Answer:

f(1) = 1

Step-by-step explanation:

To evaluate a function, you see the y value it gives when you plug in the x value.

When you plug in 1 for the x value, the y value is also 1, so f(1) = 1

Trey wants to plant grass in his backyard. His backyard is in the shape of a rectangle. Its length is 31

salantis [7]

Find the total area of the yard in feet.

Area of a rectangle is length x width.

31 x 24 = 744

Divide the total area of the yard by the coverage of the seeds.

744/12 = 62

He will need 62 packs of seed.

Which equation is a quadratic model for the data set? Hint: Use a graphing calculator or a spreadsheet program.

Ivahew [28]

The equation that model a quadratic function is: y=0.9673x²-0.8475x+10.4334

Step-by-step explanation:

A quadratic function has the form of ;

f(x) = ax²+bx+c where a, b and c are real numbers and a≠0

For this case, equation y=0.9673x²-0.8475x+10.4334 models a quadratic function where a>0 thus the parabola opens upwards

If a bloodstain has a length of 3.0cm and a width of 1.5cm what is the angle of impact?

zalisa [80]

The angle of impact is 30°

<h3>What is the angle of impact?</h3>

In a bloodstain, the angle of impact can be used to determine the appearance of the resulting bloodstain if the bloodstain has a tail or pattern.

Bloodstain pattern analysis is the study of bloodstains at a scene of the crime in an attempt to reconstruct the events that resulted in the bloodshed.

Mathematically;

$\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{width \ stain}{length \ stain} )}$
