Answer:
-x^5+2x³-x²-1x-1
Step-by-step explanation:
First order the terms based on highest degree or exponent.
-x^5+2x³-x²-3x¹+2x-1
Next combine like terms.
-3x¹ is simply -3x so -3x+2x = -1x
-x^5+2x³-x²-1x-1
In a model, the distance from the sun to Earth is 7 inches and the distance from the sun to Neptune is 19 inches. If the actual distance from the sun to Earth is 91.549 million miles and the actual distance from the sun to Neptune is 2,780.5 million miles, are the model’s distances proportional to the actual dimensions of the solar system?(1 point)
Responses
Yes, because the ratios of model length to actual distance are equal for the two planets.
Yes, because the ratios of model length to actual distance are equal for the two planets.
No, because the ratios of model length to actual distance are different for the two planets.
No, because the ratios of model length to actual distance are different for the two planets.
No, because the model is in inches and the actual distances are in millions of miles.
No, because the model is in inches and the actual distances are in millions of miles.
No, because the ratios cannot be reduced.
The model’s distances isn't proportional to the actual dimensions of the solar system as B. No, because the ratios of model length to actual distance are different for the two planets.
What is ratio?Ratio demonstrates how many times one number can fit into another number. It is used to show the comparison between two or more things
In this case, in model, the distance from the sun to Earth is 7 inches and the distance from the sun to Neptune is 19 inches. This can be illustrated as:
= 7/19
= 0.368
If the actual distance from the sun to Earth is 91.549 million miles and the actual distance from the sun to Neptune is 2,780.5 million miles, the ratio is:
= 91.549 / 2780.5
= 0.0329
Therefore, since they're different numbers, the information doesn't illustrate a proportional ratio.

Answer:
NOT CONGRUENT
Step-by-step explanation:
There are several types of congruence:
ASA - Angle Side Angle
AAS - Angle Angle Side
HL - Hypotenuse Leg
This image shows two triangles which have 2 congruent sides and one congruent angle.
Is it ASA?
There is only one congruent angle, so this cannot be congruent by ASA
Is it AAS?
By the same reasoning, it cannot be congruent by AAS.
Is it HL?
Although there are 2 congruent sides, neither one is the hypotenuse. Is is not congruent by HL.
There is no such thing as SSA congruence, because it is actually possible to have 2 non-congruent triangles who have 2 congruent sides and 1 congruent angle. Therefore, these are NOT CONGRUENT
Which pair of lines are perpendicular?
A. y = -8 and y = 2
B. x = 4 and y = -1
C. x-y = 7 and y = x + 3
D. y = -4x + 1 and 8x + 2y = -10
Applying the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.
There are 4 different pairs of lines given to us.
We have to find out the pair of lines that are perpendicular to each other.
We know that the general equation of a line in slope-intercept form is represented as -
y = mx + c --- (1)
where
(x, y) = coordinates of the lines
m = slope of the line
c = y-intercept
It is also known to us that for two lines to be perpendicular the product of their slope must be equal to -1.
A. y = -8 and y = 2
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
B. x = 4 and y = -1
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
C. x - y = 7 and y = x + 3
Now, x - y = 7
=> -y = 7 - x
=> y = x - 7
Comparing this to the equation (1), we have slope of the line, m = 1.
Also, y = x + 3
Comparing this to the equation (1), we have slope of the line, m = 1.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
D. y = -4x + 1 and 8x + 2y = -10
Now, y = -4x +1
Comparing this to the equation (1), we have slope of the line, m = -4.
Also, 8x + 2y = -10
=> 2y = -8x - 10
=> y = -4x - 10
Comparing this to the equation (1), we have slope of the line, m = -4.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
Thus, according to the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.

The area of each of the following shaded regions in parts (a)-(d) is 2
How Find the area of each of the following shaded regions?There is a space in the shaded area. Because we are given two circles inside one larger circle, the size of the darkened zone is equal to the area of the circle less the area of the circle.
They are equal to the circle to an area of circle minus an area of circle three. You can calculate the radius of the larger circle as this is likewise 1 cm. The radius refers to the location of the larger circle's center. Keep in mind that all measurements are in cm square. C2's surface area is the same as that of three.There will only be one square. The area is located in the area that is darkened. The region is equal to the size of C1 minus the areas of C2 and C3. As a result, C will be the first. C 2 and C three are the same, and the area is four pi.The answer is 2, and square meters are not the appropriate unit.

A grocer mixes two kinds of n ur s. One kind costs $5.00/kg and the other $5.80/kg. How many kilograms of each type are needed to make 40kg of a blend worth $5.50/kg?
15 kilograms of the first type should be mixed with 25 kilograms of the other kind
How to determine the kilograms of each type needed to make 40kg?If the blend costs $5.50/kg, then:
on each kg at $5.00/kg, gain = $0.50 ($5.50 - $5.00)
on each kg at $5.80/kg, loss = $0.30 ($5.50 - $5.80)
Hence 3kg of the first kind must be mixed with 5kg of the second so that the gain on the first (3 x $0.50) is exactly the same as the loss on the second (5 x $0.30)
The required proportion is 3:5
In order to find how many kilograms of each type are needed to make 40kg, we will use the proportion obtained:
We have 3:5, total share = 3+5 = 8
First kind share = 3/8 x 40 kg = 15 kg
Second kind share = 5/8 x 40 kg = 25kg
Therefore, 15 kilograms of the first type is needed and 25 kilograms of the other kind is needed

What is Simple Interest?
Simple interest is a quick and simple way to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of many forms of interest that banks charge. Now, let's first clarify what a loan is before delving further into the idea of simple interest. A loan is a sum of money that someone borrows from a bank or other financial institution to cover expenses. Home loans, auto loans, student loans, and personal loans are a few instances of loans.
In the given question we have:
Principal amount = 7000$,
Rate of interest r = 7.5%,
Time t = 15 months;
So, applying the formula to calculate simple Interest:
S.I = [tex]\frac{PRT}{100}[/tex]
S.I = [tex]\frac{7000 \times 7.5 \times 15}{ 12 \times 100}[/tex]

from the highway. Once she gets on the highway she maintains a constant rate for
several hours. Complete the table of values for the sequence below that relates hours on
the highway and distance from the warehouse in miles.
Refer to the attachment for the required table:
What is the unit rate?
A unit rate is a cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.
From the table,
For 0 hours, distance = 15 miles
For 1 hour, distance = 80 miles
Difference between distances= 80-15=65 miles
Since it is given that, it is at a constant rate, for every hour there is an increase of 65 miles in distance.
