Answer:

A 20.8 cm

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

We know the length is 8cm and the width is 24mm

The need to be the same units to add them together

Change 24 mm * 1cm/10 mm = 2.4 cm

Substitute 8 cm for l and 2.4 cm for w

P = 2(8+2.4)

P = 2 (10.4)

P = 20.8 cm

Kamau is now 2 years older than Jane if James age is y now what will be the total age in 10 years

cluponka [151]

Answer:

(2y + 22) years

Step-by-step explanation:

kamau is now 2 years older than Jane if Janes age is y now what will be the total age in 10 years.

Answer: If Jane is y years old now and Kamau is 2 years older than Jane, therefore the age of Kamau now would be 2 + y years.

In ten years time Jane age would be y + 10 years while the age of Kamau would be y + 2 + 10 = y + 12 years.

To get their total age we just have to add their individual age. Therefore the total age in 10 years = Age of Kamau in ten years + age of Jane in ten years = (y + 12) + (y + 10) = y + 12 + y + 10 = y + y + 12 + 10 = 2y + 22 years

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given function

$g(x)=(\frac{2}{3})^x-2$

STEP 2: Plot the given function

STEP 3: choose the correct graph

It can be seen from the plotted graph in step 2 that:

$\begin{gathered} x-intercept:(-1.71,0) \\ y-intercept:(0,-1) \end{gathered}$

Hence, comparing the x-intercepts, the correct graph is seen in:
