z-score table gives the probability of a data less than the corresponding z-score, like in the picture:

So, if we want the probability between 1.98 and -1.15, we need to do the following:

[tex]P(-1.15However, usually z-score tables go only from z = 0 and above, so we need a way to consult the negative z.

Since the normal distribution in symmetric around z = 0, we have that:

[tex]P(z<-1.15)=P(z>1.15)[/tex]

And since the whole distribution give a 100% probability, or an area of 1, we have that:

[tex]\begin{gathered} P(z<1.15)+P(z>1.15)=1 \\ P(z>1.15)=1-P\mleft(z<1.15\mright) \end{gathered}[/tex]

So, in the end, we have:

[tex]\begin{gathered} P(-1.151.15) \\ P(-1.15So, we can consult the values for the probabilities of z < 1.98 and z < 1.15 on the z-score table:[tex]\begin{gathered} P(z<1.98)\approx0.9761 \\ P(z<1.15)\approx0.8749 \end{gathered}[/tex]

So, the total probability is:

[tex]\begin{gathered} P(-1.15So, the probability is approximately 0.8510.

Write an equation of the line passing through (4,-2) that is parallel to the line -3x minus 4y =5

Answers

Answer:

Step-by-step explanation:

y=4x3

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

First, rearrange -3x - 4y = 5 into y = mx + c form.

-3x - 4y = 5

-4y = 3x + 5

y = -3/4x - 5/4

Since parallel lines have the same gradient, equation of line is y = -3/4x + c.

Substitute (4,-2) into the equation to find c.

-2 = -3/4(4) + c

c = 1

Hence, equation of line is y = -3/4x + 1.

Think about what is different here? What makes this a challenge? Can you use skills you already know to figure out the intercepts here?

Answers

We are given the following line equation:

[tex]4x+5y=20[/tex]

We are asked to determine the x and y-intercepts of the line. To do that, we will convert the given equation into the following form:

[tex]\frac{x}{a}+\frac{y}{b}=1[/tex]

Written in that form the value of "a" is the x-intercept and the value of "b" is the y-intercept. Therefore, we need to divide the given equation by 20 in order to get a 1 on the right side:

[tex]\frac{4x}{20}+\frac{5y}{20}=\frac{20}{20}[/tex]

Simplifying we get:

[tex]\frac{x}{5}+\frac{y}{4}=1[/tex]

Therefore, the y-intercept is 4 and the x-intercept is 5.

Write an equation in slope - intercept form for the line that passes through the given paint andis parallel to the given equation.4.(-4, 2), y = -1/2x+ 6

When two equation are parallel it means they have the same slope.

You can identify the slope(m) as the number next to the x in equation that follow the next form:

[tex]y=mx+b[/tex]

Then, the equation parallel to the given equation has an slope of:

m= - 1/2

Now, if we have a point of the equation we can find the value of the b (y-intercept) in the slope - intercept form of a lineal equation:

[tex]y=mx+b[/tex]

The given point is ( -4 , 2)

You have the next values:

m= - 1/2

y= 2

x= -4

Then we substitute that values:

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

And clear the b:

[tex]2=\frac{4}{2}+b[/tex][tex]2=2+b[/tex][tex]2-2=2-2+b[/tex][tex]0=b[/tex]

Now, we get the value of the slope (m= - 1/2) and the y-intercept (b=0)

We can write the equation in slope - intercept form:

[tex]y=-\frac{1}{2}x+0[/tex]

[tex]\implies 3^{-16} \cdot 2^{10} \cdot \dfrac{2^{(-2 \cdot 4)}}{3^{(3\cdot 4)}} \cdot 3^{28}[/tex]

[tex]\implies 3^{-16} \cdot 2^{10} \cdot \dfrac{2^{-8}}{3^{12}} \cdot 3^{28}[/tex]

[tex]\textsf{Apply the exponent rule} \quad \dfrac{1}{a^n}=a^{-n}[/tex]

[tex]\implies 3^{-16} \cdot 2^{10} \cdot 2^{-8} \cdot 3^{-12} \cdot 3^{28}[/tex]

Gather like terms:

[tex]\implies 2^{10} \cdot 2^{-8} \cdot3^{-16} \cdot 3^{-12} \cdot 3^{28}[/tex]

[tex]\textsf{Apply the exponent rule} \quad a^b \cdot a^c=a^{b+c}:[/tex]

[tex]\implies 2^{(10-8)}\cdot3^{(-16-12+28)}[/tex]

[tex]\implies 2^{2}\cdot3^{0}[/tex]

Any number to the power of zero is 1:

[tex]\implies 2^{2}\cdot 1[/tex]

[tex]\implies 2^2[/tex]

Therefore, the solution is:

[tex]\implies 2^2=2 \times 2=4[/tex]
