Answer:
She has run 259.18m
Step-by-step explanation:
Since Dianne is running around the circular track, she is running around the perimeter of the circle.
Now, we know that the perimeter of a circle is given by;P = 2πr
Thus the perimeter of the track = total distance that the man travels = 2 x π x 55 = 345.575 meters
Now,since she has run 3/4 of the distance, thus, she has run;
(3/4) x 345.575 = 259.18m
8y + -5(-y + 2)
Pls help simplify the expression !!
Answer:
13y-10
Step-by-step explanation:
Expand: -5(-y+2): 5y-10
Add similiar elements: 8y+5y=13y
=13y-10
Answer:
-5 x -y = 5y
-5 x 2 = -10
8y + 5y = 13y
therefore your expression is:
13y - 10

length - 32 cm
What would be the dimensions of the poster at 4 times its current size? (5 points)
O Length - 128 cm, width = 144 cm
O Length - 28 cm, width - 32 cm
O Length = 36 cm, width =
O cm
O Length = 8 cm, width = 9 cm
Answer:
Length=8 cm ,width=9 cm .
Step-by-step explanation:
Given in rectangle
Length of the rectangle=32 cm
Width of the rectangle= 36 cm
According to question
Length of poster= times length of rectangle
Length of poster=
Length of poster=8 cm.
By simplification
Width of poster= times width of rectangle
Width of poster=
Width of poster= 9 cm
By simplification
Hence, Length of poster=8 cm and width of poster=9 cm.
can't quite figure out the limit problem
Use the squeeze theorem; if
1 - x ²/4 ≤ u(x) ≤ 1 + x ²/2,
then taking the limit on each part as x approaches 0 gives
1 ≤ lim [x → 0] u(x) ≤ 1
and so the limit of u(x) as x → 0 is simply 1.

Is s=2/3 a solution of 6s−1=3s?
Answer:
nope
Step-by-step explanation:
No, s=2/3 is not a solution of 6s−1 = 3s.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A linear equation,
6s − 1 = 3s.
Substituting,
s = 2/3,
Equation is,
3 ≠ 2
Simplifying,
6s - 3s = 1
3s = 1
s = 1/3
That means, s = 1/3 is the only solution of the equation.
Therefore, s = 2/3 is not a solution to the equation.

Jake has 3.5 hours before bedtime he must spend 2 hours doing homework the rest of his time will be spent doing puzzles it takes Jake 1/2 hour to complete each puzzle which equation models the number of puzzles P jake can complete before bedtime
3.5 = 2 - (1/2)p
(1/2)p+ 2 = 3.5
3.5 + 2 = (1/2)p
(1/2)p - 2 = 3.5
Answer:
(1/2)p+2=3.5
Step-by-step explanation:
1/2 is hours he spends doing work p would be the variable for how many puzzles he can do plus the 2 hours for homework to equal 3.5 hours in all.
Solve x2 – 2x = 15 by applying the quadratic formula.
Using the quadratic formula, the value of x in the given situation is x = 4 ± √2+60x/2x.
What is the quadratic formula?The quadratic formula in elementary algebra is a formula that yields the answer to a quadratic problem.
In addition to the quadratic formula, other methods of solving quadratic equations include factoring, completing the square, graphing, and others.
A second-order equation of the form ax² + bx + c = 0 denotes a quadratic equation, where a, b, and c are real number coefficients and a 0.
We have:
x² – 2x = 15
x² – 2x - 15 = 0
The formula is:
x = -b ± √b² - 4ac/2a
Now, insert values as follows:
x = -b ± √b² - 4ac/2a
x = -(-2) ± √(-2)² - 4(x)(-15)/2x
x = 4 ± √2+60x/2x
Therefore, using the quadratic formula, the value of x in the given situation is x = 4 ± √2+60x/2x.

Answer:
(0, 1) and (4, 7)
Step-by-step explanation:
We are going to find the equation that satisfy the question.
The equation of a line is: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
The problem gives us the slope and a point the line passes through.
In order to find b, we plug in the given point (2,4) and solve.
[tex]4=\frac{3}{2} *2+b[/tex]
[tex]4=3+b\\1=b\\[/tex]
The equation for the line is:
[tex]y=\frac{3}{2} x+1[/tex]
By plugging in the points to see if it is true, we get that only (0,1) and (4,7) are on the line.
Eliminate the parameter. x = t^2 + 1, y = t^2 - 1.
Answer:
Eliminating the parameter, the equation is [tex]y = x - 2[/tex]
Step-by-step explanation:
We are given the following parametric equations:
[tex]x = t^2 + 1[/tex]
[tex]y = t^2 - 1[/tex]
We want to eliminate the parameter t. From the first equation:
[tex]x = t^2 + 1[/tex]
[tex]t^2 = x - 1[/tex]
Replacing in the second equation:
[tex]y = x - 1 - 1[/tex]
[tex]y = x - 2[/tex]
Eliminating the parameter, the equation is [tex]y = x - 2[/tex]
