Answers

Answer 1

Answer: [tex]\$29.7[/tex]

Step-by-step explanation:

Given

The trophy has a side of [tex]a=9\ in.[/tex]

Slant height [tex]l=11\ in.[/tex]

Rate  of painting [tex]r=\$\ 0.15/in.^2[/tex]

Lateral surface area of square pyramid is [tex]2al[/tex]

Insert the values

[tex]\Rightarrow 2\times 9\times 11\\\Rightarrow 198\ in.^2[/tex]

Cost of painting

[tex]\Rightarrow 198\times 0.15=\$29.7[/tex]

find f(3) for the polynomial function F(x)=x^3-9x^2+5x-2

Answers

Answer:

f(3) = -41

Step-by-step explanation:

f(x) = x³-9x²+5x-2

now,

f(3) = 3³-9×(3)²+5×3-2

= 27-9×9+5×3-2

= 27-81+15-2

= -41

solve the inequality 3/5x +30>150

Answers

Answer:

Step-by-step explanation:

3/5x+30=150

We move all terms to the left:

3/5x+30-(150)=0

Domain of the equation: 5x!=0

x!=0/5

x!=0

x∈R

We add all the numbers together, and all the variables

3/5x-120=0

We multiply all the terms by the denominator

-120*5x+3=0

Wy multiply elements

-600x+3=0

We move all terms containing x to the left, all other terms to the right

-600x=-3

x=-3/-600

x=1/200

Survey data involving two random samples of students at law school are shown. The surveys were taken, comparing the age of students in 1900 to the age of students in 2014.

The statements that are true about the two samples of students:

In 1990, there was a 10-year age difference between the oldest and youngest students.In 2014, the median age of students was greater than the median age in 1990.

Thus, statement first there was a ten-year age gap between the oldest and youngest students in 1990.and statement fourth are correct

A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. He subdivided a portion of his land into 10 separate, but essentially equal, plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Below is a computer output for linear regression of amount of fertilizer versus yield for the 10 plots of land.

Predictor Coef SE Coef T P
Constant 10.100 0.7973 12.67 0.000
Fertizer 1.50 0.1879 6.12 0.000

What is the equation of the least squares regression line from this sample?

Answers

Answer:

Y = 10.1 + 1.50x

Step-by-step explanation:

From the data contained in the computer output for linear regression

The coefficient of intercept = 10.1

coefficient of fertilizer = 1.50

Sample of an Equation of least squares regression line

y = a + bx

where : a = intercept , b = slope

hence the required equation will be

Y = 10.1 + 1.50x

y = yield , x = fertilizer

Answer:

I=4 (Slant height)

R=3 (Radius)

H=5 (slant height)

Step-by-step explanation:

Imagine inclination, peprendicular height and radius as a triangle, so this will have a 90 degrees angle and Pythagor theorem will imply to the calculations, as :

[tex]a^{2}+b^{2}= c^{2}\\[/tex]

where Height is A , Radius is B, and Inclination is C we have:

What is the area of the figure composed of a parallelogram, a square, and a rectangle?

Answers

Answer:

Let's cut the figure into:

Parallelogram, square, and rectangle.

Let's find the area of the parallelogram first:

10 x 3.5 = 35

Let's find the area of the square:

4 x 4 = 16

When given one length of a square you already know are sides and lengths are equal so therefore 1 given length of a square is all the lengths.

Let's find the area of a rectangle:

6 x 12.5 = 75

Now let's add all the areas up:

35 + 16 + 75 = 126 square inches is your answer.
