Answer:
ω= 0.01 rad/s
Step-by-step explanation:
The given data is question is ,
r = 100ft .t = 3 min = 180s.Firstly let's find the linear speed. Which is
=> v = Circumference/time
=> v = 2πr/180s
=> v = 3.14 × 100ft ./ 90
=> v = 3.48 ft/s ≈ 1m/s
Now the angular speed and linear speed are related as follows ,=> v = r[tex]\omega[/tex]
=> [tex]\omega[/tex] = v/r
=> [tex]\omega[/tex] = 1/100
=> [tex]\omega[/tex] = 0.01 rad/s
Hence the angular speed is 0.01 rad/s.Last exam question for the day And im finally off!

than girls, work out how many girls
there are
Answer:
48+x/x=7/1
48+x=7x
6x=48
x=8
no. of girls = 8
no.of boys= 48+8
= 56
The answer is 8
Answer:
8 girls
Step-by-step explanation:
Ratio boys to girls = 7:1
There area 48 more boys than girls
First lets make an equation
7x - 1x = 48
6x = 48
x = 8
There are 8 girls
Check:
7*x : 1*x =
56 : 8

Please help me! What is x and y? Thank you!
Answer:
x=3. y=6
Step-by-step explanation:
So, to solve x and y, we need to take the equivelent sides of the two triangles, take their equations, and solve them.
So to find what x equals, we can take the 13, and make it equal to the 4x+1:
13=4x+1
Subtract the one from both sides:
12=4x
Divide both sides by 4:
3=x
Or
x=3
So we know the x value is 3.
Now lets solve for y using the bottom equations:
2x+y=8x-2y
Subtract 1y from both sides:
2x=8x-3y
Subtract 8x from both sides:
-6x=-3y
Divide both sides by -6:
x=1/2y
So we already know that x=3, lets plug that in for x, and solve for y:
3=1/2y
Or
1/2y=3
Multiply both sides by 2 to get 1y:
y=6
So we know that y is equal to 6.
Hope this helps!
The identity (x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2 can be used to generate Pythagorean triples. What Pythagorean triple could be generated using x = 8 and y = 3?
Answer:
The triple are: 48, 55 and 73
Step-by-step explanation:
Given
[tex](x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2[/tex]
[tex]x = 8; y=3[/tex]
Required
The Pythagorean triple
We have:
[tex](x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2[/tex]
Substitute: [tex]x = 8; y=3[/tex]
[tex](8^2 + 3^2)^2 = (8^2 - 3^2)^2 + (2*8*3)^2[/tex]
[tex](64 + 9)^2 = (64 - 9)^2 + (48)^2[/tex]
[tex](73)^2 = (55)^2 + (48)^2[/tex]
[tex]5329 = 5329[/tex]
Hence, the triple are: 48, 55 and 73
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=26°, and DB = 48 feet. Find the length of BC to the nearest tenth of a foot.
The length of BC Is ___ ft.
Answer:
98.4 feets
Step-by-step explanation:
To obtain BC
we could make use of B as angle, the apply the trigonometric relation :
Tan B =adjacent / hypotenus
Tan B = DB / BC
Tan 26 = 48 / BC
0.4877325 = 48 / BC
BC = 48 / 0.4877325
BC = 98.4 feets

Which of the following notations correctly describe the end behavior of the polynomial graphed below?
Answer:
Step-by-step explanation:
B. As x approaches negative infinity, f(x) appoaches positive infinity.
As x approaches positive infinity, f(x) approaches negative infinity.
For the given polynomial the end behaviour are -∞ and ∞. The correct option is (B).
How to find the end behaviour for a polynomial?A polynomial is defined as the algebraic expression having all the powers to its terms as whole number. In order to find the end behaviour of a polynomial p(x), determine its value for two cases when x approaches to infinity and minus infinity.
From the graph of the polynomial given in the problem it can be observed as,
As the value of x approaches ∞ , f(x) becomes -∞.
And, as the value of x approaches -∞ , f(x) becomes ∞.
Hence, the end behaviour are given as -∞ and ∞.

If 335 of these cars were parked with their bumpers touching, they would be almost exactly a mile long.
If your question refers to traffic jams, the answer will be a bit different, since cars in traffic jams don’t get that close together. I’m going to take a wild guess here, but let’s assume that there is a 4-foot gap between cars in our hypothetical traffic jam. now put that in to 13 miles

A square has an area of 49in^2. If the same amount is added to the length and removed from the width, the resulting rectangle has an area of 45in^2. Find the dimensions of the rectangle Round your answer to the nearest tenth, when appropriate
The area of a rectangle is given as:
Area = Length x width
The dimensions of the rectangle are 9 inches and 5 inches.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Area of a square = 49 in²
Area of a square = side²
This means the side of the square is 7 inches.
Now,
Let the same amount be x.
The area of the rectangle = 45 in²
The length of the rectangle = 7 + x
The width of the rectangle = 7 - x
The area of the rectangle = Length x Width
45 in² = (7 + x)(7 - x)
45 = 49 - 7x + 7x - x²
45 = 49 - x²
x² = 49 - 45
x² = 4
x = 2
Now,
The dimensions of the rectangle are:
Length = 7 + x = 7 + 2 = 9 inches
Width = 7 - x = 7 - 2 = 5 inches
Thus,
The dimensions of the rectangle are 9 inches and 5 inches.
