Given:
−4(x+3)−12x+5
Use distributive property and simplify.
= -4x - 4(3) - 12x + 5
= -4x - 12 - 12x + 5
Combine like terms.
= -4x - 12x - 12 + 5
= -16x + 7

13. In isosceles triangle HMS, ZM is the vertex angle.
If m2M = (2x + 6)° and mZH (9x + 7)º, what
is mZM?
A. 10°
B. 22°
C. 79°
D. 80°
Answer:
B.[tex]22^{\circ}[/tex]
Step-by-step explanation:
We are given that HMS is an isosceles triangle.
Angle M is the vertex angle.
[tex]m\angle M=(2x+6)^{\circ}[/tex]
[tex]m\angle H=(9x+7)^{\circ}[/tex]
[tex]\angle H=\angle S[/tex]
By definition of isosceles triangle
We have to find the measure of angle M.
[tex]\angle M+\angle H+\angle S=180^{\circ}[/tex]
By using sum of angles of triangle property
Substitute the values
[tex]2x+6+9x+7+9x+7=180[/tex]
[tex]20x+20=180[/tex]
[tex]20x=180-20[/tex]
[tex]20x=160[/tex]
[tex]x=\frac{160}{20}=8[/tex]
Using the value of x
[tex]m\angle M=2(8)+6[/tex]
[tex]m\angle M=22^{\circ}[/tex]
Hence, option B is correct.

The table shows the depths of four plants.
Order the numbers from least to greatest.
Answer:
-20 3/4, - 15 1/2, - 14 3/4, - 1/4
Step-by-step explanation:
Given the depths :
-14 3/4, - 15 1/2, - 1/4, - 20 3/4
Ordering from least to greatest :
Since the numbers are negative; arranging the numbers as it would appear on a number line ; Large whole number negative values are always the least.
-20 3/4, - 15 1/2, - 14 3/4, - 1/4

Given the function f(x) = 4^x - 1, explain and show how to find the average rate of change between x = 1 and x = 4.
Answer:
84
Step-by-step explanation:
f(1)=4^1 - 1 = 3
f(4) = 4^4 - 1 = 255
rate of change = [tex]\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
(255 - 3) / (4 - 1) = 252 / 3 = 84

In a chemistry lab, there are 9.52 grams of a powdered substance in a container. Max needs to place an equal amount of the powdered substance into each of 3 glass plates. The amount of powdered substance he places into each glass plate is 1.98 grams.
Max estimates that there are about 4.5 grams of the powdered substance remaining in the container. Is his statement reasonable?
A.
This is not reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 1 gram. Since 9 − 3(1) = 6, there would be about 6 grams of the powdered substance remaining in the container.
B.
This is reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 2.5 grams. Since 9 − 3(2.5) = 1.5, there would be about 1.5 grams of the powdered substance remaining in the container.
C.
This is not reasonable because 9.52 grams can be rounded to 9.5 grams and 1.98 grams can be rounded to 2 grams. Since 9.5 − 3(2) = 3.5, there would be about 3.5 grams of the powdered substance remaining in the container.
D.
This is reasonable because 9.52 grams can be rounded to 9 grams and 1.98 grams can be rounded to 1.5 grams. Since 9 − 3(1.5) = 4.5, there would be about 4.5 grams of the powdered substance remaining in the container.
C
Step-by-step explanation:
I would have to say C. Even if you went with just the explainations, the math just adds up to 3.5
9.52 grams total
1.98 x 3 = 5.94 in total in all the containers
9.52 in the container
- 5.94 being taken out
3.58 left remaining in the jar

a circle has a radius of 15 centimeters and a central angle that measures 175 degrees. find the length of the arc defined by this central angle. leave your answers in terms of pi. NEED ASAP
Answer:
14.58π cm to the nearest hundredth.
Step-by-step explanation:
Circumference of the circle = 2 π r
= 30π
By proportion the length of the arc defined by 175 degrees
= 30 π * 175 / 360
= 14.58 π cm.

A motorboat travels 385 kilometers in 7 hours going upstream and 455 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answer:
Rate of the boat in still water 73 mi/hr
Rate of the current 18 mi/hr
Step-by-step explanation:
Calculation to determine the rate of the boat in still water and the rate of the current
Let B represent the speed of the boat in still water.
Let S represent the speed of the stream
Speed upstream = B-S.
Speed downstream = B+S.
Using the equation for distance
Distance=Rate * Time
Upstream
(B-S)7 = 385
(B+S)5= 455
Simplify first:
B-S=385/7
B-S = 55
B+S=455/5
B+S = 91
Solve by elimination. Add the two equations.
2B=55+91
2B = 146
B=146/2
B = 73 mi/hr
Substitute this into either equation and solve for S.
B+S = 91
73+S = 91
S=91-73
S = 18 mi/hr
Therefore the rate of the boat in still water is 73 mi/hr and the rate of the current is 18 mi/hr

Part B: What is an approximate average rate of change of the graph from x = 1 to x = 4, and what does this rate represent? (3 points)
Part C: Describe the constraints of the domain. (3 points)
Answer:
A) intercept: 0 profit : Maximum(max) : max profit. increasing x <4 ; decreasing x > 4
B) average slope: ≈50, about $50 increasing profit for each $1 increasing in price.

An artist is laying out the design for a wall hanging on a coordinate plane. She uses polygon EFGH with vertices E (4, 4), F (−4, 4), G (−4, −4), and H (4, −4) to represent the finished piece. What is the area of this polygon?
Answer:
The area is 64squared units
Step-by-step explanation:
Given
[tex]E = (4,4)[/tex]
[tex]F = (-4,4)[/tex]
[tex]G = (-4,-4)[/tex]
[tex]H = (4,-4)[/tex]
Required
The area of the polygon
First, we plot the given coordinates on a plane (See attachment)
From the attachment, we can see that the 4 coordinates make up a square.
Where
[tex]EF = FG = GH = GE = 8\ units[/tex]
So, the area is:
[tex]Area = EF^2[/tex]
Substitute [tex]8[/tex] for [tex]EF[/tex]
[tex]Area = 8^2[/tex]
[tex]Area = 64[/tex]
Hence, the area is 64 squared units

A. Russell is 5'9". What is the probability he is a forward?
B. Peter is 6'2". What is the probability he is a guard?
Answer:
0.324
0.068
Step-by-step explanation:
If Russell is 5'9" ; then he is under 6 feets :
Probability = number of forwards under 6 feets / tot number of players
Probability = 120 / 370 = 0.324
Peter is 6'2" ; Peter is over 6 feets ;
Probability that Peter is a guard = (number of guards over 6 feets / total number of players) = 25 / 370 = 0.0676 = 0.068

Please help me find the answer
Answer:
in the first traingle
sinC = 36/39 = 12/13
CosC= 15/39 = 5/13
TanA= 15/36=5/12
this is the values i didnt understand the question so i just find the values
in the second Triangle
SinA=2√5/5
CosA=√5/5
TanB= √5/2√5=1/2
cos 30 = √3/2
sin45=√2/2
tan60= √3
hopefully its helpful iam sorry i didnt understand what they mean in the question my engilish is bad
Sin of c. Sin'-1(36/39)=90
Cos of c cos'-1(15/39)=67.38
Tan of a tan'-1(15/36)=22.62
Sin of a sin'-1(2squarroot5/5)=63.43
Cos od a cos'-1(squareroot5/5)=63.43
Tan of b tan'-1(2squareroot5/squareroot5)=63.43
Cos30 is pie/6 or squareroot of 3 /2
Sin of 45 is pie/4 or squareroot2/2
Tan60 is pie/3 or squareroot3
