Determine whether the Law of Cosines or the Law of Sines is needed to solve the triangle a = 11, b = 13, c = 7
Answer:
Step-by-step explanation:
Use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cos C becomes
7^2 = 11^2 + 13^2 - 2(11)(13)cos C.
Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.
6. Which equation written in slope-intercept form represents the trend line 1 shown on the scatter plot below?
9514 1404 393
Answer:
B
Step-by-step explanation:
The line has a y-intercept of 40 (in agreement with all answer choices). It goes through the point (6, 30), so has a "rise" of -10 for a "run" of 6. The slope is ...
m = rise/run = -10/6 = -5/3
The equation with a slope of -5/3 is the one shown in choice B.
Answer:
B

A data set is normally distributed with a mean of 27 and a standard deviation of 3.5.
Find the.z-score for a value of 25, to the nearest hundredth.
Answer: -0.57
Step-by-step explanation:
z-score: data - mean / standard deviation
25 - 27 / 3.5
= -0.57

Question 1
Which statement about the system of equations y = 3x + 9 and y = 3x – 4 is true?
A. No solution
B. Infinite solutions
C. Exactly one solution
D. Different y-intercepts so there are two solutions
Answer:
A. no solution
Step-by-step explanation:
y = 3x + 9
y = 3x - 4
Let's solve this.
We can see that both equations equal y, so we can set them equal to each other.
3x + 9 = 3x - 4
Combine like terms.
[add 4 to both sides]
3x + 13 = 3x
[subtract 3x from both sides]
13 = 0
This statement is not true; therefore, there is no solution.
If we look at the graph below, we can see the lines are parallel. Parallel lines will never intersect and have no solution in a system of equations.
Hope this helps!
Solve for x. Enter the solutions from least to greatest. Round to two decimal places. (x + 8)^2 - 7 = 0
Answer:
x
= − 5.35424868 , − 10.64575131
Step-by-step explanation:
Answer:
Step-by-step explanation:
(x+8)^2=7
(x+8) = [tex]\pm \sqrt7[/tex]
x = [tex]\sqrt7[/tex]-8 and -8-[tex]\sqrt7[/tex]
which is about -10.65 and -5.35
What is the volume of the Cylinder ? Use 3 14 round the answer to the nearest hundredth . h = 7in r = 7in
Answer:
V = 1077.02 in³
Step-by-step explanation:
To find the volume of a cylinder, we use this formula:
V = πr²h
Let's plug in what we know.
V = (3.14)(7)²(7)
Evaluate the exponent first.
V = (3.14)(49)(7)
Multiply.
V = 1077.02 in³
Hope this helps!
Find m
Someone pleaseee helppAnswer:
107°
Step-by-step explanation:
m∠m+m∠p= 180°
(7x+31)°(21x-19)°=180°
7x+31+21x-19= 180
7x+21x=180+19-31
28x=168
x= 168/28
x= 6
m∠p= (21x-19)°
= (21(16)-19)°=(126-19)°
= 107°
------------
hope it helps..

Sandra buys stamps that cost $0.65 each. She spends a total of $158.60 on the stamps. To determine how many stamps she buys, she needs to divide $158.60 by $0.65.
How many stamps does Sandra buy?
Answer:
1 Stamp = $0.65
Stamps Bought= $158.60/0.65
=244 Stamps
An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole from the eagle(diagonal) to the nearest tenth of a foot?
Answer:
[tex]X=49ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of Eagle [tex]h=40ft[/tex]
Angle of depression [tex]\theta=35\textdegree[/tex]
Generally the trigonometry equation for diagonal X is mathematically given by
[tex]Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }[/tex]
[tex]Cos\theta \textdegree=\frac{h}{X} }[/tex]
[tex]X=\frac{40}{Cos 35 } }[/tex]
[tex]X=48.83ft[/tex]
[tex]X=49ft[/tex]
