A line is perpendicular to the line given by the equation - 8 = 2y + 3x. What is the slope of the perpendicular line? 3
Answer:
2/3 is the slope of the perpendicular line
Step-by-step explanation:
1) put into slope-intercept form (y=mx+b)
-8=2y+3x
-2y=3x+8
y=-3/2x-4
2) the line is perpendicular so the slope will be opposite and the reciprical of the original slope.
so, because the original was -3/2, the new one is 2/3
Consider the polynomial function
g(x) = -x^4 + 2x^3 + 5x^2 – 1.
What is the end behavior of the graph of g ?
Answer: as x > infinity, g(x)> - infinity and as x> - infinity, g(x)> - infinity
Step-by-step explanation:
Left and right ends of the given poynomial function will fall downwards (towards negative infinity).
End behavior of a polynomial: If a polynomial function is f(x) = ax⁴ + bx³ + cx² + dx + eLeading coefficient → a
Degree of the polynomial = 4
If the degree is even and leading coefficient is negative (-), left end and right ends fall downwards.Given in the question,
Poynomial function → g(x) = -x⁴ + 2x³ + 5x² - 1
Degree of the polynomial = 4 (even)
Leading coefficient = -1 (negative)
Therefore, left end of the graph will fall downwards (towards negative infinity) and the right end of the graph will fall downward (towards negative infinity).

The moon forms a right triangle with the Earth and the Sun during one of its phases, as shown below: A right angle triangle is shown with the Earth at the right angle. The acute angle between the line joining the Earth and the S The moon is, on average 238,900 miles from the Earth and the Sun is roughly 93,000,000 miles from the Earth. What is the measure of angle x? Round to the nearest hundredth. Note. This is a very small angle.
Answer:
0.15
Step-by-step explanation:
Using trigonometry :
Tanθ = opposite / Adjacent
Opposite = distance between earth and sun = 238,900
Adjacent = distance between earth and moon = 93,000,000
Tanx = 238900 / 93000000
Tanx = 0.0025688
x = tan^-1 (0.0025688)
= 0.1471820°

Answer:
Slope formula: y2-y1/x2-x1
Step-by-step explanation:
8-6/9-6= 2/0
Answer:
Step-by-step explanation:
Alright we need to prove that both the triangles are similar so lets get started
The slope formula is:
Slope = Change in y / Change in x
m = Δy / Δx
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]
Where, m is the slope and [tex](x_1,y_1) , (x_2,y_2)\\[/tex] are any points on the line
In this graph we are given three points which are
(0 , 2) , ( 6 , 6) and (9 , 8)
So for our first triangle we use the 2 points (0 , 2) and (6 ,6) and calculate the slope,
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{6-2}{6-0}\\\\m=4/6\\\\m=2/3\\[/tex]
So the slope turns out to be 2/3 , Now for our second triangle use the 2 points (6 , 6) and (9 , 8)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-6}{9-6}\\\\m=2/3\\[/tex]
So we can see the the slope's are equal that's the answer to your first part.
Second part
Yes they are similar due to the property of corresponding angles where angle x of the first triangle equals angle x for the second triangle and angle y for the first triangle equals angle y for the second triangle and both the triangles have 90° se they are similar because all three angles are similar. (AAA = angle angle angle property) I have attached a to make you understand it better.

Which number is equal to the expression 7 x 104 + 3 x 103 + 0 x 102 + 8 x 101 + 5 ?
Answer:
1
Step-by-step explanation:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation

Answer:
x = 1
Step-by-step explanation:
3(x + 6) -5 = 16
You want to first add the 5 (*flipping the sign) over to the 16
making your equation ...
3(x +6) = 21
Then you want to distribute the 3 to x and 6
making you equation
3x + 18 = 21
Then you want to subtract the 18 (*flipping the sign) to the right side
making the equation....
3x = 3
Lastly, divide the 3 on the left to the 3 on the right making the answer 1
x = 1

Jericho wants to start saving to
purchase a house. His goal is to save $92,400. If he deposits $56,000 into an account that pays 2.92% interest compounded daily, approximately how long will it take for his money to grow to the desired amount? Round your answer to the nearest tenth of a year.
a) 19.3 years
b) 21.7 years
c) 15.4 years
d) 17.2 years
Answer:
its B
Step-by-step explanation:
If he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that,
Principal(P) = $56,000
Rate(R) = 2.92%
Time(T) = x years
Interest(I)=?
The amount to be collected to save the money is,
=$92,400 - $56,000
=$36,400
Interest = $36,400
The formula for the simple interest is,
I=(P×R×T)/100
Substitute the given value as
[tex]\rm 36400=\frac{\left(56000\times \:2.92T\right)}{100} \\\\ \frac{\left(56000\times \:2.92T\right)}{100}=36400 \\\\ \frac{100\times \:56000\times \:2.92T}{100}=36400\times \:100 \\\\ 163520T=3640000 \\\\ T=\frac{1625}{73} \\\\ T=21.7 \ years[/tex]
Thus, if he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.

A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 113 larger, by what is the percent of increase in the area of the picture
Answer:
27.7% larger
Step-by-step explanation:
6 x 113% = 6.78
9 x 113% = 10.17
Old Area = 9 x 6 = 54 sq in
New Area = 6.78 x 10.17 = 68.95
(New - Old) ÷ Old = .277 = 27.7%
