Mary is making a pinata that has a ball-like shape. The pinata has a surface area of
60 square feet. Use the formula for the surface area of a sphere:
S=471?
to find the radius of the pinata in feet.
Answer:
2.19 ft
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
Surface area of the sphere = 60 ft²
The formula to find the radius of a sphere
= √A/4π
= √60/4 × π
= 2.19 ft
Therefore, the radius of the pinata = 2.19 ft

Answer:
(2, -3), (3, -3)
Step-by-step explanation:
y = x^2 - 5x + 3
y = -3
x^2 - 5x + 3 = -3
x^2 - 5x + 6 = 0
(x - 3)(x - 2) = 0
x - 3 = 0 or x - 2 = 0
x = 3 or x = 2
We are given y = -3.
Answer: (2, -3), (3, -3)
Answer:
(2, -3) , (3, -3)
Step-by-step explanation:
One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,
[tex]f(x)=x^2-5x+3[/tex]
Set this equation up, and solve to find the value of (x) that satisfies this requirement:
[tex]f(x)=x^2-5x+3=-3[/tex]
Inverse operations,
[tex]x^2-5x+6=0[/tex]
Factor, rewrite the quadratic equation as the product of two linear equations,
[tex](x-2)(x-3)=0[/tex]
Therefore the solutions are the following, the (x-coordinate) represents the input, and the (y-coordinate) represents the output.

What is the y-intercept for y = 3x2 + 2x - 5 ?
Answer:
y-intercept- (0,-5)
x-intercept ( 1 , 0 ) , ( − [tex]\frac{5}{3}[/tex] ,0)
Step-by-step explanation:
y-intercept- (0,-5)
x-intercept ( 1 , 0 ) , ( − [tex]\frac{5}{3}[/tex] ,0)
Answer:
If by 3x2 you meant 3(2), then the y-intercept is 1.
Step-by-step explanation:
We need to start by simplifying the equation.
y = 3(2) + 2x - 5
y = 6 + 2x - 5
y = 2x + 6 - 5
y = 2x + 1
The "2x" part tells us the growth rate, or slope, of the line, and the "+ 1" is the y-intercept.

Step 2: Check
Verify ΔLMN is a right triangle
Substitute in variables [Pythagorean Theorem]: 24² + 10² = 34²Evaluate exponents: 576 + 100 = 1156Add: 676 ≠ 1156∴ ΔLMN is not a right triangle
giving brainliest and if u cant read down it says: if the spinner is spun 540 times throughout the day, how many dog or cat toys are expected to be given away? please help.
Answer:
324/540 cats and dogs should be expected to be given away
Step-by-step explanation:
First, write the fraction of the cats on the spinner plus the dogs on the spinner.
[tex]\frac{4}{10} + \frac{2}{10} = \frac{6}{10}[/tex]
Now, we have to make the denominator 540 but we have to make it equal so you divide.
540 ÷ 10 = 54
So, our fraction should look like this.
[tex]\frac{x}{540}[/tex]
Now, multiply 6 × 54 = 324
[tex]\frac{324}{540}[/tex] is our answer
Have a great day!
The dog or cat toys are expected to be given away = 378
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
If the spinner is spun 540 times throughout the day.
Total fraction of the cat and dogs together,
= 5/10+2/10
=7/10
Divide the 540 into 10 equal parts,
= 540/10
=54
let 'x' dog or cat toys are expected to be given away
So, x/540 = 7/10
x= 54*7
x= 378.
Hence, dog or cat toys are expected to be given away = 378/540

Answer:
a=12
Step-by-step explanation:
We must use SOH, CAH, TOA
SOH= Sin0=opp/hyp
CAH=Cos0=adj/hyp
TOA= Tan0=opp/adj
Since we have opposite and hypotenuse we use Sin ratio, in this case,
sin30°= [tex]\frac{a}{24}[/tex]
[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply
[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself
a=12
Answer:
a = 12
Step-by-step explanation:
To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;
Sin(30) = [tex]\frac{a}{24}[/tex]
Sin(30) * 24 = a
12 = a
