Answer:

Angle D equals 80 degrees.

Since both triangles and angles are congruent, you can use triangle ABC to find the measure of CDE.

ABC has to equal 180 degrees so that means that 30 + 70 + <B = 180

add: 100 + <B = 180

Subtract <B = 80

Angle B equals 80 degrees which also means that Angle D equals 80 degrees.

We know that angle B is 80 degrees since all angles in a triangle add up to 180 degrees.

70 + 30 + B=180, B=80

And we know that B=D since the two triangles are similar

Therefore angle D=80 degrees

If f(x) = 2x – 1 and g(x) = x2 – 3x - 2, find (f + g)(x).

LenKa [72]

Answer: Option B

$(f + g)(x)=x^2 - x - 3$

Step-by-step explanation:

In this problem we have the function

$f(x) = 2x - 1$

and the function

$g(x) = x^2 - 3x - 2$

They ask us to perform the operation:

$(f + g)(x)$

Therefore we must perform the algebaic summa of the function f plus the function g

$(f + g)(x)=f(x) + g(x)$

$(f + g)(x)=2x - 1 + x^2 - 3x - 2$

Now we siplify the expression

$(f + g)(x)=x^2 - x - 3$

Simora [160]

The equatorial diameter of the earth is 7925 mi.

<u>Solution: </u>

Given, The equatorial diameter of Jupiter is about 89,000 mi.

This is about 11.23 times the equatorial diameter of earth.

We have to find what is the equatorial diameter of earth? Round the nearest integer

Now, according to given information,

Equatorial Diameter of Jupiter = 11.23 $\times$ equatorial diameter of earth

$\text { Then, equatorial diameter of earth }=\frac{\text { diameter of iupiter }}{11.23}$

$\begin{array}{l}{\text { equatorial diameter of earth }=\frac{89000 \mathrm{mi}}{11.23}} \\\\ {\text { equatorial diameter of earth }=7925.2003 \mathrm{mi}}\end{array}$

Hence, the equatorial diameter of the earth is 7925 mi.

a. Any vector in the span of S is a linear combination of the vectors in S. The simplest one we could come up with is the addition of the two vectors we know:

p(x)=(-8x^2+4x-5)+(-2x+5)=\boxed{-8x^2+2x}
