Answer:
7 ft
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr
The curved portion of a semicircle will be ...
C/2 = (2πr)/2 = πr
The straight portion of the semicircular shape will be the diameter, or 2r. That means the total perimeter of a semicircular shape is ...
P = πr +2r = r(π+2)
Then the radius is ...
r = P/(π+2) = (35.98 ft)/(3.14+2) = 7 ft
The radius of the patio is 7 ft.
Factor w2 + 3w+w + 3 by grouping,
Answer:
(w+3)(w+1)
Step-by-step explanation:
In w^2 + 3w+w + 3,
we group it so that it looks like (w^2+w) + (3w+3)
Then we factor so that is w(w+1) + 3(w+1).
Distributive property(converse) allows us to simplify to (w+3)(w+1)
What is the range of the function y=Vx+5?
Answer:
[tex]y\geq-5[/tex]
Step-by-step explanation:
Because [tex]x+5[/tex] cannot be negative, then [tex]x=-5[/tex] has to be the absolute minimum of the function given its domain. Therefore, all real values of x greater than -5 are all values that exist in the function's range.
5. Linda earns $95 per day. If she works of a day, how much will she earn?
Answer:
95 Dollars
Step-by-step explanation:
95 dollars because she earns 95$ per day and it says "of a day" so it would have to be 95*1, and 95*1 is 95 and it asks how much she earns as in money so it is 95 dollars.

Wendy has $27 to buy seed for her birdfeeders. Each bag of seed costs $5.
How many bags of seed can she buy? Do not include units in your answer.
Answer here
SUBMIT
Answer:
5
Step-by-step explanation:
If Wendy has $27 to buy seeds, and each seed bag costs $5, then:
5 · 5 = 25
5 · 6 = 30
27<30
27>25
So, Wendy is able to buy 5 bags and remain with 2 dollars.
Question One:
An Internet-based company that sells discount accessories for cell
phones often ships an excessive number of defective products. The
company needs better control of quality. Suppose it has 20 identical
car chargers on hand but that 5 are defective. If the company decides
to randomly select 10 of these items, what is the probability that 2 of
the 10 will be defective?
Probability that 2 of the 10 chargers will be defective =0.35
Number of ways of selecting 10 chargers from 20 chargers is 20C10
20C10 = 184756
Number of ways of selecting 10 chargers from 20 = 184756
Number of ways of selecting 2 defective chargers from 5 defective chargers = 5C2
5C2 = 10
Since 2 defective chargers have been chosen, there remains 8 to choose
Number of ways of selecting 8 good chargers from 15 remaining chargers = 15C8
Number of ways of selecting 8 good chargers from 15 remaining chargers = 6435
Probability that 2 of the 10 will be defective =
(10x6435)/184756
Probability that 2 of the 10 will be defective = 64350/184756
Probability that 2 of the 10 chargers will be defective =0.35

Consider f and c below. f(x, y) = x2 i + y2 j c is the arc of the parabola y = 2x^2 from (−1, 2) to (0, 0)
(a) find a function f such that f = ∇f.
f(x, y) =
(b) use part (a) to evaluate c ∇f · dr along the given curve C.
(a) If there is a scalar function f(x, y) such that ∇ f(x, y) = x² i + y² j, then
∂f/∂x = x²
∂f/∂y = y²
Integrating both of these equations with respect to x and y (respectively) gives
f(x, y) = 1/3 x³ + g(y)
f(x, y) = 1/3 y³ + h(x)
Differentiating with respect to the other variable gives
∂f/∂y = g'(y) = y²
∂f/∂x = h'(x) = x²
so it follows that
f(x, y) = 1/3 x³ + 1/3 y³ + C
for some constant C.
(b) By the gradient theorem,
[tex]\displaystyle \int_C \nabla f \cdot d\vec r = f(0,0) - f(-1,2) = \boxed{-\dfrac73}[/tex]
Example 8: Over the track-and-field season, the height Fred cleared in the high jump increase from 1.81 m to 1.96 m. a) Find Fred's percent increase in height. W b) What final height would Fred have to clear for a 20% increase in height over the track-and-field season?
Answer:
a. about 8.3%
b. 2.172 m
Step-by-step explanation:
a. 1.81 * x = 1.96
x = 1.083
Percent increase is approximately 8.3%
b. 1.81 * 1.2 = x
x = 2.172 m

Answer:
3 x 9 = 3 x (5 + 4)
= 15 + 12
= 27
Step-by-step explanation: First you split 9 into 2 parts and ask what plus what equals 9? 5 + 4 = 9 so you got the first equation 3 x (5 + 4).
Then 3 x 5 = 15 and 3 x 4 = 12 so you got the equation 15 + 12 = 27

Alec invested $1500 in an account with annually compounded interest. The account earns 4% annual interest. How much will Alec have in his account after 4 years?
Answer:
He will have $1,754.79 in his account after 4 yearsStep-by-step explanation:
We can use the compound interest formula to find how much money he will have after 4 years:
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex] ;
where
A= final amount
P= initial amount
r= interest rate
n= number of times interest applied per time period
t= number of time periods elapsed,
so from the given information, we know that 1500 is our initial amount, so P= 1500.
Annual interest means once a year, so n= 1, and the interest rate is 4%, so r= 4% or 0.04
and we are asked to find the amount in his account after 4 years, so t= 4
Now, all we need to do is plug in these values for each of the variables and solve.
[tex]A= 1500(1+\frac{0.04}{1} )^{(1)(4)}[/tex]
and we get
A= $1,754.79
