Answer:
BC=48cm
Step-by-step explanation:
Let A= reference angle,
AC=h=60cm
AB=b=36cm
BC=p=?
Using pythogorean theorem,
h^2=p^2+b^2
√(60^2-36^2)=p
√2304=p
p=48cm

Answer:
5.33 cm
Step-by-step explanation:
The smallest positive zero of the polynomial with d=0.55 is about 5.33. We presume the units are cm.
The ball sinks to a depth of 5.33 cm.

I find a graphing calculator shows the zeros of higher-degree polynomials easily. The function graph is attached.
For the purpose here, the vertical scale factor π/3 can be eliminated, as it does not change the values of the zeros. That is, the polynomial we need to solve is x²(x -15) +275 = 0.
It turns out that a reasonable iterator for finding a solution is x' = √(275/(15 -x)). x = 5 is a reasonable starting point. The iterator is what you get by solving for the x outside the parentheses in the above cubic equation.
Find the equation of the line. A line that is perpendicular to the graph of 3x +2y =6 and contains the point (6,-3)
9514 1404 393
Answer:
2x -3y = 21
Step-by-step explanation:
The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.
3x +2y = 6 . . . . . given equation
2x -3y = c . . . . . . coefficients swapped, one negated
2(6) -3(-3) = c = 21 . . . . . the value of c for the given point
The desired equation is ...
2x -3y = 21

Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centimetres. Write down, in imillimetres, the lower bound of his measurement.
The lower bound of the measurement is 65.5 millimetres.
A centimetre equals 10 millimetres, a measure is expressed by the measured magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:
[tex]y = x + \epsilon[/tex] (1)
Where:
[tex]x[/tex] - Measured magnitude, in millimeters.[tex]y[/tex] - Possible magnitude, in millimeters.[tex]\epsilon[/tex] - Uncertainty, in millimeters.If we know that [tex]y = 67.5\,mm[/tex] and [tex]\epsilon = 1\,mm[/tex], then the lower bound of the measurement is:
[tex]y = 67.5\,mm - 2\cdot (1\,mm)[/tex]
[tex]y = 65.5\,mm[/tex]
The lower bound of the measurement is 65.5 millimeters.

what value of t makes the following equation true?
Answer:
t = 108
Step-by-step explanation:
[tex]\frac{5}{9}[/tex] t - 27 = [tex]\frac{1}{9}[/tex] t + 21 ( subtract [tex]\frac{1}{9}[/tex] t from both sides )
[tex]\frac{4}{9}[/tex] t - 27 = 21 ( add 27 to both sides )
[tex]\frac{4}{9}[/tex] t = 48 ( multiply both sides by 9 )
4t = 432 ( divide both sides by 4 )
t = 108

A triangle is shown on the graph:
A coordinate plane is shown. A triangle has vertices at negative 6 comma 2, negative 5 comma 5, negative 2 comma 2.
What effect will a 90-degree clockwise rotation have on the triangle? Be sure to address how it could impact the angles, side lengths, and any congruency between the original pre-image and the image.
9514 1404 393
Answer:
the image is congruent with the original, angles and lengths are unchanged
Step-by-step explanation:
Translation, rotation, and reflection are known as "rigid transformations". Effectively, you can cut the figure from some rigid material, and move it according to any of these transformations without causing it to deform in any way.
All lengths and angles retain their measures when the figure is rotated about any point, through any angle. The rotated figure is congruent with the original.

Here, the triangle is defined in the second quadrant. Rotating it 90° clockwise will move it to the first quadrant. The transformation of coordinates is ...

compare the expressions
3 X 10 and 15 x 20 without multiplying them. Explain how she
could compare the factors to compare the expressions without
multiplying them.
Answer:
yes
Step-by-step explanation:
Well 3 is a factor of 15, and 10 a factor of 20. So 15/3 is 5, and 20/10 is 2.
5*2 is 10, which means that 15*20 is 10 times greater than 3*10.
If you actually did multiply them, 15 by 20 is 300 and 3 by 10 is 30. It would logically be correct.

Algebra 2 help needed....
Answer:
Step-by-step explanation:
We actually don't need to know all of the restrictions.
We know that a vertical stretch factor of 4 means multiplying a square root function by [tex]4[/tex]. So, the answer will be in the form [tex]y=4\sqrt{x+c}+k[/tex], where c and k are real numbers.
Aha! Only one of these conditions satisfy the restrictions, so we have that [tex]\boxed{y=4\sqrt{x+3}+7}[/tex] has to be the answer.
Lynette wanted to run one mile in eight minutes. To be on pace to reach
her goal, how far will she need to run in 2 minutes? ?

find the speed she intends to run with, ie total distance/time
[tex]\frac{1}{8} miles \: per \: minute[/tex]
find the distance she travels in two minutes, ie speed multiplied by time.

Answer:
(y-3)²= -32x
Step-by-step explanation:
1) the required equation has a form: (y-y₀)²=-2p(x-x₀), where (x₀;y₀) - vertex (0;3), p - parameter of the given parabola;
x₀=0; y₀=3.
2) according to the conditiion F(-8;3)=F(x₀+p/2; y₀), it means (x₀+p/2; y₀)=(p/2;3), then p/2= -8; ⇒ p= -16.
3) finally, p= -16; x₀=0; y₀=3, then it is possible to make up the required equation:
(y-3)²= -32x.

Plot all points that are a distance of 7 units from 4. What are their values?
Distance is the number of units between points.
The distance that are 7 units from 4 are: 11 and -3
A distance of 7 units from 4 means:
[tex]x - 7 = 4[/tex] or [tex]x + 7 =4[/tex]
Where:
x is the required distance
Solve for x in both equations.
[tex]x - 7 = 4[/tex]
[tex]x = 7 + 4[/tex]
[tex]x = 11[/tex]
[tex]x + 7 =4[/tex]
[tex]x =4 - 7[/tex]
[tex]x =- 3[/tex]
So, the distance that are 7 units from 4 are: 11 and -3
