Answer:

B) Adjacent

Step-by-step explanation:

The hypotenuse will ALWAYS be designated as the longest side in a right triangle.

Pretend that the angle (the one with the round line) is an eyeball that is looking outwards. The eye is looking out at side BC. That means that line BC is opposite of the angle.

This leaves one side left: the adjacent side. The adjacent side is the side next to the angle. But it is the side that is NOT the hypotenuse.

We have the expressions:

$f(x)=x^2+6x+15$ $y=x^2-4x+9$ $f(x)=x^2-8x$ $y=x^2+7x-2$

Now, with this we operate as follows:

$f(x)=x^2+6x+15=x^2+6x+9+15-9$ $\Rightarrow(x+3)^2+6$

Then, the axis is x = -3 and the vertex (-3, 6)

$y=x^2-4x+9=x^2-4x+4+9-4$ $\Rightarrow(x-2)^2+5$

Then, the vertex is (2, 5) and the axis is x = 2.

$f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4$

Then, the vertex is (2, -4) andd the axis is x = 2.

$y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}$ $\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}$

Then, the vertex is (-7/2, -57/4) and the axis is -7/2.

Adam borrowed $5,600 from the bank. The bank charges 4.2% simple interest each year.

Igoryamba

Answer:

$235.2

Step-by-step explanation:

Given data

Principal= $5,600

Rate= 4.2%

Time= 1 year

The expression for the simple interest is given as

SI= PRT/100

substitute

SI= 5600*4.2*1/100

SI= 23520/100

SI=$235.2

Hence after 1 year he will pay $235.2

Corey spent 25% of his savings on a printer at Louie’s Electronics.

KengaRu [80]

Let c represent the original amount that this guy had saved up.

He spent 25% of this amount, or 0.25c, on the printer.

To progress further, we have to know how much the printer cost.

Supposing that the printer cost $100 (which we do not know as a fact), this would be equal to 0.25c.

Thus, his savings originally amounted to c = $100/0.25 = $400.

What is the estimated number of hawks building a nest in the population?

Andrew [12]

12/72 is equivalent to 1/6

1/6 of the population are building a nest

1/6 of 10,800 is 10,800/6 which is 1,800
about 1,800 are building a nest

Jordan were successful in 10 out of 15 foul shots. What percent of shots was she successfull?(round your answer to the nearest t

Vesna [10]

First divide the numerator ( 10 ) by the denominator ( 15 ) to get around .666666667, now that is in decimal form, time convert to percentage multiply by 100 to get around 66.66666667 percent. Now round up to the nearest tenth to get 66.7 percent.
We rounded up since 6 in the hundredths place is greater than it equal to 5.
