(2x²+6x-22) ft
Step-by-step explanation:
l = (x²+2x-16) ft
and w = (x+5) ft
the Perimeter =
2(x²+2x-16) +2(x+5)
= 2x²+4x-32+2x+10
= 2x²+6x-22

On a unit circle, the terminal point of 0 is (sqrt3/2,1/2)
What is 0?
Answer:
The measure of [tex]\theta[/tex] is 30°.
Step-by-step explanation:
In the statement, the angle has been misrepresented. The corrected statement is described below:
"On a unit circle, the terminal point of [tex]\theta[/tex] is [tex]\left(\frac{\sqrt{3}}{2}, \frac{1}{2} \right)[/tex]. What is [tex]\theta[/tex]?"
The measure of the angle ([tex]\theta[/tex]), in radians, is in standard form, that is, it is done with respect to the +x semiaxis. The measure of the angle whose terminal point is of the form [tex](x,y)[/tex] is determined by the following inverse trigonometric function:
[tex]\theta = \tan^{-1}\left(\frac{y}{x} \right)[/tex] (1)
If we know that [tex]x = \frac{\sqrt{3}}{2}[/tex] and [tex]y = \frac{1}{2}[/tex], then the measure of [tex]\theta[/tex] is:
[tex]\theta = \tan^{-1} \frac{\sqrt{3}}{3}[/tex]
[tex]\theta = 30^{\circ}[/tex]
The measure of [tex]\theta[/tex] is 30°.

Answer:
If the angle is in radians...
Area of sector =½r²¢
Where ¢ is theta.
Since Our angle is degree
We use
Area of Sector = ¢/360 x πr²
¢=theta
radius = Diameter/2
radius = 16/2 = 8m
Area = 126/360 x π x 8²
= 112π/5
=70.37
Enriques bathroom measures 6 ft. Long by 5 ft. Wide His shower is 3 feet square The title he wants to buy for the floor is sold in square feet. What is the area of the floor that he has to title
Answer:
Area of the floor is 30 square ft.
Step-by-step explanation:
Length of the floor, L = 6 ft
width of the floor, W = 5 ft
The floor is in the shape of rectangle.
The area of the rectangle is
A = Length x width
So, the area of the floor is
A = L x W
A = 6 x 5
A = 30 ft^2
After studying the growing population of a certain species of fish, Dr. Goldthwait has determined that the population will grow
in such a way that the population each year will be 27 less than the square of the previous year's population. If he introduces
this species of fish to a new environment by placing a population of 15 fish, and the population grows according to his results
which of the following recursive formulas can be used to determine the number of fish that will be in the environment in the
future? Assume that the space for the population to grow is unlimited.
OA
NEXT = Now2 - 27 starting at 15
OB. NEXT = (NOW + 27) starting at 15
OC. NEXT = now? + 27 starting at 15
OD. NEXT =
(NOW - 27) starting at 15
Answer:
OB. NEXT
Step-by-step explanation:
Find the surface area of the cylinder. Round your answer to the nearest tenth.
Answer:
62.8
Step-by-step explanation:
The formula of finding the volume of a cylinder v= pi*r^2*h
So substitute the values:
r is 2, and h is 5
v=pi*2^2*5
Then solve the equation:
v=pi*4*5
v=pi*20
v=62.8 (I multiplied 20 by 3.14, or pi)
So the answer is 62.8

Multiplying x by a number greater than 1 will stretch the parabola.
Changing x from positive to negative and vice versa reflects the parabola over the x-axis.
Find the measure of the largest angle.
Answer:
4x-7
Step-by-step explanation:
Solve for x:
180 = 44 + 3x - 11 + 4x - 7
Combine like terms: 180 = 26 + 7x
Simplify: 154 = 7x
Simplify: 22 = x
Substitute: 3(22) - 11 = 55 and 4(22) - 7 = 81
Create inequality: 44 < 55 < 81

From 1980 to 1990 the consumer price index increased from 82.4 to 130.7 if a bottle of dish soap cost 0.74 in 1980 and the price of dish soap increased at the same rate as the cpi from 1980 to 1990 by approximately how much did the price of the bottle of dish soap increase from 1980 to 1990
Answer:
$0.43
Step-by-step explanation:
Rate of increase = [(CPI in 1990 / CPI in 1980)^1/t] - 1
(130.7 / 82.4)^1/10
1.586165^0.1 = 1.047213 - 1 = 4.72%
Price of dish soap in 1990 = value in 1980 ( 1 + rate of increase)^10
0.74( 1.047213)^10 = 1.174
Price increase 1.174 - 0.74 = 0.43
What is the length of b?
does anyone know how to do this ?
Answer:
i^85 = i
A way you can solve this is divide 85 by4
The remainder is one right? that means i^85 is the same as i^1. remember, i^1 = i.
How to solve this? I have no clue and also teach me on how to solve this! Thank you!!!
Answer:
90 counterclockwise or 270 clockwise
Step-by-step explanation:
just trust me bro lolskies
====================================================
Explanation:
Through some strange formatting error, the tickmarks are not in the proper locations. They should be to the right and slightly above the letter. They should be close by, and not far away like that.
It looks like the purple figure is the image while the blue figure is the preimage. If that's the case, then we've applied a 90 degree counterclockwise rotation to go from blue to purple.
Notice how angle AQA' is 90 degrees as shown by the green segments in the diagram below. So are BQB' and CQC' and DQD' as well.
We could also rotate the blue figure 270 degrees clockwise to arrive at the same purple image. Note how 90+270 = 360 which is a full circle.
Tatiana is playing a video game. She earns 25 points when she completes Level 1. Each time she completes a level, she earns three times as many points as the previous level.
How many points will Tatiana earn when she completes Level 7?
Answer:
18,225
Step-by-step explanation:
L1=25
L2=75
L3=225
the pattern is (25)* 3^(n-1)
L1=3^0*25 = 25
L2=3^1*25 = 3* 25 = 75
L3=3^2*25 = 9* 25 = 225
.
.
L7=3^6*25 = 729* 25 = 18,225

The time t required to drive a certain distance varies inversely with the speed r. If it takes 4 hours
to drive the distance at 50 miles per hour, how long will it take to drive the same distance at 40
miles per hour?
Answer:
1.78 hours
Step-by-step explanation:
If t varies inversely with the speed, the formula for that is t= \frac{k}{r} . If t = 2 and r = 40, then we can solve for k, the constant of variation. Multiply both sides by 40 to get k = 80. Now we need to find the value for t when r = 45. Using the k value we just solved for, we will fill in the equation as t= \frac{80}{45} for a t value of about 1.78 hours

Step-by-step explanation:
For consumers making purchases online, 60% have devices made by Apple, 85% own a smartphone, and 75% use Venmo. Also, out of the smartphone users, 80% use Venmo. Assume that having a device made by Apple and owning a smartphone are independent. A consumer who makes purchases online is selected at random, what is the probability they have an Apple device or own a smartphone (or both)? Enter your answer as a decimal to two places, and include the leading zero. For example, 0.12 would be a valid format.
Answer:
The probability that a customer selected at random has an Apple device or own a smartphone or both is 0.94
Step-by-step explanation:
The percentage of costumers that have a device made by Apple = 60%
The percentage of customers that own a smartphone = 85%
The percentage of customers that use Venmo = 80%
The percentage out of the smartphone users that use Venmo = 80%
The probability both independent events A and B occurring = P(A) × P(B)
The exclusive probability of A or B occurring P(A XOR B) = P(A) + P(B) - 2 × P(A ∩ B)
Therefore, the probability of A or B or both occurring is given as follows;
P(A or B or Both) = P(A) + P(B) - 2 × P(A ∩ B) + P(A) × P(B)
Where A represent the percentage of costumers that have a device made by Apple and let B represent the percentage of users that have a smartphone, we have;
P(A or B or Both) = 0.6 + 0.85 - 2×0.6×0.85 + 0.6 × 0.85 = 0.94
Therefore, the probability that a customer selected at random has an Apple device or own a smartphone (or both), P(A or B or Both) = 0.94

Step-by-step explanation:
according order 15 , 19,22, 24,26,28,30,32,32. answer is 26
Answer:
Hello There!!
Step-by-step explanation:
26 is the median as you order the numbers smallest to largest.Therefore,it is 15,19,22, 24, 26,28,30,32,32 and the amount of numbers are odd so the median is the middle number.If it was even the two middle numbers would be added together and then divided by 2.
hope this helps,have a great day!!
