Triangle DEF, shown below, is reflected over the y-axis to form triangle D'E'F'. What are
the coordinates of F'?
(4,6)
(6,4)
(-4, -6)
(-6, -4)

Answer:

volume of cyclinder=πr²h

=3.14×2²×3=37.68cm³

rectangular prism volume=6×5×7

=210cm³

total volume=37.68+210=247.68cm³

Step-by-step explanation:

1) Cylinder

d = 4 cm

h = 3 cm

r = d : 2

= 4 : 2

= 2

= 3.14 × 2² × 3

= 37.68 cm³

2) Rectangular prism

l = 6 cm

w = 5 cm

h = 7 cm

= 6 . 5 . 7

= 210 cm³

3) Total Volume

= 37.69 + 210

= 247.68 cm³

Step-by-step explanation:

Answer:

Area is always multiplication. 3*4= 12. Area equals 12 feet.

Step-by-step explanation:

There is probably an equation specific to the base (the parallelogram)- use that formula to plug in the numbers to multiply that give you the area.

Answer:

37 degrees

Step-by-step explanation:

A triangle has to be 180 degrees so you do 53+90 (because it is a right triangle) equals 143

then do 180-143 to get your final angle of 37

Answer:

37 degrees

Step-by-step explanation:

The degrees of a triangle will add up to equal 180 degrees. A right angle will always be equal to 90 degrees.

Set up an equation:

Variable x = degrees of the acute angle

90 + 53 + x = 180

143 + x = 180

143 - 143 + x = 180 - 143

0 + x = 37

x = 37

the equation would be no solution if the sides are equal numbers with the same slope and do not intersect.  if you plug in a random number such as 7 for x you would get 16 = 8. always making the numbers parrallel

Answer:

Sample response: The Smith family has 2 choices to make, color and style. By the fundamental counting principle, the product of the number of choices of color and style must equal 8. So, there could be 1 color and 8 style choices, 2 colors and 4 styles, 4 colors and 2 styles, or 8 colors and 1 style.

Answer:

109.75

Step-by-step explanation:

first, separate the floor into 3 different rectangles to calculate the area and then add them together.

area of rec=L*B

rec 1: 8.5*6=51

rec 2: (9.5-5)*(13.5-5-6)=11.25

rec 3:5*9.5=47.5

Then:

51+11.25+47.5=109.75

Answer:

this question answer is 1500cm^3

The product  complex number is  z1z2 = r1r2[cos (θ1+θ2) + isin (θ1+θ2)]

[tex]Z_1\times Z_2= r_1(cos \theta_1 + isin \theta_1) \times r_2(cos \theta_2 + isin \theta_2)[/tex]

r-radius/radii

m-modulus/moduli

theta-argument represent angle theta

[tex]= r_1r_2(cos \theta_1 + i sin \theta_1) (cos \theta_2 + isin \theta_2)[/tex]

[tex]= r_1r_2(cos \theta_1 cos \theta_2 + i cos \theta_1 sin \theta_2 + i sin \theta_1 cos \theta_2 + i^2sin\theta_1sin\theta_2[/tex]

The value of i square is

[tex]i^2=-1[/tex]

Therefore,we get,

[tex]= r_1r_2(cos \theta_1 cos \theta_2 + i cos \theta_1 sin \theta_2 + i sin \theta_1 cos \theta_2 + (-1)sin \theta_1 sin \theta_2)[/tex]

[tex]= r_1r_2(cos \theta_1 cos \theta_2 + i cos \theta_1 sin \theta_2 + i sin \theta_1 cos \theta_2 - sin \theta_1 sin \theta_2)[/tex]

Since we know that,

[tex]cos(\theta_1+\theta_2)=cos\theta_1cos\theta_2-sin\theta_1sin\theta_2[/tex]

[tex]sin(\theta_1+\theta_2)=sin\theta_1cos\theta_2+cos\theta_1sin\theta_2[/tex]

So using above value we get,

[tex]= r_1r_2(cos \theta_1 cos \theta_2 - sin \theta_1 sin \theta_2) + i (cos \theta_1 sin \theta_2 + sin \theta_1 cos \theta_2)[/tex]

[tex]=r_1r_2cos(\theta_1+\theta_2)+isin(\theta_1+\theta_2)[/tex]

Therfore the product of the complex number is z1z2 = r1r2[cos (θ1+θ2) + isin (θ1+θ2)].

Answer:

886.13sq. units

Step-by-step explanation:

If the figure is a triangle

Area of the triangle =  1/2 ab sintheta

Given

a = 41 units

b = 23 units

theta = 70°

Area of the triangle  = 1/2 * 41 * 23 sin 70

Area of the triangle = 943 sin70

Area of the triangle = 943(0.9397)

Area of the triangle = 886.13

Hence the area of the triangle is 886.13sq. units

Answer: t-test for a difference in means

Step-by-step explanation:

edg 2021

The name of the appropriate inference procedure is a t-test for a difference in means.

A t-test can be defined as a type of inferential statistic which is typically used to compare and show a significant difference between the means of two (2) groups that are drawn from a normally distributed data set (population).

This ultimately implies that, the name of the appropriate inference procedure to conduct a hypothesis test in this scenario is a t-test for a difference in means.
