Answer: First option is correct.

Step-by-step explanation:

Since we have given that

ABC is a triangle.

And we need to find the altitude of a triangle.

Altitude of a triangle is a line segment from a vertex and it is perpendicular to the base.

So, It must be perpendicular.

So, According to graph, AF is the required altitude of ΔABC.

Hence, First option is correct.

Using the Factor Theorem, which of the polynomial functions has the zeros 4, <img src="https://tex.z-dn.net/?f=%5Csqrt7" id="Tex
Serjik [45]

Answer:

B

Step-by-step explanation:

According to the Factor Theorem, if (<em>x</em> - <em>a</em>) is a factor (where <em>a</em> is a zero) of the polynomial P(x), then P(a) must equal zero.

Our zeros are 4, √7, and - √7. Hence, when evaluating P(4), P(√7), and P(-√7), all must evaluate to zero.

Testing each choice, we can see that only choice B is true. That is:

\displaystyle \displaystyle \begin{aligned} f(4)&= (4)^3 - 4(4)^2 - 7(4) + 28 \\ &= (64) - (64) - (28) + 28 \\ &= 0 \stackrel{\checkmark}{=}0 \\f(\sqrt{7}) &= (\sqrt{7})^3 - 4(\sqrt{7})^2 - 7(\sqrt{7}) + 28 \\ &= (7\sqrt{7}) - (28) - (7\sqrt{7}) + 28 \\ &= 0 \stackrel{\checkmark}{=} 0\\ f(-\sqrt{7}) &= (-\sqrt{7})^3 - 4(-\sqrt{7})^2 - 7(-\sqrt{7}) + 28 \\ &= (-7\sqrt{7}) - (28) + (7\sqrt{7}) + 28 \\ &= 0 \stackrel{\checkmark}{=} 0  \end{aligned}

In conclusion, our answer is B.

Choose the correct answer for the amount of interest earned in the following simple interest problem. A deposit of $4,000 at 9.5
ozzi

we know that

The simple interest formula is equal to

I=P*r*t

where

I is the simple interest

P is the principal ( the amount borrowed or deposited)

r is the interest rate

t is the time

in this problem we have

P=\$4,000\\ r=9.5\% = 0.095\\t=\frac{270}{365}

Substitute the values in the formula above

I=4,000*0.095*\frac{270}{365}

I=\$281.10

therefore

<u>the answer is</u>

The amount of interest earned is equal to \$281.10
