d now is moving straight west. When the cruiser is 0.9 mile south of the intersection and the car is 1.2 miles to the west, the police officers determine with radar that the distance between them and the car is increasing at 25 mph. If the cruiser is moving at 60 mph at the instant of measurement, what is the speed of the car?

san4es73 [151]

Answer:

<em>A) -3 + 9 + 4</em>

Step-by-step explanation:

We are given the following information: At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was  9°F greater than the temperature at 7:00 a.m. This means the temperature at 6:00 p.m. is calculated as -3 + 9.

We know this last temperature is 4°F less than the temperature at noon, thus the temperature at noon is calculated as -3 + 9 + 4

A) -3 + 9 + 4

A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions o
yKpoI14uk [10]

Answer:

  100%

Step-by-step explanation:

When the dimensions double, the perimeter doubles.

The percent change can be found from ...

  percent change = ((new value)/(old value) -1) × 100%

Filling in your values, you have ...

  percent change = ((2×(old perimeter))/(old perimeter) -1) × 100%

  = (2 - 1) × 100%

  = 100%

The perimeter increases by 100% from the first garden to the second.

Write an equation in slope-intercept form that describes the line with a slope of -2 and (5,4) is on the line
marin [14]

Answer:

The equation in slope-intercept form will be:

  • y = -2x + 14

Step-by-step explanation:

Given

  • slope = m = -2
  • point (5, 4)

We know that the slope-intercept form of the line equation is

y = mx+b

where m is the slope of the line and b is the y-intercept

substituting m = -2 and the point (5, 4) in the slope-intercept form to get the y-intercept 'b'

y = mx+b

4 = -2(5) + b

4 = -10 + b

b = 4+10

b = 14

now substituting m = -2 and b = 14  in the slope-intercept form to get the equation in slope-intercept

y = mx+b

y = -2x + 14

Therefore, the equation in slope-intercept form will be:

  • y = -2x + 14
