You joined an online coupon club. You earned 100 bonus points just by signing up. Each month you use the site, you earn another
Blababa [14]
So,

I'm assuming you want me to make a formula for figuring your points after any given month assuming that you use the site at least once a month and you don't spend your points.

After one month, you will have your base 100 points plus an additional 10 points.

100 + 10 = 110

After two months, you will have gained an additional 10.
110 + 10 = 120

We can put this into a function, where P is your points, and m is the number of months you use the site.

P(x) = 100 + 10m

So after 500 months, you will have:

P(x) = 100 + 10(500) = 5100 points!

This is identical with:
y = 100 + 10m

and

y = 10m + 100

So this can be graphed as a linear equation/function with a y-intercept of 100 and a slope of 10/1.

Which equation requires the division property of equality to be solved?
Ymorist [56]

Answer:

A. 201.6 = 11.2f

Step-by-step explanation:

we solve for each unknown to verify which equality will require the division property:

#A. 201.6 = 11.2f

201.6=11.2f\\\\f=\frac{201.6}{11.2}=201.6\div 11.2\\\\=18

Hence, division property used.

#B. 35.4=Z ÷ 3.1

35.4=Z\div 3.1\\\\35.4=\frac{Z}{3.1}\\\\Z=35.4\times 3.1\\\\=109.74

Hence, multiplication property used.

#C. t/3.2=15.1

\frac{t}{3.2}=15.1\\\\t=15.1\times 3.2\\\\=48.32

Hence, multiplication property used.

#D. 201.6 = 11.2+c

201.6=11.2+c\\\\201.6-11.2=c\\\\c=190.4

Hence, subtractionproperty used.

Which expression is equivalent to (4(5^3)1/2?
Feliz [49]

Answer:

10\sqrt{5}

Step-by-step explanation:

In this problem, we are given expression in exponent form and we have to simplify the expression.

The expression is [4(5^{3} )]^{\frac{1}{2} }

Now, we know that 5^{3} = 5 \times 5 \times 5 = 125

So, 4(5^{3} ) = 4 \times 125 = 500

Now, 500 can be written as 100 × 5 = 10² × 5

Therefore, [4(5^{3} )]^{\frac{1}{2} } = (500)^{\frac{1}{2} } = 10\sqrt{5} {Since 500 = 100 × 5 = 10² × 5} (Answer)
