Lisa is asked to draw a triangle with the following specifications:

1 answer:

8 0

B is correct.

Since two of the angles are complementary, adding up to 90°, the third angle must be 180-90=90°.

However, this does not mean only one triangle exists. The only information we are given about the two angles is that they are complementary. This could be 30 and 60; 45 and 45; or multiple other combinations. This means there is more than one triangle that fits these criteria.

Answer:

x = - 2.5

Step-by-step explanation:

Given that the sketch represents

y = x² + bx + c

The graph crosses the y- axis at (0 , - 14), thus c = - 14

y = x² + bx - 14

Given the graph crosses the x- axis at (2, 0), then

0 = 2² + 2b - 14

0 = 4 + 2b - 14 = 2b - 10 ( add 10 to both sides )

10 = 2b ( divide both sides by 2 )

b = 5

y = x² + 5x - 14 ← represents the graph

let y = 0 , then

x² + 5x - 14 = 0 ← in standard form

(x + 7)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 2 = 0 ⇒ x = 2

The x- intercepts are x = - 7 and x = 2

The vertex lies on the axis of symmetry which is midway between the x- intercepts, thus

the x- coordinate of the turning point is $\frac{-7+2}{2}$ = $\frac{-5}{2}$ = - 2.5

F (x) = |x + 3| -1 . Find the average rate of change from x = -6 to x = 8

Elenna [48]

Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((|8 + 3| -1) - (|-6 + 3| -1))/(8 + 6) = ((|11| -1) - (|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7

5:35-5:52 I need how much minutes from 5:35 from 5:52 please answer

Greeley [361]

Since these both are on the same hour we'll ignore the 5. We end up having :35 and :52. We'll subtract 35 from 52 which gives us 17. The answer to this is 17 minutes.
