Write the equation of the circle in standard form with the center (4,-2) and radius 5.
Answers
(x-h)^2+(y-k)^2=r^2
h: 4
k:-2

tan^2A -sin^2A=sin^2a Tan^2A
Answers
Answer:
see explanation
Step-by-step explanation:
Using the identity
sin²A = 1 - cos²A , tanA = [tex]\frac{sinA}{cosA}[/tex]
Consider the left side
tan²A - sin²A
= [tex]\frac{sin^2A}{cos^2A}[/tex] - sin²A
[tex]\frac{sin^2A-sin^2Acos^2A}{cos^2A}[/tex]
= [tex]\frac{sin^2A(1-cos^2A)}{cos^2A}[/tex]
= [tex]\frac{sin^2A.sin^2A}{cos^2A}[/tex]
= sin²A × [tex]\frac{sin^2A}{cos^2A}[/tex]
= sin²A . tan²A
= right side , thus verified
Cody must walk 5/8 of a mile to get to school. If he walks to and from school each school day, how many miles would he walk in 2 weeks to and from school?
Answers
Answer:
17 1/2 miles
Step-by-step explanation:
there are 14 days in 2 weeks
2 x 7 = 14
total miles walked to and from school = 5/8 x 2 = 10/8
total miles walked = 10/8 x 14 = 17 1/2 miles

Mindy is the head cheerleader on her suad. She is making banners to place throughout the school for the first football game of the season. She used ⅔ cup of glitter to make 1 cup of glittery paint. Using this same proportion, how many cups of glitter will Mindy use to make 9 cups of glittery paint?
Answers
Answer:
[tex]6\:\text{cups}[/tex]
Step-by-step explanation:
Since the proportion is maintained, we can set up the following proportion:
[tex]\frac{2/3}{1}=\frac{x}{9}[/tex], where [tex]x[/tex] is the amount of glitter, in cups, Mindy will use to make 9 cups of glittery paint.
Cross-multiply to get:
[tex]1x=9\cdot \frac{2}{3},\\x=9\cdot \frac{2}{3}=\boxed{6\:\text{cups}}[/tex]
Consider right triangle MNO below which expression represents the length of side MN
Answers
We can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.
What do you mean by Right Angle Triangle?A right angle triangle is a triangle in which one of the angles is equal to 90 degrees. In other words, it is a triangle in which one angle is a "right angle." Right angle triangles are commonly used in geometry and trigonometry, and they play a crucial role in many real-world applications, such as surveying, construction, and navigation.
In a right triangle, the length of one side can be found using the sine function. The sine of an angle in a right triangle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. In this case, the angle MNO is 25 degrees, so we can write the following equation to find the length of side MN:
MN = NO * sin(25°) = 4 cm * sin(25°)
To find the numerical value of MN, we can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.

Answer:
a = 7, b = [tex]\frac{7\sqrt{3} }{3}[/tex]
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{a}{7\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
a × [tex]\sqrt{2}[/tex] = 7[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{b}[/tex] = [tex]\frac{7}{b}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by b )
b × [tex]\sqrt{3}[/tex] = 7 ( divide both sides by [tex]\sqrt{3}[/tex] )
b = [tex]\frac{7}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex] = [tex]\frac{7\sqrt{3} }{3}[/tex]

1-Jace receives a shipment of 700 oranges.He randomly selects 25 oranges to weigh.In that sample, 2 oranges weigh 5 ounces.How many oranges in the shipment canJace predict weigh 5 ounces? *
Answers
Answer: 56 oranges
Step-by-step explanation:
In a sample of 25 oranges, 2 oranges weigh 5 ounces.
Proportionally represented, that would be:
= 2 / 25
Assuming the 25 is representative for all 700 oranges, the number of oranges that can be expected to weigh 5 ounces from the shipment is:
= Proportion of 5 ounces oranges from sample * Total number of oranges
= 2/25 * 700
= 56 oranges
