Answer:

A. tan 38° = opposite/adjacent

opposite = (tan 38°)(adjacent)

opposite = (0.31)(17 ft)

opposite = 5.27 ft

B. height is = 5.27 ft

The models the height of the building is y = 17 tanθ and if θ=38° then the height is 13.28 feet

A mathematical model is a linguistic and mathematical concepts-based description of a system. Mathematic modeling is the process of creating a mathematical model.

(A) Give the building and is shadow is 17 feet and make θ.

then the relation is tanθ =y/17

So y = 17 tanθ

(B) If the is angle is 38°

then

tan38° =y/17

0.7813 = y/17

        y = 13.28 feet

Hence the model is tanθ and when the angle is 38° the value of y is 13.28 feet.

Answer:

c = 6.4

Step-by-step explanation:

Answer:

Surface Area = (2 • π • r²) + (2 • π • r • height)

Surface Area = 2 * 3.14 * 3*3 + 2 * 3.14 * 3 * 15

Surface Area = 56.52 +  282.60

Surface Area = 339.12

Answer:

(a): 6. (b): 4. (c). Bob's sample, as it has a larger sample size.

Answer:

The 95% confidence interval for the mean of gas mileage for this vehicle is (S - 1.53, S + 1.53), in which S is the mean of the sample of 20.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96\frac{3.5}{\sqrt{20}} = 1.53[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is S - 1.53.

The upper end of the interval is the sample mean added to M. So it is S + 1.53.

The 95% confidence interval for the mean of gas mileage for this vehicle is (S - 1.53, S + 1.53), in which S is the mean of the sample of 20.

Answer:

15 cm

Answer:

1.05

Step-by-step explanation:

Answer: $1.05

Step-by-step explanation:

I think this answer is correct because, all we have to do here is divide 4.20 by 4 (because there is 4 friends and they each get an equal amount.) So 4.20 divided by 4 equals 1.05.

Answer:

Coordinates of point R = (6,5)

Step-by-step explanation:

Given;

Point A(2 , 1)

Q(-4 , -5)

m1:m2 = 3 : 2

Find:

Coordinates of point R

Computation:

X = [(m1)(x2) + (m2)(x1)] / (m1 + m2)

2 = [(3)(x2) + (2)(-4)] / (3 + 2)

2 = [3x2 - 8] / (5)

10 = [3x2 - 8]

3x2 = 18

x2 = 6

Y = [(m1)(y2) + (m2)(y1)] / (m1 + m2)

1 = [(3)(y2) + (2)(-5)] / (3 + 2)

1 = [3x2 - 10] / (5)

5 = [3x2 - 10]

3y2 = 15

y2 = 5

Coordinates of point R = (6,5)

Answer:

4% of the tested population scored higher than Randy on the test

Step-by-step explanation:

P(X>105) = normalcdf(105,1e99,94,6.2) = 0.0380155219 ≈ 0.038 ≈ 3.8% ≈ 4%

Therefore, about 4% of the tested population scored higher than Randy on the test.

Answer: 3

Step-by-step explanation:

Answer:

(rx)(4) = 8

Step-by-step explanation:

Given that,

[tex]r(x)=2\sqrt{x}[/tex]

and

[tex]s(x)=\sqrt{x}[/tex]

We need to find the value of (rs)(4).

[tex](rs)=2\sqrt x \times \sqrt x\\\\=2\times (\sqrt x)^2\\\\=2x[/tex]

[tex](rs)=2x\\\\=2\times 4\\\\=8[/tex]

So, the value of (rx)(4) is equal to 8.

Answer:

(x + 3)² + (y - 4)² = 32

Step-by-step explanation:

Since we are given the coordinates of the centre and a point on the circle, we can use distance formula to find the radius.

r = √((1 - (-3))² + (8 - 4)²)

r = √(16 + 16)

r = √32

Now, formula for equation of a circle with centre (h, k) is;

(x - h)² + (y - k)² = r²

Our centre is (-3, 4) with r = √32

Thus;

(x - (-3))² + (y - 4)² = (√32)²

(x + 3)² + (y - 4)² = 32

Answer:

x=26

Step-by-step explanation:

first add the numbers

4x-8+34+76-x=180

4x+102-x=108

Then combine like terms

4x+102-x=180

3x+102=180

Subtract 102 from both sides of the equation

3x+102=108

3x+102-102=108-102

Simplify

3x=78

Divide both sides of the equation by the same term

3x=78

3x/3=78/3

simplify

cancel terms that are in both the numerator and denominator, divide the numbers

Solution

X=26

Step-by-step explanation:  5 20 21 02

There are 5 areas to calculate

Top  = LW          =  (20)(17)

Bottom  = LW    =  (20)(15)

Back  = LW        =  (20)(8)

2 Triangular Ends  = One square    = LW     =  (8)(15)

Total Surface Area = (20)(17) +  (20)(15) + (20)(8) +  (8)(15)

                  = (20)(17 + 15 + 8) +  (8)(15)

                  = (20)(40) + (8)(15)

                  =  800  +  120
