Exponential function has form y = a(b)^x

we see that when x = 0, then y = 10. Substitute those values to solve for an unknown

10 = a(b)^0

since b^0 is 1 we are left with a = 10.

we have y = 10(b)^x

to find b, use another point on the table. when x = 1, y = 30 so

30 = 10(b)^1
30 = 10b
b = 30/10
b = 3

function: y = 10 · (3)^x

(can also notice that y-values are all being mutliplied by 3)

Mr. F is buying 8 computers for the computer lab. if one computer costs $1,156, How much will the computers cost in all?

Andreas93 [3]

answer: $9248

explanation:

well, we know the cost for one, so if each computer costs the same, multiply the cost of one of them by 8 to get the total.

8 x 1,156 = 9248.

so, we can assume this is what the computers will cost in total because there seems to be no added tax or fees.

i hope this helps, and have a great day! don't hesitate to ask if you need more help with this specific question! ♥ - eviezoom

A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that

snow_tiger [21]

Answer:

$12800 + 100x \le 24000$

A maximum of 112 number of 100 - kilograms can be loaded in the container.

Step-by-step explanation:

Given that:

Weight of each crate = 100 kg

The greatest weight that can be loaded in the container = 24000 kg

Weight already loaded in the container = 12800 kg

To find:

The inequality to determine the value $x$ i.e. number of 100 - kilograms that can be loaded in the shipping container?

Solution:

Weight already loaded = 12800 kg

Let the number of 100 - kilograms that can be loaded in the container = $x$

Weight of $x$ = 100 $x$ kg

This combined weight nor be greater than the capacity of the container.

OR we can say, it must be lesser than or equal to greatest weight that can be loaded into the container.

$12800 + 100x \le 24000$

$100x \le 24000 - 12800\\\Rightarrow 100x \le 11200\\\Rightarrow x \le 112$

i.e. a maximum of 112 number of 100 - kilograms can be loaded in the container.

darcy likes to eat peanut butter and raisins on apple slices. on each apple slice she puts 1/16 cup of peanut butter and 8 raisi

netineya [11]

The answer is 7/10.

For one apple slice, Darcy needs 1/16 cup of peanut butter and 8 raisins. She has 2/5 cup of peanut butter. To compare how many butter she has and she needs we will divide 2/5 with 1/1

This means that Darcy needs 5/80 cup of peanut butter and 8 raisins.
If she has 32/80 cup of peanut butter, she will have it only fo 6 or 7 apple slices (32/80 ÷ 5/80 = 6.4) depending how it is rounded. If she prepares 6 apple slices, she will still have a little of peanut butter left (0.4 = 2/5 of cup). So, she will prepare 7 apple slices so the butter will be all gone.

For 7 apple slices, she needs 56 raisins (7 × 8 raisins).
That is 56 raisins out of 80 raisins, so fraction of the 80 raisins did she eat is:
 $\frac{56}{80} = \frac{7}{10}$

Expecting new arrivals, Ifa's Electronics laptops were marked down for 35 % off the initial price. A customer purchases a laptop

Fittoniya [83]

Answer: $835.88

Step-by-step explanation:

SP after 7% sales tax = 543.32

SP = MP (100 - d) / 100

543.32 = MP (100 - 35) / 100

543.32 = 0.65MP

MP = 835.88
