To solve this problem you must follow the proccedure shown below:

 1. You have the following information given in the problem above:

 - <span>Marta is making 3 servings of fruit salad.
 - Marta adds 3/8 cups blueberries for each serving.
 - Her measuring cup holds 1/8 cup.

 2. Then, you have:

 1 time----1/8 cup 
         x----3/8 cups

 x=(3/8)/(1/8)

 x= 3x8/1x8
 x=24/8
 x=3 times

 H</span><span>ow many times must Marta measure 1/8 cup of blueberry to have enough for the fruit salad?

 The answer is: 3 times</span>

Which function is an example of exponential growth? y = 2(0.3)x y = 1.5(0.4)x y = 3(8)x y = 2(0.7)x
4vir4ik [10]
Exponential equation is
y=a(b)ˣ

when b>1, it is growth
when 0>b>1, it is decay

so

we want the 2nd number to be more than 1
that would be the 3rd one, y=3(8)ˣ

HELP what's the distance for this question? ​
jeyben [28]

Answer:

Distance = 38.57ft

Step-by-step explanation:

Given

Base = 60

\theta = 50

Required

The distance between the top and John

The distance is calculated using:

sin\alpha =  \frac{Distance}{Base}

Where

\alpha = 90 - \theta --- the angle between the diagonal line and the vertical line

\alpha = 90 - 50

\alpha = 40

So, we have:

Sin(40) = \frac{Distance}{60}

Distance = 60 * sin(40)

Distance = 60 * 0.6428

Distance = 38.57ft

Distance = 986 * tan(38)

Distance = 986 * 0.7812

Distance = 770ft<em> --- approximated</em>

Please help me with this thanks

<span> When area is equal 1120. We can write an equation
(x+4)(-x+64)=1120
-x²-4x+64x+256=1120
-x²+60x+256-1120=0
-x²+60x-864=0
D=b² - 4ac= 3600-4*864=144, √D=12
x= (-b+/-√D)/2a
x=(-60+/-12)/(-2)
x=24, x=36
For x=24
(x+4)=24+4=28
(-x+64)=(-24+64)=40
For x=36
(x+4)=36+4=40
(x-64) =(-36+64)=28
So sides should be 28 and 40 in.
We did not get any extraneous solutions. They could be if we get negative length side, for example. They can come because a quadratic equation can
give positive and negative numbers because a^2  and (-a)^2 give the same positive number.
We chose to solve this equation using formula for quadratic equations, because this equation has too big numbers to solve it using other methods.

HELP PLEASE!

D.
first, eliminate B and C, because the highest degree in these two equation is 3, a 3-degree equation has 3 roots, not 4. 

between A and D, A has the roots 0, 0, 7, and -7, all real roots.

D can be factored into (x²-49)(x²+1)=0
x²=49 or x²=-1
x=7 or -7, x=i or -i    two real roots, two unreal roots 

for the second equation: 
first, find the first term by using the formula:
the nth term=the first term + (n-1)*difference
you are given the 13th term and d=3.7
a13=a1+(13-1)d
1.9=a1+12*3.7
a1=-42.5

the sum of the first 13 terms is S=(a1+a13)*(13/2)=(-42.5+1.9)*6.5=-263.9
