Cathrine has £7000 to invest.

Anvisha [2.4K]

Since this is a compound interest problem, you have to take note that the amount Catherine will get per year is not the same. It will increase per year since it is compounded. So first, we get the amount after one year. This will be 7000 x 0.04 which is 280 plus 7280. In the second year, she will get 7571 (7280 x 0.04 + 7280). In the third year, she will get 7874 (7571 x 0.04 + 7571). In the fourth year, she will get 8189 (7874 x 0.04 + 7874). And finally in the fifth year, she will get 8517 (8189 x 0.04 +8189). So after five years, she has 8517

PLEASE HELP 100 POINTS! NEED HELP ASAP

jenyasd209 [6]

Answer:

see the explanation

the graph in the attached figure

Step-by-step explanation:

Let

x ----> the number of bags of popcorn

y ---> the number of drinks

we know that

The price of each bag of popcorn was $5

The price of each drink was half the price of a bag of popcorn

The price of each drink was $5/2=$2.5

Remember that

The number of bags of popcorn and drinks Judy bought, multiplied by their prices, should equal $30.

The linear equation that represent this situation is

$5x+2.5y=30$

To graph the linear equation , find the intercepts

Find the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

In the context of the situation, the y-intercept represent the number of drinks Judy can buy when the number of bags of popcorn equals zero

For x=0

$5(0)+2.5y=30$

$2.5y=30$

$y=12\ drinks$

The y-intercept is the point (0,12)

Find the x-intercept

The x-intercept is the value of x when the value of y is equal to zero

In the context of the situation, the x-intercept represent the number of bag of popcorn Judy can buy when the number of drinks equals zero

For y=0

$5x+2.5(0)=30$

$5x=30$

$x=6\ bags\ of\ popcorn$

The x-intercept is the point (6,0)

To graph the line plot the intercepts and join the points

using a graphing tool

79 to the power of 3 = pi times 25 times h divided by 3

dolphi86 [110]

Answer:

$h=\frac{79^3 * 3}{25\pi}$

Step-by-step explanation:

Here, we have to find the value for h, in terms of $\pi$ .

Assuming The equation is:

$79^3=\frac{\pi*25*h}{3}$

We cross multiply to get:

$79^3=\frac{\pi*25*h}{3}\\79^3 * 3 = 25\pi h\\$

Now, we divide both sides by $25\pi$ to get an expression of h in terms of $\pi$ :

$h=\frac{79^3 * 3}{25\pi}$

Find the complement of an angle whose measure is 38

marissa [1.9K]

Answer:

Step-by-step explanation:

Complementary angles are two angles that add up to equal 90 degrees

90-38= 52

Therefore the complementary angle or "complement" of 38 is 52 degrees
