General form of an exponential function: [tex]\sf y=ab^x[/tex]
where:
a is the y-intercept (or initial value)b is the base (or growth factor)x is the independent variabley is the dependent variableIf b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
If the mountain is losing elevation at a rate of 5% every millennium , then it as every millennium passes, it will be 95% of the height it was in the previous millennium (as 100% - 5% = 95%)
Given:
a (initial value) = 1300 mb = 95% = 0.95x = 8 millenniaSubstituting these values into the formula:
[tex]\sf \implies y=1300(0.95)^8[/tex]
[tex]\sf \implies y=862.4467607...[/tex]
[tex]\sf \implies y=862 \ m \ (nearest \ whole \ number)[/tex]

A gumball machine contains 232323 green gumballs, 525252 red gumballs, 343434 blue gumballs, 616161 yellow gumballs, and 303030 pink gumballs. What percentage of the gumballs are red?.
Answer:
%26
Step-by-step explanation:
We can set up a proportion to find out what percentage of the gumballs are red:
[tex]\frac{525252}{232323+525252+343434+616161+303030} =\frac{x}{100}[/tex]
[tex]\frac{525252}{2020200} =\frac{x}{100}[/tex]
[tex](525252)(100)=2020200(x)[/tex]
[tex]\frac{(525252)(100)}{2020200} =x[/tex]
[tex]26=x[/tex]
Since we set up x as a fraction of 100 when writing the proportion we can say that the percentage of red gumballs is %26.

Length ×Breadth9.5(7.5)71.25cm²The area of the drawing is 71.25 square cm.
What is Area of Rectangle?The area of Rectangle is length times of width.
The actual dimensions of the rectangle are 95 m by 75 m.
The drawing is made to a scale of 1 cm to 10 m, which means that each centimeter on the drawing represents 10 meters.
Let us find the area of the drawing
First calculate the area of the rectangle in real life, and then scale it down using the ratio of 1 cm to 10 m.
The area of the rectangle in real life is:
95 m × 75 m = 7125 square meters
To scale this down to the drawing, we need to divide both dimensions by 10.
The area of the drawing is
(95 m / 10) × (75 m / 10)
= 9.5 cm × 7.5 cm
= 71.25 square cm
Therefore, the area of the drawing is 71.25 square cm.

ben exercises every 12 days and isabella every 8 days. both isabella and ben exercised today. how many days till they exercise together again?
Answer:
24 days
Step-by-step explanation:
lowest common multiple of 12 and 8 is
24
For them to exercise together again, the day must be a common multiplier of 12 and 8
12 = [tex]2^{2} . 3[/tex]
8 = [tex]2^{3}[/tex]
So, their LCM is [tex]2^{3} .3 = 24[/tex]
=> After 24 days, they will exercise together again.
The perimeter of a rhombus is 84 inches. one
diagonal is 12 inches. find the area of the
rhombus. round your answer to the nearest
hundredth if necessary.
Answer: 241.5 square inches
Step-by-step explanation:
hey hi hello whats up can someone help me with this please??........ thank you! :)
Sure!
The hundredths place is the second in a decimal.
with rounding, if the number is greater than or equal to 5, you round up, if not, you round down.
In this case we round up because 9 is bigger than 5.
So, it becomes 6.79

377 square centimeters.
363 square centimeters.
352 square centimeters.
391 square centimeters.
Answer:
377 square centimeters
Step-by-step explanation:
Formula: h(2×pi×radius) I know there's a second part but I'm doing this first.
First find the radius, in the problem it says a diameter of 10cm
Divide 10 by 2 to find the radius = 5
I'm going to use 3.14 as Pi

Which of the following expressions can be used to find the area of the kite? Select all that apply.
2 (12 × 20 × 50) + 2(12 × 20 × 10)
2 (12 × 20 × 60)
2 (20 × 50) + 2(20 × 10)
