ANSWER

$< \: - 3, -2 \: >$

EXPLANATION

The given vectors are:

$u = < \: - 3,5 \: >$

and

$v= < \: 6, - 3\: >$

$- u - v = - 1< \: - 3,5 \: > -1 < \: 6, - 3\: >$

Use the scalar to multiply and obtain;

$- u - v = < \: 3, - 5 \: > + < \: - 6, 3\: >$

Simplify to get:

$- u - v = < \: 3 - 6, - 5 + 3 \: >$

$- u - v = < \: - 3, -2 \: >$

Find the value of c that makes x^2+26x+c a perfect-square trinomial.

MakcuM [25]

C = 169

square is (x + 13)^2

Explanation:

In the form:
ax^2+ bx +c
to complete the square a = 1 is required.
c = (b/2)^2
the square term is b/2
x^2 + 26x + c
a = 1 so we are okay to complete the square.
b = 26
c = (26/2)^2 = 13^2 = 169
finally to complete the square:
x^2 + 26x + 169 = (x+b/2)^2 = (x+13)^2

Answer:

$\frac{200}{3}$ square units

Step-by-step explanation:

Knowing the function and that the triangle is formed by both the x and y-axis, you already have the triangle's height, which is 10 (the y-intercept of the functon) To find the base length, all you have to do is find the x-intercept. To do that, simply:

Set function equal to 0 and solve for x:

f(x) = 10 - $\frac{3}{4}$ x

0 = 10 - $\frac{3}{4}$ x

$\frac{3}{4}$ x = 10

x = $\frac{40}{3}$

This means that the base length of the triangle is also $\frac{40}{3}$ . Now that you have the height and base length, you can

Plug values into the formula for the area of a triangle:

The area of a triangle is $\frac{1}{2}$ × height × base

Height = 10, base = $\frac{40}{3}$

Area = $\frac{1}{2}$ × 10 × $\frac{40}{3}$

Area = 5 × $\frac{40}{3}$

Area = $\frac{200}{3}$
