Answer:
Step-by-step explanation:
Exponential functions are represented in the form 
, where a is the initial value and b is the multiplier.
Here, we see that when x = 0, y = 4. This means that 4 is our initial value, or a. You can look at the a variable almost being like the y-intercept of a graph.
Next, we must solve for b. We can do 16 ÷ 4 to find the slope, or multiplier of this function, because 16 is 1 input x-value up from 0. 16 ÷ 4 = 4.
So, we now have all the needed variables, so we plug them into the formula
Answer:
Portion of walking in degrees = 72°
Step-by-step explanation:
The question is incomplete as the diagram is not shown in the question. I have attached the full question below. Consult it to understand the solution better
First calculate the percentage of walking from a total of all activities.
Percentage of walking = 10/50 · 100%
Percentage of walking = 20%
It means the portion of the circle(pie chart) for walking should be equal to 20% of the whole circle.
We know that the whole circle is equals to 360°
Circle = 360°
We need to calculate 20% of 360°, which will represent the portion of walking in degrees.
Portion of walking in degrees = 20/100 · 360°
Portion of walking in degrees = 72°
3(4)+6
12+6
The answer is 18
In general, 23 more than a number is written as
In our case, x is 'twice a number'; thus,
Finally, the whole expression is
<h2>The answer is 2n+23</h2>
Answer:
0.7% off
Step-by-step explanation:
9.67 × y = 9.6 × 100
9.67y = 960
9.67y ÷ 9.67 = 960 ÷ 9.67
y = 99.2
100% - 99.2% = 0.8%
