Answer:
HL
Step-by-step explanation:
By the reflexive property of congruence, NL is congruent to NL. Note that NL is a leg shared by both triangles. Next, we can see that the two hypotenuses of the triangles are marked as congruent. This is enough information to prove that NKL is congruent to NJL by the HL congruence theorem.

A building contractor estimates that her profit in dollars for a tall building will be given by the function:
P (h) = -4h2 + 160h,
where h represents the numer of floors in the buliding.
What height will give the maximum profit? What is the maximum profit?
Question to answer: What is the maximum profit?
profit is———
dollars
Answers
Answer:
The height is 20
The max profit is 1600
Step-by-step explanation:
P (h) = -4h^2 + 160h
The vertex is at
-b/2a = -160/2(-4) = 160/8 = 20
The height that will give the maximum profit is 20
We want to find the value at 20
P(40) =-4(20)^2 +160(20)
=-1600+3200
1600
If b=13 and A=76 degrees, then find a.
Answers
Answer:
Option (D).
Step-by-step explanation:
In the figure attached,
Triangle ACB is a right triangle having,
Leg AC = b = 13
Leg BC = a
Angle A = 76°
and, Hypotenuse AB = c
By applying tan rule in the given triangle,
tanA = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(76)° = [tex]\frac{BC}{AB}[/tex]
= [tex]\frac{a}{b}[/tex]
4.01 = [tex]\frac{a}{13}[/tex]
a = 13 × 4.01
a = 52.13
a ≈ 52.1
Therefore, Option (D). will be the answer.

Answers
Answer:
x = -2 ±sqrt( 19)
Step-by-step explanation:
x^2 + 4x = 15
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 = 4
Add it to each side
x^2 + 4x+4 = 15+4
(x+2)^2 = 19
Take the square root of each side
sqrt( (x+2)^2) =±sqrt( 19)
x+2 = ±sqrt( 19)
Subtract 2 from each side
x+2-2 = -2 ±sqrt( 19)
x = -2 ±sqrt( 19)

Which of the statements about the diagram is INCORRECT?
A) ∠ 1 ≅ ∠2
B) BE ≅ ED
C) BE ≅ CE
D) CE ≅ EA
Answers
Answer:
C) BE ≅ CE
Step-by-step explanation:
[tex]\triangle BEA \cong \triangle DEC\\BE \ncong CE\\[/tex]
Because BE and CE are not corresponding sides.
The corresponding sides and angles of a congruent triangle are congruent.
(c) [tex]\mathbf{\angle BE \cong CE}[/tex] is incorrect
From the question, triangles BEA and CED are congruent.
This means that, the following statements are true
[tex]\mathbf{BE \cong ED}[/tex].[tex]\mathbf{CE \cong EA}[/tex].[tex]\mathbf{\angle 1 \cong \angle 2}[/tex].The above statements represent options (a), (b) and (d).
This means that:
[tex]\mathbf{\angle BE \cong CE}[/tex] is incorrect
This is so because, BE and CE are not corresponding sides.
Hence, (c) [tex]\mathbf{\angle BE \cong CE}[/tex] is incorrect

Box A = 2 × 1/2 = 1
Box B = 1 × 1 = 1
Box A= L x B x H

Box B = L x B x H
= 1 x 1 x 2.5

Hence Box A has more storage space since it’s volume is higher
If tan a = 9／40
use trigonometric identities to find the values of sin a and cos a.
Answers
Answer:
see explanation
Step-by-step explanation:
Given
tan a = [tex]\frac{9}{40}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = [tex]\sqrt{1681}[/tex] = 41 , thus
sin a = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9}{41}[/tex]
cos a = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{40}{41}[/tex]

Step-by-step explanation:
In this question, we are to rewrite (2/5)/(1/2) as unit rate.
To write this as a unit rate, what we need to do
is to divide 2/5 by 1/2.
That means 2/5 divided by 1/2
Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Answers
Answer:
Let's solve your equation
[tex]x^2+13=8x+37[/tex]
Step 1: Subtract 8x+37 from both sides.
[tex]x^2+13-(8x+37)=8x+37-(8x+37)[/tex]
[tex]x^2-8x-24=0[/tex]
For this equation: a= 1, b= -8, c= -24
Step 2: Use quadratic formula with a=1, b=-8, c=-24.
[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]
[tex]x=\frac{-(-8)+\sqrt{(-8)^2-4(1)(-24)} }{2(1)}[/tex]
[tex]x=\frac{8+\sqrt{160} }{2}[/tex]
[tex]x=4+2\sqrt{10}[/tex] or [tex]x=4-2\sqrt{10}[/tex] This is the answer
So,the correct option is C
