A triangle has two angle measures of 20 degrees and 30 degrees. Find the third angle. This triangle is a(n) ________ triangle
Question 2 options:
A. acute
B. obtuse
C. right
D. it does not make a triangle
Answer:
Obtuse
Step-by-step explanation:
x = missing angle
20+30+x=180
50+x=180
x=130
90<130
Thus, the triangle is obtuse

Graph this: y = 2sIn(x) - 3
Insert picture of graph
Answer:
We have the function:
f(x) = 2*sin(x) - 3
To graph this type of functions is useful to understand the parts of the function.
A general one is written as:
g(x) = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency.
p is the phase
M is the midline.
Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3
Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:
What is congruent in this problem?

The rate of change of y is proportional to y. When t = 0, y = 4, and when t = 2, y = 8. What is the value of y when t = 3?
Solution :
Given :
The rate of change of y is proportional to y.
Therefore, [tex]$\frac{dy}{dt} \propto y$[/tex]
[tex]$\frac{dy}{dt} = k y$[/tex] , where k is the proportionality constant
[tex]$\frac{dy}{y}=k \ dt$[/tex]
Taking integration on both the sides,
[tex]$\int \frac{dy}{y}=\int kdt$[/tex]
[tex]$\int \frac{dy}{y}=k\int dt$[/tex]
[tex]$\ln |y| = kt+C$[/tex], where C is the integration constant
[tex]$y=e^{kt+C}$[/tex]
[tex]$y=e^{kT}e^C$[/tex]
[tex]$y(t)=C_1e^{kt}$[/tex] ....................(1)
When t = 0, y = 2, so
[tex]$2=c_1e^{k\times 0}$[/tex]
[tex]$2=c_1e^{ 0}$[/tex]
[tex]$2=C_1$[/tex]
From equation (1),
[tex]$y=2e^{kt}$[/tex] ........................(2)
when t = 2, y = 4
[tex]$4=2e^{k\times 2}$[/tex]
[tex]$e^{2k}=\frac{4}{2}$[/tex]
[tex]$e^{2k}=2$[/tex]
[tex]$2k= \ln(2)$[/tex]
[tex]$k=\frac{1}{2} \ln(2)$[/tex]
From (2),
[tex]$y=2e^{\frac{1}{2}\ln(2)t}$[/tex]
[tex]$y=2e^{\frac{t}{2}\ln(2)}$[/tex]
[tex]$y=2e^{\ln(2)^{t/2}}$[/tex]
[tex]$y=2.2^{t/2}$[/tex]
When t = 3,
[tex]$y = 2 . 2 ^{3/2}$[/tex]
[tex]$y=2[(\sqrt2)^2]^{3/2}$[/tex]
[tex]$y= 2. 2\sqrt2$[/tex]
[tex]$y=4 \sqrt2$[/tex]

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.
Answer:
14 tons of sugar
$9603.5
Step-by-step explanation:
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Let
x = ton of sugar
Company A:
7500 + 150.25x
Company B:
7143 + 175.75x
1. Equate company A and company B
7500 + 150.25x = 7143 + 175.75x
7500 - 7143 = 175.75x - 150.25x
357 = 25.50x
x = 357/25.50
x = 14 tons of sugar
2. Cost when both companies charge the same
Company B:
7143 + 175.75x
= 7143 + 175.75(14)
= 7143 + 2460.5
= 9603.5
Company B = $9603.5
Company A:
7500 + 150.25x
= 7500 + 150.25(14)
= 7500 + 2103.5
= 9603.5
Company A = $9603.5

A rectangular prism has a volume of 80 cubic feet. The length of the prism is 8 feet and the height of prism is 4 feet. What is the width of the prism?
Answer:
2.5
Step-by-step explanation:
8 times 4 is 32, and 80/32 is 2.5. When you have to find another measurement and you know 2 of them, you just have to divide the total of the 2 measurements with the volume. it would be 2.5 feet as the height.

Consider the line 7x+8y=-5.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
Step-by-step explanation:
7x + 8y = -5
8y = -7x - 5
Divide the whole equation by 8
[tex]\frac{8y}{8}=\frac{-7x}{8}-\frac{5}{8}\\\\y =\frac{-7}{8}x-\frac{5}{8}[/tex]
Parallel lines have same slope
Slope of the parallel line = (-7/8)
Slope of the line perpendicular to this line = -1/m = -1 ÷ (-7/8)
[tex]= (-1)*\frac{8}{-7}\\\\= \frac{8}{7}[/tex]

What will be the linear equation for the shown table?
Answer:
y=2x+5
Step-by-step explanation:
To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)
So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2
Slope = 2, now find b
So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5
Put it all together y = 2x + 5

You charge $2 per square yard to paint.Which equation can you solve to find the amount you will charge to paint a triangular wall with a base of 4 yards and a height of 6 yards?
Answer:
2(1/2 x 4 x 6) = x
expaination:
area of triangle = 1/2 x 2 x 6 sq yards
multiply by $2/sq yard
Answer: $24
Step-by-step explanation:
The formula for a triangle is 1/2 times base times height
so 0.5 x 4 x 6
0.5 x 4 = 2
2 x 6 = 12
12 x $2 = 24
so you charge $24 dollars
Hope this helps.
