The square will have area
.. (9 cm)^2 = 81 cm^2.
The two triangles together will have area
.. (9 cm)*(12 cm) = 108 cm^2.
The sum of the areas of those three shapes is
.. 81 cm^2 +108 cm^2 = 189 cm^2
Answer:
54
Step-by-step explanation:
its a sequence. they are multiplying by 3 each time.
Answer:
B (second graph from left)
Step-by-step explanation:
The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.
Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.
The equation that can be used to determine the number of cells after x hours is; y = 0.5x + 30.
<h3>Linear model Equations</h3>
It follows from the task content that;
- The scientist starts with a sample of 30 bacteria cells, it follows that the intercept of the linear model is 30.
Additionally, since the number of bacteria cells increases by 50% every hour implies that the rate of change, slope of the equation is 0.5.
Hence, the required equation is; y = 0.5x + 30.

Answer:

Step-by-step explanation:
<u>Inscribed Angle Theorem</u>
The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.
First, use the Inscribed Angle Theorem to calculate the measure of arc WY.
