Answer:

Step-by-step explanation:

Given

x² + 2x + 1 = 17 ( subtract 1 from both sides )

x² + 2x = 16

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 16 + 1

(x + 1)² = 17 ← take the square root of both sides

x + 1 = ± $\sqrt{17}$ ← subtract 1 from both sides

x = - 1 ± $\sqrt{17}$

1.) Max is driving 42 miles per hour. A dog dog runs into the street and max reacts in about three quarters of a second. What is

Nostrana [21]

Answer: $14.07\ m$

Step-by-step explanation:

Given

Max is driving at a speed of $42\ mph$

It took him three-quarters of a second i.e. $0.75\ s$

Speed in meter per second is $18.77\ m/s$

Distance is given by

$d=v\times t$

Reaction distance is

$d=18.77\times 0.75=14.07\ m$

The measure of one angle is six more than half the measure of another angle. If the angles are complementary, find both measures

Snowcat [4.5K]

Answer:

The measures of the two angles are 34° and 56°

Step-by-step explanation:

* Lets explain how to solve the problem

- The complementary angles are the angles whose the sum

of their measures is 90°

- The measure of one angle is six more than half the measure

of another angle

- Let the measure of the second angle angle is x

∵ The measure of the 2nd angle is x

∵ The measure of the first angle is 6 more than the half of the

measure of the second angle

∴ The 1st angle is 6 + 1/2 x

∵ The two angles are complementary

∴ The sum of their measures is 90°

∴ x + (6 + 1/2 x) = 90

∴ (x + 1/2 x) + 6 = 90

∴ 3/2 x + 6 = 90

- Subtract 6 from both sides

∴ 3/2 x = 84

- Multiply both sides by

∴ 3x = 168

- Divide both sides by 3

∴ x = 56

∵ x is the measure of the 2nd angle

∴ The measure of the 2nd angle is 56°

∵ The measure of the 1st angle = 6 + 1/2 x

∵ x = 56

∴ The measure of the 1st angle = 6 + 1/2(56) = 34°

* The measures of the two angles are 34° and 56°
