Consider the following graph of y = f (x).
I need help

Answer:

55°

Step-by-step explanation:

In triangle BAC, angle C =

180° - 90° - 70°

Angle C = 20°

In triangle DAB, angle C =

180° - 90° - 55°

Angle C = 35°

Add both angles

20° + 35° = 55°

Answer:

31.9secs

6,183.3m

Step-by-step explanation:

Given the equation that models the height expressed as;

h(t ) = -4.9t²+313t+269

At the the max g=height, the velocity is zero

dh/dt = 0

dh/dt = -9,8t+313

0 = -9.8t + 313

9.8t = 313

t = 313/9.8

t = 31.94secs

Hence it takes the rocket 31.9secs to reach the max height

Get the max height

Recall that h(t ) = -4.9t²+313t+269

h(31.9) = -4.9(31.9)²+313(31.9)+269

h(31.9) = -4,070.44+9,984.7+269

h(31.9) = 6,183.3m

Hence the maximum height reached is 6,183.3m

Answer:

$2.00

Step-by-step explanation:

For cost $4.23  cost of 1 pound apple = $1.9

For cost $5.9   cost of 1 pound apple = $1.7

For cost $7.61   cost of 1 pound apple = $1.7

For the given mixed fraction,

[tex]2\frac{1}{2}[/tex] pound

The simple faction of  it = 5/2 pound

Now dividing 5 by 2 to get decimal form,

Therefore,

5/2 pound = 2.25 pound

2.25 pound apple cost = $4.23

Hence 1 pound cost = 4.23/2.25

                                  = $1.9

For the given mixed fraction,

[tex]3\frac{1}{2}[/tex]

The simple faction of  it = 7/2

Now dividing 5 by 2 to get decimal form,

Therefore,

7/2 = 3.5

Since, cost of 3.5 pound apple = $5.9

Therefore,

1 pound apple = 5.9/3.5

                        = $1.7

For the given mixed fraction,

[tex]4\frac{1}{2}[/tex]

The simple faction of  it = 9/2

Now dividing 5 by 2 to get decimal form,

Therefore,

9/2 = 4.5

Since, cost of 4.5 pound apple = $7.61

Therefore,

1 pound apple = 7.61/4.5

                        = $1.7

Answer:

Step-by-step explanation:

Answer:

A = $2130.49

Step-by-step explanation:

Given the following data;

Time, t = 5 years

Interest rate, r = 8%

Principal = $1450

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 1450(1 + \frac{8}{100})^{5}[/tex]

[tex] A = 1450(1 + 0.08)^{5}[/tex]

[tex] A = 1450(1.08)^{5}[/tex]

[tex] A = 1450 * 1.4693 [/tex]

A = $2130.49

Answer:

[tex]distance = \sqrt{ {( - 3 - 3)}^{2} + {( - 1 - ( - 9))}^{2} } \\ = \sqrt{36 + 64} \\ = \sqrt{100} \\ = 10 \: units[/tex]

Answer:

c) H0 : p = 5.8%

H1 : p > 5.8%

Step-by-step explanation:

At the null hypothesis, we test that the percentage is equal to a certain value. At the alternate hypothesis, we have a test about this percentage, if it is more, less, or different from the tested value.

A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness

At the null hypothesis, we test if the percentage is 5.8%

[tex]H_0: p = 5.8\%[/tex]

At the alternate hypothesis, we test if this percentage is more than 5.8%. So

[tex]H_a: p > 5.8\%[/tex]

This means that the correct answer is given by option c.

Answer:

c) H0 : p = 5.8%

H1 : p > 5.8%

Answer:

≈ 42.85

or 30π

semi-circle is (dπ)*1/2 +d , but we don't need the +d since we don't have that edge so you only use (dπ)*1/2.

From there, and equalateral triangle has all the same sides, so you can assume that the two sides of the triangle added up would be 24.

Finally you add the product of (dπ)*1/2 with 24, and depending on whether it needs to be in exact terms (the decimal) or in terms of pi (the 30 one) you can change it to how it needs to be.
