Answer:

Step-by-step explanation:

Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:

5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3

3^2 = 9:

5×9 - 3 (3 - 2) + 3

3 - 2 = 1:

5×9 - 3 + 3

5×9 = 45:

45 - 3 + 3

45 + 3 = 48:

48 - 3

| 4 | 8

- | | 3

| 4 | 5:

Answer: 45

Find the average rate of change for fx) = x2 – 3x – 10 from x = 4 to x = 6.

Leviafan [203]

Answer:

Step-by-step explanation:

The rate of change is defined as

f(x2) - f(x1)

--------------------

x2-x1

x2 = 6

f(6) = x^2 – 3x – 10 = 6^2 -3*6 -10 = 36 - 18-10=8

x1 = 4

f(4) = x^2 – 3x – 10 = 4^2 -3*4 -10 = 16 - 12-10=-6

Substitute the values into the expression

8 - -6

--------------------

6-4

8+6

------------

Horace read 160 pages in 4 hours. How many pages can he read in 6 hours??

Rashid [163]

160/4 = p/6

Cross-multiply the propportion:

160 x 6 = 4p

Divide each side by 4:

p = 40 x 6 = 240 pages

CAN SOMEONE HELP ME FIND THE DISTANCE..

kirill115 [55]

The angle of elevation from point C to point A is $32^{\circ}$

<em><u>Solution:</u></em>

Given that we have to find the angle of elevation from point C to Point A

Given in figure that, angle A = $58^{\circ}$

Given is a right angled triangle ABC where angle B = $90^{\circ}$

We have to find angle C

The angle sum property of a triangle states that the angles of a triangle always add up to 180°

Therefore, in given triangle ABC

angle A + angle B + angle C = 180

$58^{\circ} + 90^{\circ} + C = 180^{\circ}$

$148^{\circ} + C = 180^{\circ}\\\\C = 180^{\circ} - 148^{\circ}\\\\C = 32^{\circ}$

Therefore angle C = $32^{\circ}$
