Answer:

h(13) = 3

h(25) = 7

h(34) = 10

Step-by-step explanation:

In this situation, you plug in the number inside h, replacing t because the original function is h(t).

So,

h(13) = (13-4)/3

9/3 = 3

h(25) = (25-4)/3

21/3 = 7

h(34) = (34-4)/3

30/3 = 10

If we change the symbols, the system will have one solution.

x ≥ 2

x ≤ 2

Where the solution is x = 2.

Here we have the system of inequalities:

x > 2

x < 2

So, x can be smaller than 2 or larger than 2. Is easy to see that there are no values of x that are solutions of both inequalities, but if we replace both symbols by ≤ and ≥, then x = 2 will be a solution of both inequalities, and thus, a solution of the system.

x ≥ 2

Step-by-step explanation:

Kapitan Tiago borrowed 560,000 × 60 % = 336,000 from the bank.

To find the amount borrowed, we multiply the balance Kapitan Tiago paid in cash by the loan percentage he obtained. The loan percentage is expressed as a decimal, so we multiply 560,000 by 0.6 to get 336,000.

This means Kapitan Tiago borrowed 336,000 from the bank and paid

560,000 - 336,000 = 224,000     in cash.

The total amount he spent on the car is

336,000 + 224,000 = 560,000.

The equation of line J that is perpendicular to line K is: 3. y = 1/2x + 6.

Perpendicular lines have slopes that are negative reciprocals to each other, that is, if the slope of one is 3, the other will be -1/3.

Given that the slope of line K is -2, the slope of line J that is perpendicular to line K would be 1/2.

Substitute m = 1/2 and (x, y) = (6, 9) into y = mx + b to find b:

You were on the right track, I totally understand why you'd get stuck where you are currently in the process. To start with, you technically found the wrong ratio between the two triangles. Your ratio is just 2x, while it should be 2x/5.

To start, let's find the ratio between triangle FEG and ABC by dividing angle F by and A:

[tex]R=\frac{2x}{5}[/tex]

Now, multiply angle B by this ratio:

[tex](x+4)(\frac{2x}{5} )=\frac{2x^2}{5}+\frac{8x}{5}=\frac{2x^2+8x}{5}[/tex]

We can now set this expression equal to angle E, as we have multiplied by the common ratio:

[tex]\frac{2x^2+8x}{5} =18[/tex]

This looks rather daunting, but let's keep calm... you can do this!!

Start by subtracting 18 from both sides:

[tex]\frac{2x^2+8x}{5}-18=0[/tex]

Now, let's get the whole expression under the denominator 5:

[tex]\frac{2x^2+8x-90}{5}=0[/tex]

Notice that the denominator can now be removed:

[tex]2x^2+8x-90=0[/tex]

Now, factor the equation (you could also use the quadratic eq if you want)

[tex]2(x-5)(x+9)=0[/tex]

Notice that we have two potential values for x (5 and -9).

Think about this logically... If we use -9 and plug it in for x, we will end up with values of -5 degrees for an angle, which is impossible! Therefore 5 is the only valid answer!

I encourage you to also approach the problem from a different angle and use the common factor (5/2x) and multiply it by 18 :)

R-squared is calculated as the square of the linear correlation coefficient (r). In this case, the linear correlation coefficient is 0.817, so the R-squared can be calculated as follows:

R-squared = r^2 = 0.817^2 = 0.67

R-squared measures the proportion of variation in the dependent variable that is explained by the independent variable in a regression analysis. A value of R-squared close to 1 indicates that a large proportion of the variation in the dependent variable is explained by the independent variable, while a value close to 0 indicates the opposite.

In this case, a value of 0.67 for R-squared indicates that 67% of the variation in the dependent variable is explained by the independent variable, while the remaining 33% is unexplained.

The value of tan 5pi/12 in decimal is 3.732050807. . .. Tan 5pi/12 can also be expressed using the equivalent of the given angle (5pi/12) in degrees (75°).

We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/pi)

⇒ 5pi/12 radians = 5pi/12 × (180°/pi) = 75° or 75 degrees

∴ tan 5pi/12 = tan 5π/12 = tan(75°) = 2 + √3 or 3.7320508

p(x) must be equal to (x-a)(x-b) where b is another number.

If p(a) = 0, then this implies that (x-a) is a factor of p(x). Therefore, p(x) can be factored into (x-a)q(x), where q(x) is a polynomial of degree one less than the degree of p. This means that p(x) must be equal to (x-a)(x-b) for some other number b. It does not mean that p(x) must be equal to the zero polynomial or (x-a)².

The product of two factors, (x-a) and (x-b), is a polynomial of degree two, p(x). This can be expressed in expanded form as p(x) = x² - (a + b)x + ab, where a and b are any two numbers

129 students had a private scholarship.

Out of the 843 students,

To calculate the total number of students with a private scholarship, we need to add the number of students who had a private scholarship (112) and the number of students who had both scholarships (17). This gives us a total of 129 students with a private scholarship. The rest of the students, who had either a government scholarship (80) or no scholarship (651), do not have a private scholarship.

209 students had only one of the two scholarships, so 209 - 129 = 80 students had a government scholarship.

So in total, 112 + 80 = 192 students had either a private or a government scholarship.

Therefore, 843 - 192 = 651 students did not have either a private or a government scholarship.

Answer:

Step-by-step explanation:

There are 16 ounces in 1 pound. Take 3/4 and multiply it by 16.

3/4 x 16 ounces = 12 ounces

There are 12 ounces in 3/4 lb.

The chef uses 1/8 of the 12 ounces (or 3/4 lb) of cheese for the top of the lasagna.

1/8 of 12 ounces

1/8 x 12 ounces = 1.5 ounces

The chef uses 1.5 ounces for the top of the lasagna.

To convert the ounces to pounds, use 1 lb/16 ounces. The ounces cancel and you are left with pounds.

1.5 ounces x (1 lb/16 ounces) = 0.09375 lb

When we draw tangents to the curve, we can see that if the gradient of the tangent is positive, the function is rising, and if the gradient is negative, the function is dropping.

The given figure  Y is the graphs only increase when x = 0.

Let's look at each graph individually.

When x0, graph W really decreases, therefore it is erroneous.

Because graph X grows when x0 but not when x0, it is a plausible explanation.
