Answer:

640 m

Step-by-step explanation:

We can consider 4 seconds to be 1 time unit. Then 8 more seconds is 2 more time units, for a total of 3 time units.

The distance is proportional to the square of the number of time units. After 1 time unit, the distance is 1² × 80 m. Then after 3 time units, the distance will be 3² × 80 m = 720 m.

In the additional 2 time units (8 seconds), the ball dropped an additional

... (720 -80) m = 640 m

_____

<em>Alternate solution</em>

You can write the equation for the proportionality and find the constant that goes into it. If we use seconds (not 4-second intervals) as the time unit, then we can say ...

... d = kt²

Filling in the information related to the first 4 seconds, we have ...

... 80 = k(4)²

... 80/16 = k = 5

Then the distance equation becomes ...

... d = 5t²

After 12 seconds (the first 4 plus the next 8), the distance will be ...

... d = 5×12² = 5×144 = 720 . . . meters

That is, the ball dropped an additional 720 -80 = 640 meters in the 12 -4 = 8 seconds after the first data point.

The total cost in dollars for Larry to have his birthday party at a local
luda_lava [24]

Answer:

0 \leq p < 6

Step-by-step explanation:

Given

t = 6.95p + 29.95

Amount = 70

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in t = 6.95p + 29.95

70 = 6.95p + 29.95

Collect Like Terms

6.95p = 70 - 29.95

6.95p = 40.05

Solve for p

p = 40.05/6.95

p = 5.76

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: 0 \leq p < 6

Please help ‼️‼️ I’m doing functions
eduard
In this problem, you're looking for the value of t, so that f(t) = 48. That means if you put t into 5t-7, you'll get 48. To do this set up and solve an equation for t by setting 48 equal to 5t-7:
5t-7=48

Isolate the variable by adding 7 to both sides. 
5t=55

Divide by 5 on both sides to find t.
t=11

The answer is 11.

PLEASE helppp. What equation describes a line that is perpendicular y=-2/7x+5 and has the same y-intercept as y = 3x - 2?
svp [43]

Answer:

y = 7/2 -2

Step-by-step explanation:

if the slope of the first problem is -2/7 then its perpendicular is 7/2 (the exact opposite) and since the y- intercept is the b in Y= mx +b the intercept of the equation you’re trying to find is -2
