Answer:
The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;
= 3 + 4 + 5
= 12 units
a. 12 units = 240 cm
The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.
b. 1 unit = 20 cm
If 12 units are to 240 cm, 1 unit is;
= 240/12
= 20 cm
c. Length of red side;
Red side has length of 5 units. 1 unit is 20 cm.
Length in cm is;
= 5 * 20
= 100 cm

Answer:
(h -f)(x) = x² -x +2(f +h)(x) = x² +x -2(g -f)(x) = x +5(g +h)(x) = x² +2x +3Step-by-step explanation:
Give three functions f(x), g(x), and h(x), you want various combinations of them.
Operations on functionsIf ✧ represents some generic math operator, we often use the notation ...
(f ✧ g)(x)
as a shorthand way to write ...
f(x) ✧ g(x)
The usual meaning of the operator applies.
The three given functions are ...
f(x) = x -2g(x) = 2x +3h(x) = x²(h -f)(x)The definitions are substituted for the function name:
(h -f)(x) = h(x) -f(x) = x² -(x -2)
(h -f)(x) = x² -x +2
(f +h)(x)(f +h)(x) = f(x) +h(x) = (x -2) +x²
(f +h)(x) = x² +x -2
(g -f)(x)(g -f)(x) = g(x) -f(x) = (2x +3) -(x -2) = 2x +3 -x +2
(g -f)(x) = x +5
(g +h)(x)(g +h)(x) = g(x) +h(x) = (2x +3) +x²
(g +h)(x) = x² +2x +3
The perimeter of the triangle shown on the right is 369 feet.
Find the length of each side.
2x
8x-5
Answer:
^two dimentional figure with algebra^
the perimwter from triangle is:
s1 + s2 + s3
ok, enter:
s1 + s2 + s3= 369
x + (8x -5) + 2x = 369
x + 8x - 5 + 2x = 369
group according to the same variable
(x + 8x + 2x) + (-5)=369
11x + (-5)=369
11x - 5= 369
11x = 369 + 5
11x =374
x =374 : 11
x = 34
ok, subtituted:
s1= x
=34 feet
s2= 8x - 5
=8(34) - 5
=272 - 5
=267 feet
s3= 2x
=2(34)
=68 feet

Answer:
A) The correct inequality is: -18 < 53
B) The correct description is: Eduardo sent fewer text messages during May than April
Step-by-step explanation:
Month Number of message
April 53
May -18
A) The correct inequality is: -18 < 53
Reason:
We need to choose the correct inequality, negative number is less than positive number so the inequality will be -18 < 53
B) The correct description is: Eduardo sent fewer text messages during May than April
Reason:
Negative values shows that he has messaged under the allotted limit, while positive values shows the number of messages he was over the limit.

1. Find f(-4) if f(x) = -11x + 7
Answer:
x= 3/11
Step-by-step explanation:
Since you replace f(x) with 4,
4=-11x+7
-3=-11x
-3/-11=x
Answer:
51
Step-by-step explanation:
f(-4); f(x) = -11x + 7
f(x-4) = -11(-4) + 7
f(x-4) = 44 + 7
f(x-4) = 51
I basically just plugged -4 in for the value of the x's, and solved the equation.
i need to solve this questions the sum of two numebers is 5.036 .one number has a 4 in the tenths place and a 7 on the thousandths place.the other number has a 1 in the ones place and and an 2 in the hundredths place. what are the two numbers?
Two numbers, whose sum is 5.036, are 3.407 and 1.629.
Decimals numbers are numbers containing wholes and parts separated by a decimal point ".".
In adding or subtracting decimal numbers, first is to align the decimal point of the decimal numbers. Add/subtract the digits from right to left.
If we have two numbers, one number has a 4 in the tenths place and a 7 on the thousandths place, the second number has a 1 in the ones place and and an 2 in the hundredths place, and their sum is 5.036, we can write that as:
_ . 4 _ 7
+ 1 . _ 2 _
5 . 0 3 6
7 and 9 when added will give a sum of 16.
_ . 4 _ 7
+ 1 . _ 2 9
5 . 0 3 6
Since there is 1 from 16 earlier, 1 and 2 when added will give a sum of 3.
_ . 4 0 7
+ 1 . _ 2 9
5 . 0 3 6
4 and 6, when added will give a sum of 10.
_ . 4 0 7
+ 1 . 6 2 9
5 . 0 3 6
Since there is 1 from 10, 1 added to 1 and 3 will give a sum of 5.
3 . 4 0 7
+ 1 . 6 2 9
5 . 0 3 6
Hence, the two numbers are 3.407 and 1.629.

What is the domain of the function f(x)=-2x + 9 when the range is {-7, 1,9}?
Domain f(x) = 23, 7, -9 for range of { -7, 1, 9}
The domain is f(x) = -2x + 9, and the range of the function is {-7, 1, 9}
To find the domain of the function we have to put the value of x as -7, 1, and 9.
Put x = -7 we have
f(x) = -2x + 9
= -2(-7) + 9
= 14+9
= 23
Now x = 1
f(x) = -2(1) + 9
= -2+9
= 7
Now x = 9
f(x) = -2(9) + 9
= -18 + 9
= -9
Therefore we get the domain of function as 23, 7, -9 for the range {-7, 1, 9}.

Eshaal is creating a model of a pyramid. The model created will need to be scaled up from the blueprint.
If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC?
BC = CE
BC equals AC times CE all over CD
BC equals AC times DE all over CE
BC = AC
Answer:
See attachment
PS:
Can I have Brainliest?
The correct statement is BC equals to AC times CE all over CD.
We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.
Given, DE and AB are parallel
So, [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]
[tex]BC = \frac{AC\times CE}{CD}[/tex]
Therefore in statement form we say that BC equals to AC times CE all over CD.

use the method of undetermined coefficients to set up the 5 × 5 vandermonde system that would determine a fourth-order accurate finite difference approximation to u 00(x) based on 5 equally spaced points,
The fourth-order accurate finite difference approximation is:
u00(x) = c−2u(x − 2h) + c−1u(x − h) + c0u(x) + c1u(x + h) + c2u(x + 2h) + O(h4).
Compute the coefficients using the matlab code fdstencil.m and check that they satisfy the system you determined in part (a).
Test this finite difference formula to approximate u
00(1) for u(x) = sin(2x) with values of h from the array hvals = log space(-1, -4, 13). Make a table of the error vs. h for several values of h and compare against the predicted error from the leading term of the expression printed by fdstencils.
You should observe the predicted accuracy for larger values of h. For smaller values, numerical cancellation in computing the linear combination of u values impacts the accuracy observed.

A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (2, 4) and the stadium in Columbus is at point (7, 6). One unit on the map is 3 miles. The approximate distance between the high school and the stadium to the nearest mile is Answer miles.
Answer:
16 miles
Step-by-step explanation:
Given that :
1 unit = 3 miles
High School = (2, 4)
Stadium = (7, 6)
Approximate distance between high school and stadium :
Distance between High school and Stadium
x1 = 2 ; y1= 4 ; x2 = 7 ; y2 = 6
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Distance = sqrt((7 - 2)^2 + (6 - 4)^2)
Distance = sqrt((5^2 + 2^2))
Distance = sqrt(25 + 4)
Distance =5.3851648 units
1 unit = 3 miles
Approximate Distance in miles :
3 * 5.3851648 = 16.155494
Approximate distance = 16 miles

This is a combinatorics problem.
It is asking us the number of ways a sample of r elements can be obtained from a larger set of n objects where order does not matter and repetitions are not allowed
It is called n choose k and the formula is
[tex]C(n,r) = \binom{n}{r} = \frac{n!}{( r! (n - r)! )}[/tex]
Here the ! symbol represents the factorial of that number
For example,
[tex]n! = n\cdot(n-1)\cdot(n-2)......\cdot3\cdot2\cdot 1[/tex]
Here n = 15 and r = 12
How many ways can we arrange 12 people in 15 slots
[tex]C(n,r) = C(15,12)[/tex]
[tex]= \frac{15!}{( 12! (15 - 12)! )}[/tex]
[tex]= \frac{15!}{12! \times 3! }[/tex]
[tex]= 455[/tex]
You can use a calculator to do this but noting that
15! = 15 x 14 x 13 x 12! and 3! = 3 x 2 = 6 we get
[tex]= \frac{15!}{12! \times 3! } = \frac{15\cdot14\cdot13}{6} = 455[/tex]
