Answer:
1/ 3^6
Step-by-step explanation:
We know that a^b / a^c = a^(b-c)
3^-7 / 3^-1 = 3^(-7 - -1) = 3^(-7+1) = 3^(-6)
We know that a^ -b = 1/ a^b
3^-6 = 1/ 3^6
What is the simplest radical form of the expression? (8x5y3)23
This may be incorrect, so sorry if it is! The answer I got is 2760y.

Marlon buys a sweater for $28 that has $17 off its usual price in sale. Write an equation to describe the cost of the sweater in the sale compared with its usual price. Then solve the equation to find the usual price of the answer.
x - 17 = 28
so
28 + 17 = x
28 + 17 = $45
so
x = $45
(I'm pretty sure)

In circle D with m \angle CDE= 76m∠CDE=76 and CD=13CD=13 units find area of sector CDE. Round to the nearest hundredth.
Answer:
112.03sq. units
Step-by-step explanation:
The area of a sector = theta/360 * πr²
The area of a sector = 76/360 * 3.14 * 13²
The area of a sector = 76/360 * 530.66
The area of a sector = 40,330.16/360
The area of a sector = 112.03sq. units
This gives the area of the sector

6. Find JL.
Please and thank you. 5x-16=3x+4
Answer:
JL = 68
Step-by-step explanation:
JM = ML
Hence, 3x + 4 = 5x - 16
Subtract 3x from both sides
4 = 2x - 16
Add 16 to both sides
20 = 2x
Divide both sides by 2
10 = x
Now we want to find JL
Note that JL = JM + ML
JM = 3x + 4 and x = 10
Substitute 10 for x
3(10) + 4
Multiply
30 + 4
Add
JM = 34
Because JM = ML
We simply multiply 34 times 2 to find the length of JL
34 * 2 = 68
JL = 68
choose the pair of sets which is equivalent
Answer:
set ={Sunday,Monday,Tuesday,Wednesda,Thursda,Friday, Saturday} and set={1,2,3,4,5}
Step-by-step explanation:
To be equivalent, the sets should have the same cardinality.Find d^2y/dtheta^2 if y=sin^5
Answer:
20 sin³O. cos²O - 5sin⁵O
Step-by-step explanation:
y = sin⁵O
Using the Chain Rule
dy/dO = 5 sin⁴O cosO
Using the Product / Chain rules:
d²y/dO² = 20 sin³O.cosO . cos O+ 5 sin⁴O * - sin O
= 20 sin³O. cos²O - 5sin⁵O

OladipoSeun♡˖꒰ᵕ༚ᵕ⑅꒱how much work is done when you lift an object that weighs 150 N to a height of 5 meters
Answer:
Work done = 150 x 5 = 750 J
Step-by-step explanation:
Work done is the measure of energy transferred to an object when a force is added causing the object to move a distance in the direction of the force.
The equation for work done is force time the distance and is measured in Joules. Therefore the formula is W = F x D
work done (W) is measured in joules (J)
force (F) is measured in newtons (N)
distance (d) is in the same direction as the force and is measured in
metres (m)
W = F x D
w = 150 x 5
W = 750 J

How do you ratify the denominator for 2/ 2(sqrt2)? When I multiply by sqrt2/sqrt 2 I'm still left with a radical in the denominator.
Answer: [tex]\dfrac{\sqrt{2}}{2}[/tex]
Step-by-step explanation:
Given
The fraction is [tex]\dfrac{2}{2\sqrt{2}}[/tex]
Making denominator a number, multiply and divide by [tex]\sqrt{2}[/tex]
[tex]\Rightarrow \dfrac{2}{2\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}\\\\\Rightarrow \dfrac{2\sqrt{2}}{2\sqrt{2}\times \sqrt{2}}=\dfrac{2\sqrt{2}}{2\sqrt{2\times 2}}\\\\\text{cancel out the common term 2}\\\\\Rightarrow \dfrac{\sqrt{2}}{2}[/tex]

Answer:
0.5x+20=0.25x+30, m=40
Step-by-step explanation:
Blue: y=0.5x+20
Red: y=0.25+30
We’re looking for where the y (cost) is equal, so we can set the two equations to each other:
Isolate x:
0.5x+20=0.25x+30
0.5x+20-20=0.25x+30-20
0.5x=0.25x+10
0.5x-0.25x=0.25x+10-0.25x
0.25x=10
x=40
m= 40

The organizers want the zip line to have two platforms (towers / anchors). The first platform (on the higher ground) should be about 50 m away from the second platform. The slope length from the top of platform one to the top of platform two should be about 70 m. What would be the angle of depression from platform one to two to the nearest degree?
Answer:
The angle if depression is 44.4 degree.
Step-by-step explanation:
horizontal distance, d = 50 m
slope length, L = 70 m
The angle of depression is given by
[tex]cos\theta=\frac{d}{L}\\\\cos \theta = \frac{50}{70}\\\\cos \theta = 0.714\\\\\theta = 44.4^o[/tex]
Un político Envía un cuestionario a sus votantes para determinar sus intereses acerca de 6 asuntos de importancia nacional: desempleo, medio ambiente, impuestos, tasas de interés, defensa nacional y seguridad social. Los votantes deben seleccionar cuatro asuntos de interés personal y colocarlos en orden: o un número1, 2, 3 0 4 después de cada asunto para indicar el grado de interés, donde 1 indica el mayor interés y 4 el menor interés ¿ En cuantas formas se puede responder al cuestionario.
Answer:
El cuestionario puede ser respondido de 360 formas diferentes.
Step-by-step explanation:
Dado que un político envía un cuestionario a sus votantes para determinar sus intereses acerca de 6 asuntos de importancia nacional: desempleo, medio ambiente, impuestos, tasas de interés, defensa nacional y seguridad social, y los votantes deben seleccionar cuatro asuntos de interés personal y colocarlos en orden 1, 2, 3 y 4 después de cada asunto para indicar el grado de interés, donde 1 indica el mayor interés y 4 el menor interés, para determinar en cuantas formas se puede responder al cuestionario se deben realizar los siguientes cálculos:
6 x 5 x 4 x 3 = X
30 x 4 x 3 = X
120 x 3 = X
360 = X
Por lo tanto, el cuestionario puede ser respondido de 360 formas diferentes.
A class of 20 students is visiting the fair today. Each student is 16 years old or younger and will participate in either the Pie Eating Contest or the Chili Cookoff. If all 20 students joined the same event, how would the shape of the histogram change compared to the original?

If θ is in standard position and -180° < θ <-90°, then θ terminates in Quadrant _____.
Answer:
Quadrant III
Step-by-step explanation:
-180° is a 180° rotation clockwise, which will end up between Quadrant II and III. -90° is a 90° rotation clockwise, which will end up between Quadrant III and Quadrant IV. The range of possible angles are contained in Quadrant III, in conclusion.

Find the value of x.
====================================================
Work Shown:
secant angle = (far arc - near arc)/2
angle BGC = (arc BC - arc AD)/2
40 = (115 - x)/2
2*40 = 115-x
80 = 115-x
115-x = 80
-x = 80-115
-x = -35
x = 35
For more information, you can search out "secant angles" and it should go over how the formula is set up and why it works.
W is the midpoint of VX and Z is the midpoint of VY . If XY=p and WZ=p–30, what is WZ?

Esmerelda flips a coin and draws a card. What is the possibility that she gets “heads” and a black card?
Answer:
1/4
Step-by-step explanation:
The probability of flipping a coin and landing a heads is 1/2. Their are 26 black cards in a standard deck of 52 cards- 26/52 (1/2). Multiply the fractions to get the probability.
1/2 * 1/2 = 1/4
