vampirchik [111]

Answer:

<u>If Caeli  will use all of the fabric she has, the base of the flag should be of 4 feet.</u>

Step-by-step explanation:

1. Let's review the information provided to answer the question correctly:

Area of the fabric Caeli  has and want to use and design = 10 square feet

Height of the rectangle of the rectangle shape = 2.5 feet

2.  What is the base of the flag if she will use all of the fabric she has?

Area of the shape of the rectangle = Height of the flag * Base of the flag

Replacing with the real values:

10 square feet = 2.5 feet * Base of the flag

10 square feet/2.5 feet = Base of the flag

<u>Base of the flag = 4 feet</u>

<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>

F(x)=2x^(2)-5x-20 find f(-9)
Fed [463]

Answer:

<h2>187 </h2>

Step-by-step explanation:

f(x) = 2 {x}^{2}  - 5x - 20

To find f(-9) , substitute the value of x that's - 9 into f (x). That is for every x in f(x) replace it with - 9

We have

f( - 9) = 2 ({ - 9})^{2}  - 5( - 9) - 20 \\  = 2(81) + 45 - 20 \\  = 162 + 25 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \\  = 187 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help
faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) = \frac{adjacent}{hypotenuse }

      cos(40) = \frac{x}{4}

      0.766 ≈ \frac{x}{4}

      3.06 ≈ x

      x ≈ 3.06
