Answer:

AB is not a tangent to the circle

Step-by-step explanation:

The angle between a tangent and the radius at the point of contact = 90°

Using Pythagoras' identity to determine if the triangle is right at A

If the square of the longest side is equal to the sum of the squares on the other 2 sides then A is right.

longest side = 15 , then 15² = 225

8² + 9² = 64 + 81 = 145 ≠ 225

Then AB is not a tangent to the circle

A meal plan lets students buy $20 meal cards. Each meal card lasts about 8 days. write and graph equation
Luda [366]

Step-by-step explanation:

Given that,

A meal plan lets students buy $20 meal cards.

Each meal card lasts about 8 days.

Let us assume that y denotes number of days for a 20 dollar meal card i.e. $20 every 8 days.

Let x = number of $ for another day.

So,

y=\dfrac{8}{20}x+8

y=\dfrac{2}{5}x+8

Hence, this is the required equation.

A firecracker shoots up from a hill 160 feet high, with an initial speed of 90 feet per second. Using the formula H(t) = −16t2 +
Masja [62]

When the firecracker hits the ground, H(t) = 0.0 = -16t^2 + 90t + 160 Using the quadratic formula,t = (-90 +- sqrt(90^2 - 4(-16)(160))) / 2(-16)t = -1.42 ort = 7.04

The negative time is extraneous. Therefore,t = 7.04 s.

Seven Seconds is your answer!
