The exponential function represented in the table is given by:
[tex]F(x) = 16\left(\frac{3}{2}\right)^x[/tex], which means that option F is correct.
What is an exponential function?It is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value.b is the rate of change.Considering the table, that has points (2,36) and (3,54), we have that:
[tex]36 = ab^2[/tex]
[tex]a = \frac{36}{b^2}[/tex]
[tex]54 = ab^3[/tex]
[tex]54 = \frac{36}{b^2} \times b^3[/tex]
[tex]36b = 54[/tex]
[tex]b = \frac{3}{2}[/tex]
Hence:
[tex]y = a\left(\frac{3}{2}\right)^x[/tex]
When x = 2, y = 36, hence:
[tex]y = a\left(\frac{3}{2}\right)^x[/tex]
[tex]36 = a\left(\frac{3}{2}\right)^2[/tex]
[tex]\frac{9}{4}a = 36[/tex]
[tex]a = 16[/tex]
Hence, the function is:
[tex]F(x) = 16\left(\frac{3}{2}\right)^x[/tex], which means that option F is correct.

The sum of two consecutive numbers is 91. Find the numbers
Answer:
45 and 46
Step-by-step explanation:
let x = the smaller number
thus, x + 1 is the next consecutive number
x + x + 1 = 91
2x + 1 = 91
2x = 90
x = 45
x + 1 = 46
Answer:
1 + x = 1 + 45 = 46, so the 2 consecutive numbers are 45 and 46, when added, gives the sum of 91..

A candlestick burns at a rate of 0.2 inches per hour. After eight straight hours of burning, the candlesticks 13.4 inches tall. Write and solve a linear equation to find the original height of the candle.
Answer:
w43324424
Step-by-step explanation:
Answer:the original height of the candle is 14.8 inches
Step-by-step explanation:A Candlestick burns at a rate of 0.2 inches per hour. It means that the height of the candle is decreasing by 2 inches per hour. This decrease is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed asTn = a + (n - 1)dWhere a represents the first term of the sequence.d represents the common difference.n represents the number of terms in the sequence.From the information given,d = - 0.2 (it is decreasing)n = 8T8 = 13.4 inchesWe want to determine the value of the first term, a. Therefore,13.4 = a - 0.2(8 - 1)13.4 = a - 1.4a = 13.4 + 1.4 = 14.8 inches

Kiran’s backpack weighs 3 pounds less than Clare’s backpack. Clare’s backpack weighs 14 pounds. How much does Kiran’s backpack weigh? WHICH ANSWER IS CORRECT
x+3=14
3x=14
x=14−3
x=143
Answer:
[tex]x = 14 - 3[/tex]
Step-by-step explanation:
*The key word 'less than' means to subtract.
x + 3 = 14 is incorrect. Kiran isn't adding weight to his backpack.
In other words, the backpack didn't increase in pounds.
3(x) = 14 is incorrect. Multiplying is irrelevant to this problem, it's not saying Kiran's backpack is 3 times a number equal to Clare's backpack weight.
x = 143 is incorrect. This equation is unrealistic.
x = 14 - 3 is correct. This equation is explaining that Kiran's backpack is 3 pounds less than Clare's backpack (14)
The function for the speed of a ball thrown straight up in the air is given by v(t) = 128 − 32t, where v is the ball's velocity (in feet per second) and t is the number of seconds after the ball is thrown.
What is the slope? What does it represent? (1 point)
−32; velocity decreases at rate of 32 feet per second as the time increases
32; velocity increases at rate of 32 feet per second as the time increases
−128; velocity decreases at rate of 128 feet per second as the time increases
128; velocity increases at rate of 128 feet per second as the time increases
Answer:
A) −32; velocity decreases at rate of 32 feet per second as the time increases
Step-by-step explanation:
Rewrite v(t) = 128 - 32t as v(t) = -32t + 128
We see that our slope is -32 ft/s given it's in slope-intercept form with an initial height of 128 feet.

A company starts to track the number of phone calls received each month. During the first month the company received 4,264 phone calls. During the second month the company received 25% more phone calls than in the first month. During the third month the company received 6,396.
What was the percent increase in the number of phone calls from the second month to the third month.
Pleaseeee answer fastt
Answer:
Percent increase : 20%
Step-by-step explanation:
First month: 4,264 phone calls.
Second month: 25% more phone calls than in the first month.
To know the total phone calls received during this month you must take 25% of 4,264 and then add it to the 4,264 call of the first month:
64,264*25%=1,066
Total phone calls of the second month: 1,066+ 4,264= 5,330
You can also calculate the total phone calls of the second month by multiplying 4264 times 1,25 because times 1 is the same number and times 0,25 is the percent increase in the number of calls:
4,264*1,25= 5,330
Third month: 6,396 phone calls
To know the percent increase in the number of phone calls from the second month to the third month you must use the percent change formula:
Percent change: ((value2-value1)/ value 1 )*100%
Value 2: phone calls received during the third month
Value 1: phone calls received during the second month
Percent change: ((6,396-5,330)/ 5,330 )*100%
Percent increase: 20%

How can cell Survival be predicted
Answer:
Introduction. Cellular survival depends on an organism's ability to respond and adapt to extracellular signals in its environment. Signal transduction is, therefore, an important biologic process, allowing cells to react to a variety of these extracellular stimuli and respond adaptively.

Why do you think there were more than 20 riots across the nation that summer
Answer:
beacuse it was so hot and people were stealing alot and thir king suks
Step-by-step explanation:
Answer:
In the summer of 1919, over 20 race riots broke out across the nation. The worst violence occurred in Chicago. African Americans went to White Beach only and that started violence. Each sides started throwing stones at each other, and a person drowned. A full-scale riot then erupted in the city. Angry African Americans attacked white neighborhoods while whites attacked African American neighborhoods. In the end, 38 people died—15 white and 23 black—and over 500 were injured. The most serious racial outbreak occurred in Chicago late in July of the Red Summer. A African American drifted into water that was customarily used by whites, White swimmers commanded him to return to his part of the beach, and some threw stones at him. The man drowned and that caused a riot between African American and White people. 38 people had been killed, including 15 whites and 23 blacks. Hope this helps!
