Assuming the percent is out of 100, we subtract 100-78 because milton is experiencing a decrease. If Milton were to experience an increase, we would have to add one to the .78 which would make it 1.78, but since that is not the case we know it is a decaying function.

Find k so that x + 2 is a factor of x ^ 3 - k * x ^ 2 + 2x + 7k. (If anyone could help me out with this that would be amazing!!)

Answers

Answer:

k = 4

Step-by-step explanation:

If x + 2 is a factor of the polynomial;

By the factor theorem, if we set x + 2 = 0, then make x the subject of the formula; if we substitute the value into the polynomial, the result we should have after calculating should be zero

So, we have it that;

x + 2 = 0

x = -2

Substitute into the polynomial and equate to zero

(-2)^3 - k (-2)^2 + 2(-2) + 7k = 0

-8 -4k -4 + 7k = 0

-12 -4k + 7k = 0

-12 + 3k = 0

-3k = -12

k = -12/-3

k = 4

A street light is 7.5 feet tall casts a 3-foot-long shadow A nearby flagpole casts a 16.5 foot long shadow what is the height of the flag pole

Answers

Answer:

h = 41.25 foot

Step-by-step explanation:

Given that,

Height of a street light = 7.5 feet

It casts a 3-foot-long shadow.

A nearby flagpole casts a 16.5 foot long shadow. We need to find the height of the flag pole. Let the height be h. It can be calculated as :

[tex]\dfrac{\text{height of street light}}{\text{height of shadow of street light}}=\dfrac{\text{height of flagpole}}{\text{height of shadow of the flag pole}}\\\\\dfrac{7.5}{3}=\dfrac{h}{16.5}\\\\h=\dfrac{7.5\times 16.5}{3}\\\\h=41.25\ foot[/tex]

So, the height of the flag pole is equal to 41.25 foot.

The height of the flag pole is 41.25 feet tall.

Word problems in mathematics are methods used to solve real-life cases. They usually follow a logical approach with the use of arithmetic operations when solving them.

From the parameters given:

If 7.5 feet tall  casts = 3-foot long shadow

Let the height of the flag pole be = x

∴

(x) feet tall casts = 16.5 foot long shadow.

To determine the height of the flag pole, we have:

[tex]\mathbf{x = \dfrac{7.5 feet \ tall \times 16.5 \ foot \ long} {3 \ foot \ long} }[/tex]

x = 41.25 feet tall

Jenny used a total of 3 5/6 gallons of gas while driving her car. Each hour she was driving, she used 7/9 gallons of gas. What was the total number of hours she was driving?

Answers

Answer:

Jenny drove for about 4.93 hours

Step-by-step explanation:

Jenny uses 7/9 gallons of gas per hour.

She used a total of 3 5/6 gallons.

If x is the number of hours she drove, then she used 7x/9 gallons.

X* 7/9 = 3 5/6

3 5/6 can be converted to an improper fraction.

((3*6)+5) / 6 = 23/6 gallons

=> x * 7/9 = 23/6

=> x = (23/6) / (7/9)

=> x = (23/6) * (9/7)

=> x = 69/14

=> x = 4.928571429 hours.

Find out whether the angles are adjacent or vertical. Then find the value of x.

Answers

Answer:

x = 20

Step-by-step explanation:

angles are adjacent and add up to 180 degrees, so:

8x + 20 = 180

8x = 160

x = 20

Answers

Answer:

The point (-6, 9) is also on the line. False

The line has a slope of . (this statment is incomplete!)

The line has a slope of . (this statment is incomplete!)

The line represents a direct variation function. True ( y=2/3x )

Answer:

Slope of the line through the points  (3,2), (6,4) is (4-2)/(6-3) = 2/3

"The line has a slope of 3/2".   False, the slope is 2/3 not 3/2

"The line represents a direct variation function".  True, as y = (2/3)x     (which is a direct variation)

"The line has a slope of 2/3". True (as just proved by number one)

"The point (-6,9) is also on the line".  Does y = (2/3) x 9 = (2/3) (-6) = -4?

The ground pool for a hot air balloon can see the balloon in the sky at an angle of elevation of 11°. The pilot radios the crew that the balloon is 950 feet above the ground. What is the horizontal distance from the balloon to the ground crew.

Answers

Answer:

4,886.83feet

Step-by-step explanation:

The question will result in a right triangle with

Opposite = distance of the balloon above the ground = 950feet

Angle of elevation = 11 degrees

Required

Horizontal distance h (adjacent)

Using SOH CAH TOA identity

Tan theta =opp/adj

Tan 11 = 950/h

h = 950/tan 11

h = 950/0.1944

h = 4,886.83feet

Hence the horizontal distance from the balloon to the ground crew is 4,886.83feet
