How does a dilation affect the side lengths and angle measures of a figure?
After the dilation, the lengths are multiplied by the value of the scale factor while the angles remain same.
What is image dilation?An enlargement or reduction of a figure that preserves shape but not size.All dilations are similar to the original figure.Dilations have a center and a scale factor.Given is to find how dilation affect the side lengths and angle measures of a figure
Assume that the initial length of the figure
After the dilation, the coordinates will become -
(x, y) → (Kx, Ky)
Where {K} is the scale factor by which the image is dilated.
The angles after the dilation remain same.
Therefore, after the dilation, the lengths are multiplied by the value of the scale factor while the angles remain same.

Find A1 in a geometric series for which sn=3045,r=2/5, and an=120
Answer:
a = 1875
Step-by-step explanation:
Sum of geometric series formula:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Geometric series formula:
[tex]a_n=ar^{n-1}[/tex]
Given:
[tex]S_n=3045[/tex][tex]r=\dfrac25=0.4[/tex][tex]a_n=120[/tex][tex]\implies 120=a(0.4)^{n-1}[/tex]
[tex]\implies a=\dfrac{120}{(0.4)^{n-1}}[/tex]
[tex]\implies 3045=\dfrac{a(1-0.4^n)}{1-0.4}[/tex]
[tex]\implies 3045=\dfrac{a(1-0.4^n)}{0.6}[/tex]
[tex]\implies 1827=a(1-0.4^n)[/tex]
[tex]\implies a=\dfrac{1827}{1-0.4^n}[/tex]
Equate equations for a:
[tex]\implies \dfrac{120}{(0.4)^{n-1}}=\dfrac{1827}{1-0.4^n}[/tex]
Apply exponent rule [tex]a^{b-c}=\dfrac{a^b}{a^c}[/tex]
[tex]\implies \dfrac{120}{\frac{0.4^n}{0.4^1}}=\dfrac{1827}{1-0.4^n}[/tex]
[tex]\implies \dfrac{48}{0.4^n}=\dfrac{1827}{1-0.4^n}[/tex]
[tex]\implies 48(1-0.4^n)=1827(0.4^n)[/tex]
[tex]\implies 48-48(0.4^n)=1827(0.4^n)[/tex]
[tex]\implies 48=1875(0.4^n)[/tex]
[tex]\implies 0.4^n=\dfrac{48}{1875}[/tex]
[tex]\implies 0.4^n=0.0256[/tex]
Taking natural logs:
[tex]\implies \ln0.4^n=\ln0.0256[/tex]
[tex]\implies n\ln0.4=\ln0.0256[/tex]
[tex]\implies n=\dfrac{\ln0.0256}{\ln0.4}[/tex]
[tex]\implies n=4[/tex]
Substituting found value for n into one of the equations and solving for a:
[tex]\implies a=\dfrac{120}{(0.4)^{4-1}}[/tex]
[tex]\implies a=\dfrac{120}{0.4^3}[/tex]
[tex]\implies a=\dfrac{120}{0.064}[/tex]
[tex]\implies a=1875[/tex]

Answer:
-60
Step-by-step explanation:
Yeah, of course!.
Step one: Breaking the problem into different problems is probably the best!
Step two: 4× (-1) is simple multiplication, any number multiplied by 1 is always the number. 4 multiplied by 1 is always 4, but there is a negative sign in front of the 1, so that means we have to go into the positive an negative rules, final answer is 4 for that step.
Then were going to ignore the multiplication sign for now.
Step three: (-3) times (-5) is 15 but we have to look at the rules of positives and negatives, a negative plus a negative is a positive. So its 15.
Step four: Multiply the two answers (4 times 15) is 60. Now were going to add our negative sign because a positive plus a positive number is a negative.
Hope this helped! :)

Solve the system of equations by elimination. Express the solution as an ordered pair.
3x−5y=11
x−4y=−8
(12, 5)
equations:
[tex]\sf 3x-5y=11[/tex] ---- equation 1[tex]\sf x-4y=-8[/tex] ---- equation 2To solve with elimination, either the x or y coefficient should be similar.
so we will multiply 3 with the second equation.Then,
[tex]\sf 3x-5y=11[/tex]
[tex]\sf 3x-12y=-24[/tex]
============== [ subtract equation 2 from equation 1 ]
[tex]\sf 7y = 35[/tex]
[tex]\sf y = 5[/tex]
For x,
[tex]\sf 3x-5(5)=11[/tex]
[tex]\sf 3x-25=11[/tex]
[tex]\sf 3x=11+25[/tex]

If f(x) is an exponential function where f(3.5) = 25 and f(8.5) = 14, then find
the value of f(5.5), to the nearest hundredth.
Using an exponential function, it is found that f(5.5) = 19.8.
What is an exponential function?An exponential function is a function in which the growth rate is a percentage, modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value.b is the rate of change.f(3.5) = 25 means that:
[tex]ab^{3.5} = 25[/tex]
[tex]a = \frac{25}{b^{3.5}}[/tex]
f(8.5) = 14 means that:
[tex]ab^{8.5} = 14[/tex]
Hence:
[tex]\frac{25}{b^{3.5}} \times b^{8.5} = 14[/tex]
[tex]25b^5 = 14[/tex]
[tex]b = \sqrt[5]{\frac{14}{25}}[/tex]
[tex]b = 0.89[/tex]
[tex]a = \frac{25}{0.89^{3.5}} = 37.59[/tex]
Hence, the function is given by:
[tex]y = 37.59(0.89)^x[/tex]
Then, when x = 5.5:
[tex]f(5.5) = 37.59(0.89)^{5.5} = 19.8[/tex]

Make a number line and mark the points that represent the following values of x. 10∙x=0
The point on a number line is the location of the point.
How to draw the number lineThe points are given as:
x = 10 and x = 0
This means that we mark a point at the point 10 on the number line, and another point at the point 0 on the same number line
However, the point 0 would come before point 10 because 0 is less than 10

Choose the correct graph of the function y=-2(2^x)
Answer:
fourth graph in second pic
Step-by-step explanation:
first lets substitute points to see whether the graph increases or decreases
sooo
y = -2(2^0)
y = -2
(0, -2)
y = -2(2^1)
y = -4
(1, -4)
y = -2(2^2)
y = -2(4)
y = -8
(2, -8)
with these points we can tell that the graph is decreasing, since there is two graphs decreasing, we can use the points to see if the parabola lies on the points (i think its called parabola)
its the last graph. fourth graph on page 2

Farmer Bob has a small square garden that is x feet by x feet. What is the area of his garden?
He decides to add 2 feet to one side of the garden and 7 feet to the other side.
What are the lengths of the sides of the new garden?
What is the area of the new garden?
Answer:
The area of the original garden is x^2 square feet.
The lengths of the sides of the new garden are x + 2 feet and x + 7 feet.
The area of the new garden, in square feet, is
[tex](x + 2)(x + 7)[/tex]
[tex] {x}^{2} + 9x + 14[/tex]
1) the area of his garden is, x² feet²
2) the lengths of the sides of the new garden are,
⇒ (x + 2)
⇒ (x + 7)
And, the area of the new garden is,
Area = x² + 9x + 14
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Farmer Bob has a small square garden that is x feet by x feet.
Now,
We know that;
Area of square = Side²
Here, Side = x feet
Hence, the area of his garden is,
Area = x × x
Area = x² feet²
Now, When He decides to add 2 feet to one side of the garden and 7 feet to the other side.
Then, the lengths of the sides of the new garden are,
⇒ (x + 2)
⇒ (x + 7)
Hence, the area of the new garden is,
Area = (x + 2) (x + 7)
Area = x² + 2x + 7x + 14
Area = x² + 9x + 14
Thus, 1) the area of his garden is, x² feet²
2) the lengths of the sides of the new garden are,
⇒ (x + 2)
⇒ (x + 7)
And, the area of the new garden is,
Area = x² + 9x + 14

A group of friends were working on a student film that had a budget of 1200. They spent al their budget on costums and equipment. They used 62% of their budget on equipment. How much money did they spend on costumes?
Answer:
744
Step-by-step explanation:
solved on calcultor
Budget of a film = 1200
Money they spend on equipment :-
= 62% of total expense
= 62% of 1200
[tex]= \frac{62}{100} \times 1200[/tex]
[tex] = \frac{62 \times 1200}{100} [/tex]
[tex] = \frac{74400}{100} [/tex]
[tex]\color{purple}= 744[/tex]
Which means , the group of friends spent 744 on equipment .
Then , money they spent on costume :-
= 100 - 62 % of 1200
= 38% of 1200
[tex] = \frac{38}{100} \times 1200[/tex]
[tex] = \frac{38 \times 1200}{100} [/tex]
[tex] = \frac{45600}{100} [/tex]
[tex] \color{orange} = 456[/tex]
Which means the group of friends spent 456 on costumes .
Therefore , the group of friends spent 456 on costumes .
