Answer:
YW = 6
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 8^2 = 10^2
x^2 + 64 = 100
x^2 + 64 - 64 = 100 - 64
x^2 = 36
√x^2 = √36
x = 6
Line YW is equal 6 feet
Step-by-step explanation:
I used the pythagorean theorem
1. 8 squared plus b squared equals 10 squared
2. 64 plus b squared equals 100
3. 100 - 64 equals 36
4. B squared equals 36
5. square root both sides
6. b equals 6 feet
14.4 A Book and a Cake A book costs $45. Sales tax on the book is 7%. Write two different expressions that represent the final cost of the book in dollars. Pne of the expressions should use only a single multiplication and no other operations.
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars
(0.85). 32 represents the final price of the cake in dollars because...
Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.
Step-by-step explanation:
1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.
2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.
The graph of a linear system is shown. What is the solution to this linear system? Enter a value in each box to create an ordered pair.
Answer:
(1,2)
Step-by-step explanation:
The solution would be where both lines intersect.
In this case, the intersected point is (1,2)
Suppose an object is launched from ground level directly upward at 57.4 f/s Write a function to represent the object’s height over time.
Answer: p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t
Step-by-step explanation:
We can suppose that the only force acting on the object is the gravitational force, then the acceleration of the object will be equal to the gravitational acceleration.
Then we can write:
a(t) = -32 ft/s^2
Where the negative sign is because this acceleration is downwards.
Now, to get the vertical velocity of the object, we need to integrate over time to get:
v(t) = (-32 ft/s^2)*t + v0
where t represents time in seconds and v0 is the constant of integration, and in this case, is the initial vertical velocity.
In this case, the initial velocity is 57.4 ft/s upwards, then the velocity equation is:
v(t) = (-32 ft/s^2)*t + 57.4 ft/s
To get the position equation we need to integrate over time again, to get:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t + p0
Where p0 is the initial height of the object, as it was launched from the ground, then the initial position is p0 = 0ft.
then the position equation (that is the function that represents the height of the object as a function over time) is:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t
p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t

What is the answer to this equation? 3y-6/9=4-2y/-3? Pls help I need it for tomorrow I’ll give brainiest!
Answer:
11y+10/3 if you're looking to simplify. hope this helps!!
Answer:
y=2
Step-by-step explanation:
multiply each side by 27 to get rid of the denominator
3(3y-6)= -9(4-2y) is what is left
solve
9y-18=-36+18y
9y=18
y=2
You can also plug in 2 to the equation to check.

-8 = n/7 can someone solve this w work pleath
Answer: n = -56
Step-by-step explanation:
first, we multiply both sides by 7, un order to get the variable by itself. this is the important step.
-56 = n
then, we just simply swap the sides in order to get the variable on the left. (not necessary, just looks like a proper equation that way.)
n = -56
work:
-8 = n/7
x7 x7
-56 = n
n = -56
Simplify: 6(5x - 2) - (3x - 4)

y = 4x + 1
y = 2x^2+ 7x - 1
Answer:
[tex]Given,\\y = 4x+1......(1)\\y = 2x^2+7x-1.............(2)\\Equating~equation (1)~and~(2),\\4x+1 = 2x^{2} +7x-1\\or, 2x^{2}+7x-4x-1-1=0\\or, 2x^{2} + 3x-2=0\\or, 2x^{2} +4x-x-2=0\\or, 2x(x+2)-1(x+2)=0\\or, (x+2)(2x-1)=0\\i.e. x=-2 ~or~ \frac{1}{2} \\When~x=2,~equation(1)~becomes ~y=4(-2) +1=-7\\When~x=-\frac{1}{2},~equation (1)~becomes~y=4(\frac{1}{2}) +1 = 2+1=3[/tex]
So, the required values of x are -2 and 1/2 and that of y are -7 and 3.
