Answer:
x=16 y=38
Step-by-step explanation:
x+y=54.......equation 1
x=y-22........ equation 2
substitute
y-22+y=54
2y-22=54
2y=54+22
2y=76
y=76/2
y=38''
x=y-22
x=38-22
x=16''

Increase £490 by 11% give your answer rounded to 2 DP.
Answer:
£543.90
Step-by-step explanation:
→ Write increase 11% into decimal format
100 + 11 = 111 ÷ 100 = 1.11
→ Multiply the price by the increase in decimal amount
490 × 1.11 = £543.90
A dolphin jumps out of the water with an initial velocity of 20 feet per
second (assume its starting height is O feet). Use the vertical motion
model, h = - 16t2 + vt +8, where v is the initial velocity in feet per
second and s is the height in feet, to calculate the amount of time the
dolphin is in the air before it hits the water again. Round your answer
to the nearest tenth if necessary.
Time in air: seconds
Answer:
1.6 Seconds
Step-by-step explanation:
The equation would be h(t)=-16t^2+20t+8 since 20 is the velocity, and once you input that onto a graph the answer of when it hits the ground is 1.569 seconds, so rounded is 1.6 seconds.

Answer:
A. 6 feet
B. 38 feet of fencing total
Step-by-step explanation:
a. We are given 78 square feet as the total area that the fence encloses. Given this, we can use the A=l*w to solve for the side lengths.
A=l*w
Plug in known variables and simplify...
Step 1: Subtract 78 from both sides.
x^2+7x−78=78−78
x^2+7x−78=0
Step 2: Factor left side of equation.
(x−6)(x+13)=0
Step 3: Set factors equal to 0.
x−6=0 or x+13=0
x=6 or x=−13
For this case we will need to use the positive value.
so to check the answer, we can plug in 6 for x and check if it will equal 78.
(6+7)(6)
13*6
78
b. now given the value of x, we need to solve for the total amount of fencing by finding the perimeter.
We already know that one side is 6+7 or 13, and the other side is 6, so to find perimeter we use the formula 2l+2w
and solve...
2*13+2*6
26+12
38

and it has a minimum
Step-by-step explanation:

Solve the equation
15 - 4x = 2(3x + 1).
[tex]\huge\boxed{\ x=13/10 } :)[/tex]
My steps:
First thing we do is: Rearrange terms
15−4x=2(3x+1)−4x+15=2(3x+1)Second thing we do is: Distribute
−4x+15=2(3+1)−4x+15=6x+2Third thing we do is : Subtract 15 from both sides of the equation
−4x+15=6x+2−4x+15−15=6x+2−15Then you carry on and find solution:
x=13/10

A: 5 + √85 + 2√65
B: 5 + 2√85 + √65
C: √10 + 2√85 + √65
D: 19 + 2√65
The exact perimeter of the quadrilateral ABCD plotted is 5 + √85 + 2√65.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

Does the given matrix, A, have an inverse? If it does, what is A-1?

A
=
2
5
The inverse of the function is [tex]\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]
Inverse of a matrixFor a 2 by 2 matrix, the inverse is generally expressed as:
[tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] ^{-1}=\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right][/tex]
Since the given matrix is a square matrix and 2 by 2, therefore it will have an inverse.
Determine the determinant
|A| = 5(5) - 2(12)
|A| = 25 - 24
|A| = 1
Substitute the values into the formula above
[tex]\left[\begin{array}{ccc}5&12\\2&5\\\end{array}\right] ^{-1}=(1)\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]
Hence the inverse of the function is [tex]\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]

Answer:
The Slope Is 12Step-by-step explanation:
Below are the steps to follow to find the slope of any line.
First you need to pick two points. I chose (2,24) and (4,48). (It does not mater what points you chose.)
Now follow the equation
Slope (m) = ΔY/ΔX
ΔY = 48 – 24 = 24
ΔX = 4 – 2 = 2
24/2 = 12
Then no mater what points you chose, 12 should be your final answer
