Answer:
48cm
Step-by-step explanation:
96/12=8
This means that 8 is the factor by which the diagram and the actual ramp vary
so then you multiply 8 times the height on the diagram to find the true height
8x6=48

Guys, I really need that help T-T.
The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?
Answers
Legs: 5, √3. Hypotenuse: √28
So your legs are: a and b, and ur hypotenuse is c
a^2+b^2=c^2
Which means
5^2+√3 has to equal to √28^2.
Let’s solve it
5^2+√3^2= √28^2
= 25+3=28
28=28
So that is a right triangle.
First to Answer:
The triangle would be a cute Scalene Triangle!
Here's all that you really can do with solving that
√28 =5.29150262213
√8 = 2.82842712475
Side a = 2.8
Side b = 5
Side c = 5.2

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.
Answers
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

A regular polygon has 12 sides find the size of each of its interior angles
Answers
Answer:
150°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° ( n - 2) ← n is the number of sides
Here n = 12, then
sum = 180° × 10 = 1800°
Since there are 12 interior angles, then
size of each interior angle = 1800° ÷ 12 = 150°

For all values of x, f(x) = x^2 + 1 and g(x) = x-5
(a) Show that fg(x) = x^2 - 10x + 26
(b) Solve fg(x) = gf(x)
Answers
Answer:
a) f g(x) = x³ - 5 x² + x -5
b) g(f(x) = x³ - 5 x² + x -5
Step-by-step explanation:
Step(i):-
Given that f(x) = x² + 1 and g(x) = x-5
a)
f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26
Step(ii):-
a) f g(x) = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5
b) g(f(x) = g(x) f(x) = (x-5) (x²+1) = x³ - 5 x² + x -5

Step-by-step explanation:
If you multiply the x value of 10, substitute it into the equation. Using the equation y=4/5x, you will get the y value of 8.
When you substitute the x value of 5 into the equation. You will get 4.
You do this for the rest of the x values and will get the correct y values.
