Answer:
r = [tex]2\sqrt{5}[/tex]
[tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Is this a live test question or a homework question?
Step-by-step explanation:
the radius is the distance between (3, 2) and (5, -2)
[tex]r^{2}[/tex] = [tex]{(3 - 5)^{2} + (2 + 2)^{2} }[/tex]
= [tex](-2)^{2} + 4^{2}[/tex]
= 4 + 16 = 20
r = [tex]\sqrt{20 } = 2\sqrt{5}[/tex]
Equation of circle: [tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Answer:
Radius: [tex]2\sqrt{5}[/tex]
Equation of circle: [tex](x-3)^2+(y-2)^2=20[/tex]
Step-by-step explanation:
The radius of a circle is equal to the distance between the center of the circle and any point on the circle. Therefore, we have:
[tex]r=\sqrt{(5-3)^2+(2-(-2))^2},\\r=\sqrt{2^2+4^2},\\r=\sqrt{20}=\boxed{2\sqrt{5}}[/tex]
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex].
What we know:
radius of [tex]2\sqrt{5}[/tex] center at [tex](3, 2)[/tex]Substituting known values, we get:
[tex](x-3)^2+(y-3)^2=(2\sqrt{5})^2,\\\boxed{(x-3)^2+(y-2)^2=20}[/tex]

Honon spent 3 1/4 hours on homework while Sequoia spent 2 5/6 hours on homework. How much more time did Honon spend on homework than Sequoia
Answer:
5/12 hours
Step-by-step explanation:
Honon = 3 1/4 hours
Sequoia = 2 5/6 hours
How much more time did Honon spend on homework than Sequoia
= number of hours Honon spent - number of hours Sequoia spent
= 3 1/4 hours - 2 5/6 hours
= 13/4 - 17/6
= (39-34) /12
= 5/12 hours

Step-by-step explanation:
Three game tickets and four ride tickets cost $39. Five ride tickets cost $15. All game tickets cost the same and all ride tickets cost the same. What is the ratio of the cost of a game ticket to the cost of a ride ticket?
Answer: 3:1
Step-by-step explanation:
Let the cost of a game ticket be g.
Let the cost of a ride ticket be r.
The information given can be formed into an equation which will be:
3g + 4r = 39
Since Five ride tickets cost $15, the cost of each ride ticket will be:
= $15/5
= $3.
Therefore, 3g + 4r = 39
We put the value of r = $3 into the equation
3g + 4(3) = 39
3g + 12 = 39
3g = 39 - 12
3g = 27
g = 27/3
g = 9
The cost of a game ticket is $9
The ratio of the cost of a game ticket to the cost of a ride ticket will be:
= 9/3
= 3/1
= 3:1
The ratio is 3:1
Simplify.
(-x²+2x-3)+(7x²+6x+5)
Answer:
6x² + 8x + 2
Step-by-step explanation:
(-x² + 2x - 3) + (7x² + 6x + 5 ) = ?
-x² + 2x - 3 + 7x² + 6x + 5 = ?
-x² + 7x² + 2x + 6x - 3 + 5 = ?
? = 6x² + 8x +2

PLEASEEE HELPPP its due in 10 mins PLSSS
Answer:
About 525 times.
Step-by-step explanation:
You have a 5 in 8 chance of getting a consonant originally. You should try to find an equal ratio except with 840 as the second number. As of now it's 5/8 = ?/840
8 is a factor of 840 and if you divide 840 by 8 you get 105. If you actually think about it 105/840 would be an equal ratio to 1/8 so you multiply 108 by 5 to get 525.

Jackson recorded the growth of a plant over 10 weeks. The equation y=0.25x+4 represents the height in inches over the time in weeks. How tall will the plant be after 5 weeks? How tall will it be after 12 weeks? (PLEASE HELP)
Answer:
5.25 inches after 5 wks
7 inches after 12 wks
Step-by-step explanation:
after 5 weeks: y = .25(5) + 4 which is 5.25 inches
after 12 weeks: y = .25(12) + 4 which is 7 inches

find the area of ABCD
trapezoid ABCD ~ trapezoid EFGH
trapezoid ABCD: 20cm
trapezoid EFGH: 5cm
area of EFGH = 40 sq cm
Answer:
640 cm²
Step-by-step explanation:
The ratio of the area of 2 similar polygons = the ratio of the square of their corresponding lengths
Thus:
Area of Trapezoid ABCD to Area of Trapezoid EFGH = AB² to EF²
Area of Trapezoid ABCD = ? = x
Area of Trapezoid EFGH = 40 cm²
AB = 20 cm
EF = 5 cm
Substitute
x:40 = 20²:5²
x/40 = 400/25
x/40 = 16
Cross multiply
x = 16*40
x = 640
Area of trapezoid ABCD = 640 cm²

angle t = ___?
Answer:
[tex]141^{\circ}[/tex]
Step-by-step explanation:
The quadrilateral in the image is a cyclic quadrilateral, because it is circumscribed by a circle. In all cyclic quadrilaterals, each pair of opposite sides are supplementary (add up to 180 degrees). Therefore, we have the following equation:
[tex]m\angle T+39=180,\\m\angle T=\boxed{141^{\circ}}[/tex]

This beach ball has a surface area of 379.94 inches². What is its diameter? Use 3.14 for π.
Answer:
11 inches
Step-by-step explanation:
We know that [tex]SA=4\pi r^2[/tex]. We know that [tex]SA=379.94[/tex] and that [tex]\pi\approx3.14[/tex]. We solve for [tex]r[/tex]: [tex]379.97=4\times3.14\times r^2[/tex]
[tex]r^2=30.25[/tex]
[tex]r=5.5[/tex]
Since [tex]d=2r[/tex], the diameter of the sphere is 11 inches.

7^9/7^2
Answer:
1) b⁵⁴
2) 7⁷
Step-by-step explanation:
When you have an exponent raised to an exponent, like in #1, you simply multiply the exponents.
When you are dividing two numbers with exponents and they have the same base, like in #2, you subtract the denominator exponent from the numerator exponent.

The perimeter of a right -angled triangle is 72 cm . Its side are in the ratio 3 : 4: 5.Work out the longest length of the triangle.
Answer:
The longest length is 30 cm
Step-by-step explanation:
Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides
So, what we have to do here is divide the perimeter in the given ratio to get the side lengths
since 5 is the biggest of the numbers in the ratio, it represents the largest length value
so we have this as;
(3 + 4 + 5) = 12
So that would be;
5/12 * 72
= 5 * 6 = 30

Step-by-step explanation:
these angles will add to 90 deg
90 = 22 + 2x
solve for x
Answer:
x = 34°
2x = 68°
Step-by-step explanation:
Both angles are complementary (add up to the sum of 90°), so we can say;
22 + 2x = 90°
2x = 90 - 22
2x = 68
x = 68 / 2
x = 34°
Furthermore:
If you have to find the value of 2x it would be 68, since
2x = 2(34) = 68°
Hope this helps!
