Help!!! Quick answer please!

Answer:

30 foot by 20 foot

Step-by-step explanation:

1 inch = 10 inch

2 foot = d foot

Cross products: 1xd=2x10

d=20foot

1 inch = 15 inch

2 foot = d foot

Cross products: 1xd=2x15

d=30foot

Answer:

[tex]0.64 \pm 1.645\sqrt{\frac{0.64*0.36}{50}}[/tex], option D

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

From a random sample of 50 students, she found that 32 students read at least 1 book last month.

This means that [tex]n = 50, \pi = \frac{32}{50} = 0.64[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

Confidence interval:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.64 \pm 1.645\sqrt{\frac{0.64*0.36}{50}}[/tex]

So the correct answer is given by option D.

Answer:

[tex]f(8) = 81[/tex]

[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]

Step-by-step explanation:

Solving (a):

[tex]f(x) = x^2 + 2x +1[/tex]

[tex]g(x) = x - 5[/tex]

Solve for f(8)

We have:

[tex]f(x) = x^2 + 2x +1[/tex]

Substitute 8 for x

[tex]f(8) = 8^2 + 2*8 +1[/tex]

Solve

[tex]f(8) = 64 + 16 +1[/tex]

[tex]f(8) = 81[/tex]

Solving (b):

[tex](g\ o\ f)(x)[/tex]

This is solved by:

[tex](g\ o\ f)(x) = g(f(x))[/tex]

So, we have:

[tex]g(x) = x - 5[/tex]

[tex]g(f(x)) = f(x) - 5[/tex]

Substitute: [tex]f(x) = x^2 + 2x +1[/tex]

[tex]g(f(x)) = x^2 + 2x + 1 - 5[/tex]

[tex]g(f(x)) = x^2 + 2x -4[/tex]

Hence:

[tex](g\ o\ f)(x) = x^2 + 2x -4[/tex]

Answer:

m(arc FE) = 166°

Step-by-step explanation:

By theorem of intersecting chords and tangent of a circle,

Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.

m(∠GFE) = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]

83° = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]

m(arc FE) = 166°

Answer:

$2,800

Step-by-step explanation:

The formula for simple interest is I = PRT, where I is the interest (earned or paid), P is the principal amount invested/borrowed, R is the rate in decimal form, and T is the time in years.

I = (2000)(0.05)(8)

I = $800

Then we add that to the principal to get $2,800

---------------------------------

Joey made a deposit into an account that earns 6% simple interest. After 3 years, Joey earned $400. How much was Joey's initial deposit?

I = PRT

400 = P(0.06)(3)

400 = 0.18P

P = $2,222. 22

----------------------------------------

Peter is calculating the interest earned on a deposit of $275 in an account that earns 8% simple interest after 12 years. What is the ??? guessing interest earned?

I = PRT

I = (275)(0.08)(12)

I = $264

------------------------------------

Neil's grandmother has left him a small inheritance of $6,000. Neil would like to invest it at a rate of 5% interest. What is the simple???

I = PRT

I = (6000)(0.05)(T)

Answer/Step-by-step explanation:

The triangle given is a right triangle

Reference angle = angle E

Thus:

The side that is opposite to angle E is side DF = e

The side that is adjacent to angle E is side EF = d

The hypotenuse side is the longest side that is opposite go the right angle of the triangle = DE = f

Answer:

  √29

Step-by-step explanation:

We can call the given points A(3, 4) and B(-2, 6).

The right triangle with segment AB as a hypotenuse can best be drawn along grid lines. Then the vertical leg is the difference of y-coordinates: 6-4 = 2, and the horizontal leg is the difference of x-coordinates: 3 -(-2) = 5.

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs.

  AB² = 2² + 5²

  AB² = 4 + 25 = 29

Taking the square root, we find the length of the line segment between the points to be ...

  AB = √29
