simply:
-24d⁵z⁴/ 18d-⁵z⁴
write your answer with only positive exponents
Answer:
-24d^10/18
Step-by-step explanation:
-24d⁵z⁴/ 18d-⁵z⁴
The two z⁴ cancel out, and when dividing exponents you subract them.
d⁵-d-⁵=d^10
Put it all together and you get
-24d^10/18

A fruit bowl contains apples, oranges, and bananas. The radius of one of the oranges is 1.45 inches. What is the approximate volume of the orange? Use 3.14 for .
Answer:
12.76 in³
Step-by-step explanation:
The volume of a sphere formula is V = (4/3)πr³.
Here we use 3.14 for π and 1.45 in for r. We get:
V = (4/3)(3.14)(1.45 in)³ ≈ 12.76 in³

Answer:
x=16º
Step-by-step explanation:
The sum of angles in a triangle is 180º.
So,
39 + 125 + x = 180
Solve for x.
164 + x = 180
x = 180-164
x= 16
If angle 2 measures 75 degrees, how many degrees is angle 4?

–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
Answer: -2.3
Step-by-step explanation:
–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
–9.96 + 9.9t = 1.54 + 14.9t
-9.96 - 5t = 1.54
-5t = 11.5
t = -2.3
Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 125 millimeters, and a standard deviation of 7
millimeters.
If a random sample of 44 steel bolts is selected, what is the probability that the sample mean would be greater than 127.1 millimeters? Round your
answer to four
decimal places
Answer:
P(X > 127.1) = 0.0233
Step-by-step explanation:
We are given;
Population mean; μ = 125 mm
Sample mean; x¯ = 127.1 mm
Sample size; n = 44
Standard deviation; σ = 7 mm
Formula for test statistic is;
z = (x¯ - μ)/(σ/√n)
z = (127.1 - 125)/(7/√44)
z = 2.1/1.0553
z = 1.99
From z-table attached;
P(X > 127.1) = P(z > 1.99) = 1 - 0.97670 = 0.0233

Michael cut 1/5 from a round dessert.Isrel cut a pice from the same dissert with an angle measure of 45 degrees who cut the larger piece?
Answer:
Michael cut the lrger piece
Step-by-step explanation:
a circle has 360 degrees
360:5=72° -> michaels piece
45°<72°
Step-by-step explanation:
Michael cut 1/5 of a round dessert.
Round dessert is a circke so total angle in 360.
Now, 1/5 of 360 = 360/5 = 72
72 > 45
So Michael cut the larger piece.

In this diagram, AC and AB are
tangent to o 0. The measure of BOC
is 265º and the measure of BC is 95'.
What is the measure of CAB?
Answer:
angle CAB = 85 degrees
Step-by-step explanation:
angle CAB = 1/2(265-95)
angle CAB = 85 degrees
(2,11) and (-3,6) slope we need to find b and write equations
Answer:
Step-by-step explanation:
(2,11)(-3,6)
-3-2/6-11
-5/-5
m=1
y=mx+b
11=1(2)+b
11=2+b
b=9
y=x+9
b—> 9
Slope: 1 (The y value increases the same amount as the x.)
rearrange U=1/2KX2 make x the subject

U = potential energy of a spring at a certain position
k = the spring constant, specific to the spring, with units N/m.
x = distance the spring is stretched or compressed away from equilibrium
Potential Energy: Elastic Formula Questions:
1) A spring, which has a spring constant k = 7.50 N/m, has been stretched 0.40 m from its equilibrium position. What is the potential energy now stored in the spring?
Answer: The spring has been stretched x = 0.40 m from equilibrium. The potential energy can be found using the formula:
U = 1/2kx2
U = 1/2(7.50 N/m)(0.40 m)2
U = 0.60 N∙m
U = 0.60 J
