Step-by-step explanation:Hi there !
Cylinder volume formula
V = π·r²·h
π ≈ 3.14
replace
V = 3.14×(19cm)²×12cm
= 3.14×361cm²×12cm
= 13602. 48 cm³

Match each equation with its number of unique solutions.
y = 3x^2- 6x + 3
y= -x^2 - 4x + 7
y = -2x^2 + 9x – 11
Answers
Answer:
1. 1 real solution
2. 2 real solutions
3. Two complex solutions
Step-by-step explanation:
y = 3x^2- 6x + 3
This has 1 real solutions.
y= -x^2 - 4x + 7
This has 2 real solutions.
y = -2x^2 + 9x – 11
This has 2 complex solutions.
The number of unique solutions each equation has is required.
[tex]y=3x^2-6x+3[/tex] has one real solution.
[tex]y=-x^2-4x+7[/tex] has two real solutions.
[tex]y=-2x^2+9x-11[/tex] has two complex solutions.
The number of solutions is determined by the value of the discriminant.
Let us find the determinant of each equation
[tex]y=3x^2-6x+3[/tex]
[tex]D=b^2-4ac\\\Rightarrow D=6^2-4\times 3\times 3\\\Rightarrow D=36-36\\\Rightarrow D=0[/tex]
The equation has one real solution.
[tex]y=-x^2-4x+7[/tex]
[tex]D=(-4)^2-4\times (-1)\times 7\\\Rightarrow D=16+28\\\Rightarrow D=44\\\Rightarrow D>0[/tex]
The equation has two real solutions.
[tex]y=-2x^2+9x-11[/tex]
[tex]D=9^2-4\times (-2)\times (-11)\\\Rightarrow D=81-88=-7\\\Rightarrow D<0[/tex]
The equation has two complex solutions.

Answers
Answer:
x-int: (-1.2, 0)
y-int: (0, -0.7)
Step-by-step explanation:
The x-intercept is the x value when y = 0.
Another way to reword that is when the graph crosses the x-axis.
The y-intercept is the y value when x = 0.
Another way to reword that is when the graph crosses the y-axis.
According to the graph, when y = 0 and when the line crosses the x-axis, the x-value is -1.2. Therefore, our x-intercept is (-1.2, 0).
According to the graph, when x = 0 and when the line crosses the y-axis, the y-value is -0.7. Therefore, our x-intercept is (0, -0.7).

Aiko jumped rope for an amazing 20 minutes. She stopped at 8:05. When did she start jumping?
Answers
Answer:
7:45 is when Aiko started jumping rope.
Step-by-step explanation:
If you start with 8:05 then subtract the 5 minutes you only have 15 minutes to calculate. Then you do 60 - 15 because there are 60 minutes in one hour. If you do that you are left with 45 and the hour would be 7 so the answer is 7:45

Answers
Answer:
The Answer is $3180..Step-by-step explanation:
principal (p) = $ 530Interest Rate (R) = 6%Time (T) = 1 yearSimple Interest (I) = ?By using formula,
Simple Interest (I)= P× T× R/ 100
= $530 × 1 year× 6%
= 530 × 1 × 6
= $3180
Therefore , The simple Interest is $3180.
If you like this answer then mark this answer as BRAINLIEST answer.....Thank you ☺️☺️
The simple interest will be equal to $3180.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
Given that:-
principal (p) = $ 530
Interest Rate (R) = 6%
Time (T) = 1 year
Simple Interest (I) = ?
The formula to calculate the simple interest is given below:-
Simple Interest (I)= P× T× R/ 100
SI = $530 × 1 year× 6%
SI = 530 × 1 × 6
SI = $3180
Therefore, the simple interest will be equal to $3180.

The cost of an Uber ride can be modled by y = 3x + 5, where x is the number of miles driven. You paid $44 in a
cab fare, how many miles did you drive?
Answers
Answer:
13
Step-by-step explanation:
44=3x+5
44-5=39
39/3=13
Answer:
13 miles driven
Step-by-step explanation:
y = 3x + 5
Y is the amount we paid, so we insert 44 into the equation.
44 = 3x + 5
Any thing you do to one side of the equation, you do to the other side, so -5 from both sides.
44-5 = 39
5-5 = 0
So you are left with:
39 = 3x + 0 (So you can ignore the 0)
Like I said earlier, anything you do to one side of the equation you do to the other so divide both sides by 3:
39 divided by 3 = 13
3 divided by 3 = 1
So now you have:
13 = 1x
So x = 13 and that is how many miles you drove.

Two angles in a triangle are equal and their sum is equal to the third angle in the triangle. What are the measures of each of the three interior angles?
Answers
Answer:
45º, 45º, 90º
Step-by-step explanation:
Assume angles are x then third is x+x = 2x.
sum of angles in a triangle = 180
=> x + x + 2x = 180
=> 4x = 180
=> x = 180/4 = 45
so, angles are 45,45 and 90.
