I NEED HELP ASAP! : An initial population of 175 quail increases at an annual rate of 22%. Write an exponential function to mode
goblinko [34]

Answer:

About 473 quails.

P=175(1.22)^t

Step-by-step explanation:

Exponential equation with P_0 as the initial amount and rate of r is:

P=P_0(1+r)^t

P=175(1+.22)^t

P=175(1.22)^t

After 5 years the population will be:

P=175(1.22)^5

P \approx 472.9739

So the population will be about 473 quails.

Find equation to the given value of the curve x=t^5+1, y=t^6+t, and t=-1. please help I keep getting y=-1.4x and it is incorrect
irakobra [83]
Well for the function of x we have x=t^5+1 and we know t= -1

So you plug in -1 instead of the t and you will get x=(-1)^5+1
Now just resolve that equation to get the value of x

x = (-1)^5+1 = -1+1 = 0 So x=0

Do the same with y and you’ll get y=2

I need help understanding this please

Answer:

<em>Alma needs $35.28 to purchase the lace for her pillow.</em>

Step-by-step explanation:

If it is a square, the length and the width would be the same. You have to take the square root of the area, so the square root of 324 is 18. Now, we know that the length is 18 cm and the width is also 18 cm. If she's selling every 2 centimeters for 98 cents, you have to find the total amount of centimeters the pillow has, so 18*4 (the 4 comes from the number of sides on the pillow)=72.

Now divide that answer by the 2 lace centimeters she will get. (72/2=36 cm).

Now multiply that by 98 cents, the cost. (36*0.98=35.28).

So Alma needs $35.28 to purchase the lace for her pillow.
