D. a translation right 10 and up 9
Step-by-step explanation:
In order to find the translation, you can take two corresponding points and find the difference in their x's and y's. For example, I'll use N and N':
Step 1) N (-3, -5) and N' (7, 4)
Step 2) difference in y: 4 - (-5) = 9; difference in x: 7 - (-3) = 10
Step 3) a translation right 10 units and up 9 units
1) identify what coordinates points N an N' are
2) find the difference in the points
3) identify whether he shape moved up or down, and left or right. You can see it moved up and right, so you you can tell it moved up 9 since that's the difference in y's and right 10 since that's the difference in x's

Find the diameter and radius of a circle to the nearest hundredth with the given circumference.
C = 40 in
Answers
Answer:
Radius = 6.40
Diamater - 12.70
Step-by-step explanation:
hope this helped!
The diameter and radius of a circle to the nearest hundredth with the given circumference, C = 40 inches is 12.73 inches and 6.37 inches.
What is Circumference of a Circle?Circumference of a circle is defined as the total length of the boundary of the circle.
The concept is same as the perimeter for straight sided figures.
The formula to calculate the circumference of the circle is given by,
Circumference = 2πr
Here r is the radius of the circle.
Given C = 40 inches
2πr = 40
πr = 40 / 2
πr = 20
r = 20/π = 6.366 ≈ 6.37
Diameter = 2 × radius = 2r = 12.732 ≈ 12.73
Hence the diameter and radius are 12.73 inches and 6.37 inches.

Consider the quadrilateral shown below that has vertices A, B, C, and D.
Suppose we know the following measurements:
¯¯¯¯¯¯¯¯AB=5.8 cm
¯¯¯¯¯¯¯¯BC=5.4 cm
¯¯¯¯¯¯¯¯¯CD=3.3 cm
¯¯¯¯¯¯¯¯¯AD=6.2 cm
m∠A=27∘
What is the degree measure of ∠C?
m∠C= °
Answers
Answer:
C = 25.94°
Step-by-step explanation:
By applying cosine rule in ΔABD,
BD² = AB² + AD² - 2(AB)(BD)cosA
BD² = (5.8)² + (6.2)² - 2(5.8)(6.2)(cos27°)
BD² = 33.64 + 38.44 - 64.08
BD² = 8
BD = √8
By applying cosine rule in ΔBCD,
BD² = BC² + CD²- 2(BC)(CD)cosC
(√8)² = (5.4)²+ (3.3)² - 2(5.4)(3.3)cosC
8 = 29.16 + 10.89 - 35.64cosC
35.64cosC = 32.05
cosC = 0.89927
C = [tex]\text{cos}^{-1}(0.89927)[/tex]
C = 25.94°
By using cosine formula of triangles we got that measure of ∠C is 25.94 °
What is a quadrilateral ?Quadrilateral is a closed shape with 4 sides and 4 corners.

in [tex]\triangle \mathrm{ABD}[/tex]
Applying cosine formula
[tex]$$\begin{aligned}&\mathrm{BD}^{2}=\mathrm{AB}^{2}+A D^{2}-2(\mathrm{AB})(\mathrm{BD}) \cos A \\\\&\mathrm{BD}^{2}=(5.8)^{2}+(6.2)^{2}-2(5.8)(6.2)\left(\cos 27^{\circ}\right) \\\\&\mathrm{BD}^{2}=33.64+38.44-64.08\\ \\&\mathrm{BD}^{2}=8 \\\\&\mathrm{BD}=\sqrt{8}\end{aligned}$$[/tex]
Now in [tex]\triangle B C D[/tex]
Applying cosine formula
