A Dilation has a center (0,0). Find the image of this point for the given scale factor: P (2-4); D 0.5 (P)
Answer:
(1, -2)
Step-by-step explanation:
The dilation that has a center of (0, 0) means that you would multiply each number in your coordinate point by your given scale factor.
For your given point (2, -4) with a scale factor of 0.5:
2 times 0.5 = 1
-4 times 0.5 = -2
Therefore your new point will be (1, -2).
using the triangle 45o -45o -90o theorem solve this triangle. please
Answer:
k = 24·√2
Step-by-step explanation:
Given that the angles of the triangle are 45° by 45 by 90°, we have;
The given right triangle = An isosceles right triangle by two angles being equal
The given angle of the right triangle = 90°
The given leg of the right triangle = 24
For an isosceles right triangle, both legs are equal, therefore;
The length of the other leg of the right triangle = 24
By Pythagoras theorem, the measure of the side opposite the 90° side, 'k', is given as follows;
k² = (One leg length)² + (The other leg length)²
∴ k² = 24² + 24² = 1152
k = √1152 = 24·√2 ≈ 33.94.

What is the volume of the composite figure? Explain your work. A complete answer should include how you broke up the figure, which numbers you multiplied to find the volume. You may want to use the formula for volume to find the solution.
Answer:
[tex]15,000\:\mathrm{mm^3}[/tex]
Step-by-step explanation:
The composite figure consists of a square prism and a trapezoidal prism. By adding the volume of each, we obtain the volume of the composite figure.
The volume of the square prism is given by [tex]V=s^2\cdot h[/tex], where [tex]s[/tex] is the base length and [tex]h[/tex] is the height. Substituting given values, we have: [tex]V=14^2\cdot 30=196\cdot 30=5,880\:\mathrm{mm^3}[/tex]
The volume of a trapezoidal prism is given by [tex]V=\frac{b_1+b_2}{2}\cdot l\cdot h[/tex], where [tex]b_1[/tex] and [tex]b_2[/tex] are bases of the trapezoid, [tex]l[/tex] is the length of the height of the trapezoid and [tex]h[/tex] is the height. This may look very confusing, but to break it down, we're finding the area of the trapezoid (base) and multiplying it by the height. The area of a trapezoid is given by the average of the bases ([tex]\frac{b_1+b_2}{2}[/tex]) multiplied by the trapezoid's height ([tex]l[/tex]).
Substituting given values, we get:
[tex]V=\frac{14+24}{2}\cdot (30-14)\cdot 30,\\V=19\cdot 16\cdot 30=9,120\:\mathrm{mm^3}}[/tex]
Therefore, the total volume of the composite figure is [tex]5,880+9,120=\boxed{15,000\:\mathrm{mm^3}}[/tex] (ah, perfect)
Alternatively, we can break the figure into a larger square prism and a triangular prism to verify the same answer:
[tex]V=30^2\cdot 14+\frac{1}{2}\cdot10\cdot 16\cdot 30=\boxed{15,000\:\mathrm{mm^3}}\checkmark[/tex]

A box contains 12 balls of which 5 are red, and 7 are blue. If 4 balls are drawn from the box, in how many ways can this be done if 1 is red and 3 are blue?
Answer:
175 ways
Step-by-step explanation:
5 balls are red, and 7 balls are blue making a total of 12 balls.
4 balls are drawn from the box,
1 ball is red and 3 balls are blue out of the 4 drawn from the box.
We have to choose 1 ball from 5 red balls and 3 blue balls from 7 blue balls.
Since the order is not essential we use combinations to find out
5C1 * 7C3= 5*35 = 175 ways

What is the surface area of the ice cream
cone? (Hint: The top of the cone is open and
not included in the surface area.)
mm
Cone Surface Area =
Answer:
[tex]13194.7\ mm^2[/tex]
Step-by-step explanation:
The total surface area of a cone is given by:
Surface area = [tex]\pi r(r+\sqrt{h^2+r^2} )[/tex]
where r is the radius of the cone, h is the height of the cone, l is the length of the cone = [tex]\sqrt{h^2+r^2}[/tex]
Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:
[tex]Surface \ area=\pi r(\sqrt{h^2+r^2} )=\pi rl\\\\Surface \ area=\pi (30\ mm)(140\ mm)=13194.7\ mm^2[/tex]

You are a manager in one of the branches of a restaurant. The area manager assigned
you to analyze the statistical data of the ages of the customers who eat in your
restaurant. From the survey forms, the following are the summary of their evaluations:
Age - - - - - - - No. of Customers
16–20 - - - - - -32
21–25 - - - - - -40
26–30 - - - - - -15
31–35 - - - - - - 29

Using the given data, determine how spread out the ages of the customers are using
measures of variability. Find out what ages fall within one standard deviation from the
mean. Knowing this, what range of ages or what age group should the restaurant give
more focus on, and what products do you think should the restaurant come up with to
generate higher sales? Submit a typewritten report detailing your answers, solutions, and
explanations to these questions.

What is the value of x?
Answer:
it's 19 degrees because it's a 90 degree angle
Answer:
19 degrees
Step-by-step explanation:
90-71=is 19 because it is a 90 degree angle.
What is the value of X?
Answer:
x=20
Step-by-step explanation:
First, find LJ
Angle L = 60 (180 - 30 - 90)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(L)=adj/hyp
cos(60)=LJ/40√2
LJ = cos(60)*40√2
LJ = 20√2
Now you can use LJ to find x. You also know the value of each angle, 45
x=20√2⋅cos(45)
x=20

What is the value of the expression below?
Answer:
7
Step-by-step explanation:
When you are raising a power to a power, you can multiply them:
[tex](49^3)^{\frac{1}{6}}=49^{3*\frac{1}{6}}[/tex] = [tex]49^{\frac{3}{6}}[/tex] = [tex]49^{\frac{1}{2}}[/tex]
When raising a number to the power of 1/2, you are basically finding the square root of the number:
[tex]49^{\frac{1}{2}}[/tex] = [tex]\sqrt{49}[/tex] = 7

Now we have to evaluate,
10/3 ÷ 20
Since we know that,
To divide two fractions,
Follow the procedures below when splitting two mixed fractions. Transform the mixed fraction into the incorrect fraction. Now multiply the first and second fractions by the reciprocal of the second fraction (i.e., divisor).
Therefore,
10/3 x 1/20 = 3/2
