QuestionFind the height of a hot-air balloon at $t = 7$ minutes using the equation $y = 870 - 14.8t$ .

Studdy Solution

STEP 1

Assumptions1. The height of the hot-air balloon at time $t$ is given by the equation $y=870-14.8 t$ . We need to find the height at $t =7$ minutes

STEP 2

We need to substitute $t =7$ into the equation to find the height $y$ .
$y =870 -14.8 \times t$

STEP 3

Substitute $t =7$ into the equation.
$y =870 -14.8 \times7$

STEP 4

Perform the multiplication operation.
$y =870 -103.6$

STEP 5

Subtract $103.$ from $870$ to find the height $y$ .
$y =870 -103. =766.4$ The height of the hot-air balloon at time $t =7$ minutes is $766.4$ feet.

STEP 1

Assumptions1. The height of the hot-air balloon at time ttt is given by the equation y=870−14.8ty=870-14.8 ty=870−14.8t . We need to find the height at t=7t =7t=7 minutes

STEP 2

We need to substitute t=7t =7t=7 into the equation to find the height yyy.y=870−14.8×ty =870 -14.8 \times ty=870−14.8×t

STEP 3

Substitute t=7t =7t=7 into the equation.y=870−14.8×7y =870 -14.8 \times7y=870−14.8×7

STEP 4

Perform the multiplication operation.y=870−103.6y =870 -103.6y=870−103.6

STEP 5

Subtract 103.103.103. from 870870870 to find the height yyy.y=870−103.=766.4y =870 -103. =766.4y=870−103.=766.4The height of the hot-air balloon at time t=7t =7t=7 minutes is 766.4766.4766.4 feet.
