The shape shown on the coordinate plane is rotated about the y-axis.
What is the shape of the solid created by the rotation?
Answer:
Cone, radius = 4, height = 7
Step-by-step explanation:
The point (4, 0) will spin around the y-axis, forming the base of the cone. The point (0, 7) will not move--it's point of the cone.
The expression cube root of x^2/square root of x
can be rewritten as
what the perimeter and area of this shape?

Find the value of D. A 75 B 56 C 47 D 30
Step-by-step explanation:
75
Option B is correct. The measurement of the angle m in the circle given is 56degrees
Geometry deals with the measurement of properties of lines, solids, and angles.
The diagram given in the question is a circle. To get the value of d, we will use one of the circle theorems which states;
The angle at the vertex is equal to half the sum in its intercepted arcs as shown:[tex]75=\frac{1}{2} (m\angle d - 94)[/tex]
Cross multiply
[tex]75 \times 2 = m \angle d - 94\\150=m \angle d +94\\m \angle d = 150 - 94\\m \angle = 56^0[/tex]
Hence the measurement of the angle m is 56degrees

Point G is (-8,6) Point J is a reflection of point G and is reflected across the x axis what are the coordinates of point J?
Answer:
(-8, -6)
Step-by-step explanation:
Given the Point G is (-8,6) if Point J is a reflection of point G and is reflected across the x axis, to get the coordinate of point J, we will negate the y coordinate while retaining the x coordinate value
J = (-8, -(6))
J = (-8, -6)
Hence the required coordinate of J is (-8, -6)

Find the sides marked with letters, all lengths are given in centimeters.
Answer:
Length of side LM = 9 units
Length of side AC = 9 units
Length of side LN = 15 units
Step-by-step explanation:
Given:
In Δ LMN
Length of side LM = m
Length of side LN = a
Length of side MN = 15
In Δ ABC
Length of side AB = 6
Length of side BC = 9
Length of side AC = m
Find:
Length of all missing sides
Computation:
We know that both triangle are similar using AA rule
So,
Length of side LM / Length of side MN = Length of side AB / Length of side BC
Length of side LM / 15 = 6 / 9
Length of side LM = [6 x 15] / 9
Length of side LM = 90 / 9
Length of side LM = 9 units
Length of side LM = Length of side AC = m
Length of side AC = 9 units
Length of side MN / Length of side LN = Length of side BC / Length of side AC
15 / Length of side LN = 9 / 9
Length of side LN = 15 units

12 snack bars together weigh 1 lb. 4 oz. If there are 16 oz. in a lb. and 453.6 g in a lb., how many grams does
each bar weigh? Round your answer to the nearest hundredth.
Answer:
567g
Step-by-step explanation:
Each bar weighs 1 lb 4 oz. Since a pound is 16 oz, 4 oz is 1/4 or .25 lb.
1.25 x 453.6
567
Each bar weighs 567g.
Use the distributive property to write an expression that is equivalent to the expression 4(12 - 3x) + 6 for all values of x.
Answer:
-12x + 54
Step-by-step explanation:
Using the distributive property, distribute 4 to the terms in the parentheses:
4(12 - 3x) + 6
Multiply 12 and -3x by 4:
48 - 12x + 6
Add like terms:
-12x + 54
So, the answer is -12x + 54
9514 1404 393
Answer:
54 -12x
Step-by-step explanation:
The factor outside parentheses multiplies each term inside.
4(12 -3x) +6 = 4(12) +4(-3x) +6
= 48 -12x +6
= 54 -12x
Cheryl bought a shirt for $42 and sweater for$30. Write a numerical expression that represents the change Cheryl received from four $20 bills
Answer:
[tex]Change = \$8[/tex]
Step-by-step explanation:
Given
[tex]Bills = $20\ bills[/tex] (4)
[tex]Shirt = \$42[/tex]
[tex]Sweater= \$30[/tex]
Required
The change
First, we determine the amount paid,
To do this, multiply the number of bills by the worth of each bill.
So, we have:
[tex]Amount = 4 * \$20[/tex]
[tex]Amount = \$80[/tex]
Next, calculate the worth if item bought
[tex]Items = \$42 + \$30[/tex]
[tex]Items = \$72[/tex]
Subtract the items from the amount to get the change.
[tex]Change = \$80 - \$72[/tex]
[tex]Change = \$8[/tex]

Answer:
y = [tex](\frac{1}{2})^{-x} +4[/tex]
Step-by-step explanation:
In order to achieve the following transformation we need to do the following. To get the graph to be reflected accross the y-axis we need to change the sign of the x variable. Since the x-variable in this scenario is a positive we would change it to a negative. Next, we want to shift the graph 4 units up. To do this we simply need to add 4 to the entire equation. This would result in the following equation.
y = [tex](\frac{1}{2})^{-x} +4[/tex]
Both of these graphs can be seen in the image below.

Example 0.8kilometer what till ut b in minutes woukd u times by 70
Answer:
It is not possible
Step-by-step explanation:
Given
0.8km
Required
Convert to minutes
In conversion, only units of the same metric can be converted.
i.e.
You can convert meters to miles (they both measure distance)
You can convert seconds to hours (they both measure time)
You can convert kilogram to pounds (they both measure weight)
But in the given question, you attempt to convert from distance to time.
This is not possible, because time and distance are different measurements
If f(x) = 2x+ 1, then f(3) =
i cant really seem to understand how to work it out.
Answer:
f(3) = 7
Step-by-step explanation:
f(x) = 2x + 1
f(3) = 2(3) + 1
f(3) = 6 + 1
Substitute the 3 in for x.
f(3) means that x is equal to 3.
This just means we substitute the value of 3 into the f(x) = 2x+ 1 to get
f(x) = 2(3)+ 1,
f(3) = 2(3)+ 1,
f(3) = 6+ 1,
f(3) = 7

The selected choices are almost correct.
The curve of intersection of a plane and a cylinder can be a circle or ellipse. It cannot be a parabola.
The only straight lines on a cone are the ones that are the lines through the a.pex revolving around the axis of symmetry. There are no parallel lines, so a rectangular cross section is impossible.
Hannah claims that people who live in southern states spend 9 hours more per week outside than do people in northern states. She selects a random sample from each group. The mean number of hours per week that people in southern states spent outside is 18.6, and the mean number of hours per week that people in northern states spent outside is 14.4. A 99 percent confidence interval to estimate the difference in population means (southern minus northern) is (0.4,8.0).
Answer: Hello your question is incomplete below is the missing part
Which of the following statements about Hannah’s claim is supported by the interval?
A) Hannah is likely to be incorrect because the difference in the sample means was 18.6−14.4=4.218.6−14.4=4.2 hours.
B) Hannah is likely to be incorrect because 9 is not contained in the interval.
C)The probability that Hannah is correct is 0.99 because 9 is not contained in the interval.
D)The probability that Hannah is correct is 0.01 because 9 is not contained in the interval.
E)Hannah is likely to be correct because the difference in the sample means (18.6−14.4=4.2)(18.6−14.4=4.2) is contained in the interval.
Answer : Hannah is likely to be incorrect because 9 is not contained in the interval. ( B )
Step-by-step explanation:
The statement that is supported by the interval in Hannah's claim is that
Hannah is likely to be incorrect because 9 is not contained in the interval.

convert 2 miles to centimeters.
express your answer in scientific notation
Answer:
To convert miles to cm, multiply the mile value by 160934.4. For example, to find out how many centimeters there are in 2 miles, multiply 2 by 160934.4, that makes 321868.8 cm in 2 miles.
multiply 2 by 160934.4, which is
321868.8 cm in 2 miles.
How do you change miles into centimeters?
To convert a mile to a centimeter, multiply the length by the conversion ratio. The length in centimeters is equal to the miles multiplied by 160,934.4.
The distance in km is equal to the distance in miles multiplied by 1.609344. Since 1 mile is equal to 1.609344 km, that's the conversion ratio used in the formula.
