Answer:
rounded to- 7.07
Step-by-step explanation:
The formula for area of a circle is 
do you need to find the radius by divided the diameter by two, you get 1.5
You then plug in 1.5 into the formula and solve
Answer:
A, B, D are true.
Step-by-step explanation:
Given : Graph
To find :Which of these statements are true.
Solution : We can see from graph it is exponential graph .
A vertical shift is when the graph of the function is moved up or down a fixed distance,
Since , both are shift and flipped.
We can see both graph are not touching the line so, both has exactly one asymptote.
Therefore, A, B, D are true.
Let assume x be the sale price
A clothing store advertises that it is having a 25% off sale.
The sale price with 25% discount is f(x) = sale price - 25% of sale price
f(x)= x - 0.25x = 0.75x
For one day only, the store advertises and additional savings of 10%.
The sale price with 10% discount is g(x) = sale price - 10% of sale price
g(x)= x - 0.10x = 0.90x
Use composition function
g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x
That is 0.675/100 = 67.5%
The total percent discount = 100% - 67.5% = 32.5%
what would be the sale price of a $40 sweater?
Here sale price x= 40
So we plug in 40 for x
g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27
The sale price of sweater = $27
Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2
How to simplify:
9+(-2) would be just 9 - 2 = 7 -2 would 5
The answer is 5
Hope this helps
