Answer:

If you start from the "standard" sine function, i.e.

You can change its graph in four ways:

Amplitude: you can multiply the whole function by a constant to stretch/squeeze it vertically. The transformation looks like

Phase: you can add a constant to the argument translate it horizontally. The transformation looks like

Period: you can multiply the argument by a constant to stretch/squeeze it horizontally. The transformation looks like

Shift: you can add a constant to the whole function to translate it vertically. The transformation looks like

In your case, we're changing the period of the function. If 1 " alt=" k>1 " align="absmiddle" class="latex-formula"> the function is squeezed, so you're squeezing the graph horizontally by a factor of 7/4

If a sample of radioactive material has only 12.5% of the original radioactive parent material, how many half-lives have passed? a. 3

b. 5

c. 6.25

d. 12.5

The correct answer is A) 3.

We can set up the equation 0.5ˣ = 0.125 to solve this, since we want to know the number of consecutive halves that are taken to get 12.5% (12.5% = 12.5/100 = 0.125).

To solve this, use logarithms:

Some of the money that people deposit into a bank eventually becomes an injection into the economy when the bank .

some of the money that people deposit into a bank eventually becomes an injection into the economy when the bank : Loans the money When the bank loans the money, the bank basically circulate the money from the hands of the wealthy who did their saving into the hands of the one that need it to sustain their lifes or business, which will technically improve the economy as a whole

Some of the **money** that are being **deposited** by people into a **bank** eventually becomes an injection into the economy when the **bank** makes **loans**.

A **loan** simply refers to an amount of **money** that is being **borrowed** by a **borrower** from a **bank** or other **financial** institutions (**lender**), which is generally expected to be **paid** back to the **lender** at a specific period of time with an agreed **interest**.

In this context, we can infer and logically deduce that some of the **money** that are being **deposited** by account holders(people) into **banks**, eventually becomes an injection into the **economy** when the **bank** makes **loans **to eligible **borrowers**.

300ml costs 27p find the cost of a litre. URGENT

1l = 1000ml so the previous answer is almost correct but you need to multiply that by ten to get 90p

9 is the answer because 100ml is equal to 1 liter and to get 100ml we divide 300ml by 3 and to get the cost of a liter we divide 27 by 3 and get 9.

A donkey eats 3/9 of a hay bale a week. How many hay bales does he eat in 21 days?

In this question, we're trying to find how many bales of hay the donkey eats in 21 days.

We know that the donkey eats 3/9 of a hay bale a week.

Lets turn this into a whole fraction to make it easier to find the answer:

The donkey would eat 9/9, or 1 hay bale, in 3 weeks.

We know that 3 weeks is equivalent to 21 days (1 week = 7 days), so our answer would be one hay bale.

Answer:

One hay bale.

Answer:

1

Step-by-step explanation:

since a week is 1/3 of 21 days. ALl we need to do is 3/9 x 3 which =1
