6 0

Answer:

13) cos D = 0.4706

14) cos G = 0.28

15) cos M = 0.6667

Step-by-step explanation:

13) Cos D = 8/17 = 0.4706

14) GI² = 7² + 24²

GI² = 49 + 576 = 625

GI = 25

cos G = 7/25 = 0.28

15) MN² = 3²- (√5)²

MN² = 9 - 5 = 4

MN = 2

cos M = 2/3 = 0.6667

Determine the value of a, b, and c for the quadratic equation: 4x2- 8x = 3
Rufina [12.5K]

Answer:

B. a = 4, b = -8, c = -3

Step-by-step explanation:

The quadratic equation given is:

4x^2- 8x = 3

The general form of a quadratic equation is given as:

ax^2 + bx +c = 0

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

4x^2- 8x = 3\\\\4x^2 - 8x - 3 = 0

Therefore, by comparing:

a = 4

b = -8

c = -3

The correct option is B

Suppose f is a function. If 10 = f(-4), find the coordinates of a point on the graph of f?
Rashid [163]

Given:

For a function f, 10 = f(-4).

To find:

The coordinates of a point on the graph of f.

Solution:

We have,

10 = f(-4)

It means the value of function f is 10 at -4.

On a coordinate plane x-axis represents the input values and y-axis represents the output values of a function. So,

x-coordinate = input value = -4

y-coordinate = output value = 10

Therefore, the required coordinates of a point on the graph of f are (-4,10).
