Answer:
FALSE
Step-by-step explanation:
<E in ∆AED ≅ <E in ∆CEB.
Both are 90°.
Side ED ≅ Side EB
Side AD ≅ Side CB.
Thus, two sides (ED and AD) and a non-included angle (<E) of ∆AED are congruent to corresponding two sides (EB and CB) and a non-included angle (<E) of ∆CEB. Therefore, by A-S-S Congruence Theorem, both triangles are congruent to each other not by SSS.

Trying to factor by splitting the middle term
3.1 Factoring 9v2-9v-1
The first term is, 9v2 its coefficient is 9 .
The middle term is, -9v its coefficient is -9 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 9 • -1 = -9
Step-2 : Find two factors of -9 whose sum equals the coefficient of the middle term, which is -9 .
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
A new treatment for depression involves a one month stay on a Caribbean island and daily therapy sessions with a team of 8 professionals. A researcher knows that people with untreated depression miss an average of μ = 4.30 days of work per month (σ = 1.1). It was found that a random sample of 121 depressed individuals who underwent the new treatment missed an average of M = 4.08 days of work per month following treatment. Thus, the research question is: what is the impact of this treatment on absenteeism (i.e., days missed from work)?

Find an equation of the line that passes through (6,-1) and has a slope of 3
Answers
Answer:
The equation is: y y = 5/4 * x - 13
Step-by-step explanation:
The slope-intercept y = mx + c form of a straight line is In this case we have a point, (x, y) and the slope, m so all we need is a value for c. Substitute into y = mx + c - 3 = 5/4 * (8) + c - 3 = 10 + c c = - 13 y = 5/4 * x - 13 The equation is: y the formula for the situation have a point, (x 1 ,y 1 ) and the slope, Or you can use where you (m) y-y 1 =m(x-x 1 ) y - (- 3) = 5/4 * (x - 8) y + 3 = 5/4 * x - 10 y = 5/4 * x - 13 Answer link < II

A person is looking from a car to the top of a building. The angle of elevation to the top of the building from the car is 32°. The building is 200 feet away. How tall is the building? Round to the nearest foot.
Answers
Answer:
132.2 ft
Step-by-step explanation:
This is a right angle problem where 32 is the angle and 200 feet is the leg unederneath. To solve for the height we use tangent since we have the adjacent side and we are solving for the opposite side.
Steps:
1. tan32 = x/200
2. (tan32)200=x

What is the length of a diagonal of a square with a side length of 8?
A. 4
B. 42
C. 43
D. 82
Answers
Answer:
D. 8[tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the diagonal of the square, you can use the Pythagorean theorem* to find the hypotenuse since the diagonal cuts the square into two right triangles with legs of 8 units in length:
If in a^2 + b^2 = c^2, a = 8 and b = 8,
8^2 + 8^2 = c^2 (put 8 as both the leg lengths in the equation)
128 = c^2 (calculate 8^2 and then add the two terms together)
c = 8[tex]\sqrt{2}[/tex] (square both sides)
So, the length of the diagonal is 8[tex]\sqrt{2}[/tex] units
*the Pythagorean theorem is a theorem used to find the sides lengths of a right triangle: a^2 + b^2 = c^2. a and b are the legs of the triangle, and c is the hypotenuse.

A house has increased in value by 35% since it was purchased. If the current value is $297,000, what was the value when it was purchased?
Answers
Answer:
Answer:
$260,000
Step-by-step explanation:
Explanation:
Given the problem above, we solve for original value
Hence, in this case, we are given
percentage (35%) and the New Value ($351,000).
We can substitute this into the formula and solve for X
Let X be the original price, Hence, X = 100%
Therefore, $351000 = 135%
Divide both sides by 135
351000÷ 135 = 135÷135
2600 = 1%
Multiply both sides by 100
2600 * 100 = 1% * 100
$260000 = 100% = X
Hence, final answer is $260000
Solve: (x −6)−(4.5−x )= −1.5
PLZ HELP
Answers
Answer:
x=9/2 Hope this helps!
Step-by-step explanation:
Let's solve your equation step-by-step.
x−6−(4.5−x)=−1.5
Step 1: Simplify both sides of the equation.
x−6−(4.5−x)=−1.5
x−6+−1(4.5−x)=−1.5(Distribute the Negative Sign)
x+−6+(−1)(4.5)+−1(−x)=−1.5
x+−6+−4.5+x=−1.5
(x+x)+(−6+−4.5)=−1.5(Combine Like Terms)
2x+−10.5=−1.5
2x−10.5=−1.5
Step 2: Add 10.5 to both sides.
2x−10.5+10.5=−1.5+10.5
2x=9
Step 3: Divide both sides by 2.
2x/2=9/2
x=9/2
Answer is 9/2.
2. When you take a taxi, the driver charges an initial fee

every mile driven in the cab. If the total fare for a cab
ride is 3.5m + 2.5 after riding for m miles, what does the
2.5 represent? Explain (use appropriate math
vocabulary in your explanation).
Answers
Answer:
The
3
mile cab ride includes a basic charge as well as the cost for the distance covered.
For a
6
mile trip, the cost is
$
4.80
which means that :
The cost of
3
miles is
$
4.80

3.00
=

1.80
Therefore the cost for
1

=

0.60
The basic fee for hiring the cab is
$
3.00

Answers
Answer:

Step-by-step explanation:
(f+g) = f(x) + g(x)
Therefore, x + (f+g) = x + f(x) + g(x)
If you are given equations to go with f(x) and g(x), you would plug in those equations to the above expression then combine like terms to find the fully simplified expression equal to x + (f+g).

A. 721 cubic units
B. 21617 Cubic units
C. 64817 cubic units
D.8641 cubic units
Answers
Answer: I hope this helps!
Step-by-step explanation:
The volume of cone having diameter 18 units and height 8 units is 678.85 cubic units which is nearest to 648.17 cubic units which is option C.
What is volume?Volume is basically amount of substance a container can hold in its capacity. Volume of cone is 1/3 *π[tex]R^{2}H[/tex] in which R is the radius and H is height of cone.
How to find volume?We know that volume of cone is 1/3 *π*[tex]R^{2} H[/tex]
We have to put the value of radius and height in the formula to get the value of volume of cone.
Radius=diameter/2
=18/2
=9 units.
Volume=1/3 * 3.14*9*9*8
=2034.72/3
=678.24 cubic units
Nearest option is 648.17 cubic units.
Hence the volume of the cone is 648.17 units.
