Answer:
± 5
Step-by-step explanation:
[tex]\sqrt{25}[/tex] = ± 5 , that is
+ 5 or - 5 , since
+ 5 × + 5 = 25 and - 5 × - 5 = 25
A sculptor is planning to make two triangular prisms out of steel. The sculptor will use △ABC for the bases of one prism and △DEF for the bases of the other prism.
(a)Is △ABC similar to △DEF? Explain.
(b)Suppose the sculptor makes both prisms with the same height. Which prism will have a greater volume? How many times greater? SHOW YOUR WORK FOR BRAINLIEST!!
Answer:
a)
Verify is the corresponding sides have same ratio:
AB / DE = 50/60 = 5/6 BC / EF = 20/24 = 5/6Since the ratios are same, the triangles are similar
b)
If one dimension is same, the base areas will make difference by the square of the scale factor:

Determine the Equation of the line Perpendicular to 2x -3y +5= 0 and passers through (-6,-3)
9514 1404 393
Answer:
3x +2y +24 = 0
Step-by-step explanation:
In general, the equation of a perpendicular line can be found by swapping the coefficients of x and y, then negating one of them. The value of the constant will be what is required to make the line pass through the given point.
The equation will be of the form ...
3x +2y +c = 0
At the given point, (x, y) = (-6, -3), we have ...
3(-6) +2(-3) +c = 0 . . . . substitute the given point coordinates
-18 -6 +c = 0 . . .simplify
c = 24 . . . . . . . . add 24
The general-form equation for the line is ...
3x +2y +24 = 0 . . . . . shown in blue in the attachment
given the f(x)=x+2 g(x)=3x²-1 what is (fg) (x)?
Answer:
(f·g)(x) = 3x² + 1Step-by-step explanation:
Given:
f(x)=x+2, g(x)=3x²-1To find:
(f·g) (x) = ?Solution:
(f·g)(x) = f(g(x)) = f(3x²-1) = (3x²-1) + 2 = 3x² + 1(f·g)(x) = 3x² + 1A biologist is studying the growth rate of a bacteria sample. The sample started with a bacterial count of 331.

slope of (-2,6) (-5,-4)
Answer:
10/3
Step-by-step explanation:
(-2, 6) & (-5, -4)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - 6) / (-5 - (-2))
Simplify the parentheses.
= (-4 - 6) / (-5 + 2)
= - 10 / -3
Simplify the fraction.
-10/-3
= 10/3
This is your slope.

Find the volume
A. 150 cm3
B. 180 cm3
C. 90 cm3
D. 90 cm2
Answer:
268 in²
Step-by-step explanation:
The surface area is basically the entire area of the figure. You can do it multiple ways, but this is how I did it. I found the area of each side and added them all together. There are three sets of identical sides. First, we'll calculate the area of the side with lengths 10" and 8".
10 · 8 = 80
There are two of these sides, so currently we have 80 + 80.
Next, the area of the sides with lengths 8" and 3". These are the sides at the top and bottom.
8 · 3 = 24
So to our equation we now have 80 + 80 + 24 +24.
For the final two sides, we have the dimensions 10" and 3".
10 · 3 = 30
To our equation, we add this to get 80 + 80 + 24 + 24 + 30 +30.
Add all these numbers together for 268.
In the correct form, we add the square symbol to show that we are talking about area. The answer is 268 in². Good luck :D
If an item is discounted by 5 percent, and the final price is 57, what is the original price of the item?
Answer:
$59. 85 or rounding, $60 (I AM NOT COMPLETELY SURE)
Step-by-step explanation
I changed the percentage into a decimal (.05) and then multiplied it by the final price (57). After multiplying, I got, $2.85. I then added that to the final price to get, $59.85.

find value of X in cos(3x-30°)=sin(7x+50°)
Answer:
7
Step-by-step explanation:
Given the expression
cos(3x-30°)=sin(7x+50°)
In trigonometry cosx = sin(90-x)
Hence
Cos(3x-30) = sin(90-(3x-30))
Cos (3x-30) = sin(90-3x+30)
Cos (3x-30) = sin(120-3x)
Substitute into the expression above
Sin(120-3x) = sin(7x+50)
120-3x = 7x+50
Collect like terms
-3x-7x = 50-120
-10x = -70.
x = 70/10
x = 7
Hence the value of x is 7

Find the volume to the nearest millimeter of a cylinder that is 45 millimeters tall and has a diameter of 26 millimeters. Use 3.14 for pie.
Answer:
Volume = π • r² • height
Volume = 3.14 • 13² • 45
Volume = 23,879.7 cubic millimeters
Volume = 23,880 cubic millimeters (to nearest millimeter)

If mZACD = 100°, then mZACE = [?]°
Answer:
80 degrees
Step-by-step explanation:
a line is always 180 degrees
one side of that line is 100
so, just subtract 100 from 180
you get 80
180 - 100 = 80
