Find the following
(u•w)(2)=
(w•u)(2)=
Step-by-step explanation:
substitute 2 into x
1. (u ○ w)(2)
u(w(x))
= 4(-5x+1)+2
= 4(-5.2+1)+2
= 4(-9)+2
=-34
2. (w ○ u)(2)
w(u(x))
= -5(4x+2)+1
= -5(4.2+2)+1
= -5(10)+1
= -49

Gina buys a car for $13,500. The value is expected to depreciate by 15% per year.
Write an exponential function to model the value of the car. When will the value
fall below $3000?
Answer:
the value will fall below $3000 in the 7 th year because :
Step-by-step explanation:
15% of 13500 is 2025
On subtracting 2025 from 13500 every time we can see that the value keeps dropping.
So, we will get $3375 in year 6 and in year 7 we will get $1350 by subtracting 2025 from 3375.
Hence we will get 1350 at the 7th year.
After 6.79 years, the car's value will drop below $3,000.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Now, The following is a representation of the exponential function to model the car's value:
V(t) = 13500 (1 - 0.15)ⁿ
V(t) = 13500(0.85)ⁿ
Here, V(t) denotes the car's worth at time n in years, and 0.85 denotes the annual depreciation rate of 15%.
Hence, The following equation can be put up to determine when the car's value will drop below $3,000:
13500(0.85)ⁿ = 3000
As we solve for n, we obtain:
n = (log(3000/13500)/log(0.85))
n = 6.79
So, after roughly 6.79 years, the car's value will drop below $3,000.

The calories I burn walking can be modeled by the function y = 5x + 100,
with x representing the number of minutes spent walking. How many
calories would I burn if I walked for 75
minutes?
Answer:
X=75
Y=5X+100
Y=5*75+100
Y=375+100
Y=475
Therefore, you burnt 475 calories if you walked for 75 minutes

B. r = 6V – 7
O c. r= = v
OD. r= 16V (11)
Answer:
A) r=∛(6v)/[tex]\pi[/tex]
Step-by-step explanation:
v=1/6[tex]\pi[/tex]r³
v÷1/6=[tex]\pi[/tex]r³
(when dividing by a fraction, invert and multiply)
6v=[tex]\pi[/tex]r³
6v÷[tex]\pi[/tex]=r³
(6v)/[tex]\pi[/tex]=r³
take the cube root of both sides

A consulting firm has bid on two projects, A and B. The probability of landing A is 0.70. The probability of landing B is 0.60. The probability of landing both is 0.50.
What is the probability of landing A given it lands B?
Given:
The probability of landing A is 0.70.
The probability of landing B is 0.60.
The probability of landing both is 0.50.
To find:
The probability of landing A given it lands B.
Solution:
We have,
[tex]P(A) = 0.70[/tex]
[tex]P(B) = 0.60[/tex]
[tex]P(A\cap B) = 0.50[/tex]
The probability of landing A given it lands B is
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{0.50}{0.60}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{5}{6}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=0.8333...[/tex]
[tex]P\left(\dfrac{A}{B}\right)\approx 0.83[/tex]
Therefore, the probability of landing A given it lands B is about 0.83.

Answer:
she needs to put in 5 more cups of sugar.
Step-by-step explanation:

Written in terms of pi how many times greater is the area than the circumference
Answer:
If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi. Circumference = 18 pi Area = 81 pi Area is 4.5 times greater than the circumference. The answer is C.
Answer:
Those two quantities are incommensurate, you can't compare them. The circumference is a length and the area is an area. There is no way to compare the two.
Now if you're talking about the formula Area = circumference squared over 4 times Pi, and if you're just going to go with the numerical values of Area and circumference, then there is an answer.

Answer:
The measure of angle BED is 82°
Step-by-step explanation:
The angles of a triangle, all together, equal 180°.
Angle B and D are the same and angle B is 49° so angle D is also 49°.
You add 49 to 49 which equals 98, and subtract 98 from 180 to find out what angle E is.

You invested S3000 between two accounts paying 4% and 8% annual interest respectively if the total interest eamed for the year was S520 how much was invested at each ratė? was invested at 4% and so was invested at se
Answer:
Even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
Step-by-step explanation:
Given that you invested $ 3000 between two accounts paying 4% and 8% annual interest respectively, to determine how much was invested at each rate if the total interest eamed for the year was $ 520, the following calculation must be performed:
3000 x 0.04 + 0 x 0.08 = 120
1500 x 0.04 + 1500 x 0.08 = 180
3000 x 0.08 + 0 x 0.04 = 240
Thus, as can be seen, even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
