Answer:
[tex]C = (\frac{33}{5},\frac{19}{5})[/tex]
Step-by-step explanation:
Given
[tex]A = (1,3)[/tex]
[tex]B = (8,4)[/tex]
[tex]AC : BC = 4 : 1[/tex]
Required
Determine the coordinates of C
To do this, we make use of:
[tex]C = (\frac{nx_1 + mx_2}{n+m},\frac{ny_1 + my_2}{n+m})[/tex]
Where:
[tex]A = (1,3)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]B = (8,4)[/tex] ---- [tex](x_2,y_2)[/tex]
[tex]m:n = 4 : 1[/tex]
So:
[tex]C = (\frac{1 * 1 + 4*8}{1+4},\frac{1*3 + 4*4}{1+4})[/tex]
[tex]C = (\frac{33}{5},\frac{19}{5})[/tex]

3. The measure of an interior angle of a regular polygon is 140. Find the number of sides the polygon has.
Answer:
I hope this will help u
Step-by-step explanation:
Each interior angle of a regular polygon = 140 deg. So each exterior angle of the regular polygon = 180-140 = 40 deg. Hence the regular polygon has 360/40 = 9 sides.

Your test scores in one class are 79 and 83. What possible scores can you earn on your next test to have a test average between 81 and 87, inclusive?
Answer:
83 and 84
Step-by-step explanation:
these numbers will both work because if you make an equation 79+83+x=y, with 87≥y≥81, and plug in these numbers for x, the answers are around 82 which is within the range.
In a right triangle when a = 8 and b = 15, what is the measure of c? ill give brainlist asap HELP!!!!!
Answer: 17
Step-by-step explanation:
To answer this question you can use the Pythagorean theorem which is a^2 + b^2=c^2. Plugging in the values you get 8^2 + 15^2=c^2. 8 times 8 is 64 and 15 times 15 is 225. 64+225=289. That leaves 289=c^2. Then find the square root of both numbers which leaves you with 17=c
Answer:
[tex]\boxed {\boxed {\sf c=17}}[/tex]
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse.
We know that a is 8 and b is 15. We don't know the measure of c.
[tex]a=8 \\b=15[/tex]
Substitute the values into the formula.
[tex](8)^2+(15)^2=c^2[/tex]
Solve the exponents.
(8)²= 8*8=64 (15)²= 15*15=225[tex]64+225=c^2[/tex]
Add on the left side.
[tex]289=c^2[/tex]
Take the square root of both sides. This "cancels out" the exponent of 2 and isolates the variable.
[tex]\sqrt {289}=\sqrt{c^2}\\\sqrt{289}=c\\17=c[/tex]
The measure of c is 17.

2 3/4 yards of fabric for $22 express as unit rate. round to nearest cent if necessary
Answer:
7
Step-by-step explanation:
Answer:
13(rounded) cents per 1/4 yard and 50 cents per yard
Step-by-step explanation:
Step 1: Convert the mixed fraction into an improper fraction
[tex]2\frac{3}{4} = \frac{4}{4}+\frac{4}{4}+\frac{3}{4}[/tex]
[tex]2\frac{3}{4}=\frac{11}{4}[/tex]
Step 2: Find the unit price per 1/4 yard
[tex]\frac{11}{4}/22[/tex]
[tex]0.125 = 13 \ cents[/tex]
Step 3: Find the unit price per 1 yard
[tex]12.5\ cents\ per\ 1/4\ yard=50\ cents\ per\ 1\ yard[/tex]
Answer: 13(rounded) cents per 1/4 yard and 50 cents per yard
The graph of f(x) = x2 was transformed tu
create the graph of d(x) = f(x) + 9. Which of
the following attributes will be the same for the
graphs f(x) and d(x)?
1. the domain
11. the range
III. the axis of symmetry
Answer:
i: the domain.
iii: the axis of symmetry.
Step-by-step explanation:
We have the function:
f(x) = x^2
The domain of this function is the set of all real numbers, and the range is:
R: [0, ∞)
(because 0 is the minimum of x^2)
Now we have the transformation:
d(x) = f(x) + 9 = x^2 + 9
Notice that this is only a vertical translation of 9 units, then there is no horizontal movement, then the axis of symmetry does not change.
Also, in d(x) there is no value of x that makes a problem, so the domain is the set of all real numbers, then the domain does not change.
And d(x) = x^2 + 9 has the minimum at x = 0, then the minimum is:
d(0) = 0^2 + 9 = 9
Then the range is:
R: [9, ∞)
Then the range changes.
So we can conclude that the attributes that will be the same for f(x) and d(x) are:
i: the domain.
iii: the axis of symmetry.

Answer:
396 Square feet
Step-by-step explanation:
1.) First find the side closest to you. 6 x 12 = 72. Then double it to match the parallel side. 72 x 2 = 144
2. Find the side to the right and left, 7 x 6 = 42. Then double it to match the parallel side. 42 x 2 =84
3.) Find the top side and bottom side. 12 x 7 = 84. Then double it to match the parallel side. 84 x 2 = 168
4.) Find the total surface area. 144+84+168=
5.) The total surface area is 396 square feet

5x + 4 = 3x + 10 how would you solve for the value of x? How would you prove your solution is correct? How would you prove another value is incorrect? Explain in as much detail as possible.
5x+3=3x+10 the first thing we're going to do it to subtract 3 from both sides which would look like this
5x+3-3x=10 (the minus because it changed place)
from 5x and 3x we get 2x so the next step is 2x=10-3 which is 7
so now we have
2x=7
x=7/2
Answer:
x=3
Step-by-step explanation:
5x+4 = 3x+10
2x = 6
therefore, x = 3
Verification:
5 * 3 + 4 = 3 * 3 + 10
15+4 = 9+10
19=19
Therefore, LHS= RHS
Hence Proved!

Find the value of x on a triangle
Answer:
x = 25
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees.
90 + x+ 2x+15 =180
Combine like terms
105+3x = 180
Subtract 105 from each side
105+3x-105 = 180-105
3x =75
Divide each side by 3
3x/3 = 75/3
x = 25
Answer:
25°
Step-by-step explanation:
2x + 15° + x + 90 °= 180° ( being sum of angles of triangle)3x + 105° = 180 °3x = 180 °- 105°3x = 75° x = 25°hope it helps :)Can someone please help me I’m desperate it due tomorrowwww

WILL MARK BRAINLIEST! Solve for x and each angles measure. Only asking for #5. Thank you!
Answer:
Step-by-step explanation:
2x + 3x + 135 = 180 Every triangle has 180 degrees
5x + 135 = 180 Subtract 135 from both sides.
5x = 45 Divide by 5
x = 9
2x = 18
3x = 27
Other angle 135
Total 280
Evaluate f(4) for the function f(x)=3x-5
A.12
B.7
C.9
D.17
the answer is b.7
Step-by-step explanation:
because you have to plug in the f(4) to the equation like this
f(4)=3(4)-5
and then multiple 3x4 which is 12 then subtract 12 and 5 and you get 7.
