What is the domain of F
Answer:
-5 ≤x≤6
[-5,6]
Step-by-step explanation:
The domain is the values that the input takes
x goes from -5 (inclusive) to 6 (inclusive)
-5 ≤x≤6
[-5,6]
Answer:
[-5, 6]
Step-by-step explanation:
The domain of a function is the list of x values. Since the endpoints are shaded, that means those x values are included as well. Therefore, the domain of f is [-5, 6].

Find the slope of a line parallel to the line whose equation is y-4=7(x+2).
Answer:
m'=7
Step-by-step explanation:
they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:
m = m'
y-4=7x+14
y=7x+18
y=mx+h
So m = 7
& m' = 7

Answer:
a = 3x
b = -6x^2
c = 4
Step-by-step explanation:
to find b we have to multiply (x - 3) with 2x^2
= 2x^3 - 6x^2
b = - 6x^2
to find a
in the second step of division to get -9x
we have to multiply x - 3 with 3x
a = 3x
to find c we have to add next term after x in the first equation that is 4
in equation 8x + 4
so c = 4

City planners are planning to build a new community pool. They agree that the pool will be rectangular in shape, but the proposed dimensions changed. At the most recent meeting, it was determined that the width would remain at 12.3 meters but that the length would increase by 4.3 meters. So, the pool would now cover an area of 213.65 square meters. Which equation can be used to determine the original length of the pool, I?
A. 213.65 = 4.3(1+ 12.3)
B. 213.65(I+16.6)
C. 213.65 = 12.3(I+ 4.3)
Answer:
C. 213.65 = 12.3(I+ 4.3)
Step-by-step explanation:
Original length: l
New length: l + 4.3
area: LW
area: 213.65 m²
area = LW = (l + 4.3)(12.3)
(l + 4.3)(12.3) = 213.65
12.3(l + 4.3) = 213.65
Answer: C. 213.65 = 12.3(I+ 4.3)

Answer:
4 : 1
Step-by-step explanation:
Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:
2² : 1² = 4 : 1 . . . . . . ratio of triangle areas
find the area of the triangles with the following base and heights:
a) base 10m and height 6m. b) base 25 cm and height 14 cm.
Answer:
triangle 1. 10•6=60m²
triangle 2. 25•14= 350cm²
* in case u need help, to find the area of a triangle use this formula;
b • h = a
base • height = area

If the ant were to walk straight down the side of the tower until it reached the ground, how far would the ant travel? Which trigonometric ratio would you use to find this distance? Use the ratio to find the measurement. (4 points: 1 point for the method, 2 points for shown work, 1 point for the answer)
6. Confirm that your answer to question 5 is correct using the Pythagorean Theorem instead of trig ratios. (3 points)
Answer:
The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.
Step-by-step explanation:
You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x
=> x = 50 m / tan(86°)
x = 50 m / 14.30 = 0.98 m

A particle moves along the x-axis so that time t>0 the position is given by x(t)=0.5t^4 - 1.5t^3 - 2t^2 + 6t - 1. What is the velocity of the particle at the first instance the particle is at the origin?
The velocity of the particle at the first instance it is at the origin (approximately t ≈ 2.944) is approximately 16.885 units per time unit.
To find the velocity of the particle at the first instance it is at the origin, we need to find the value of t when x(t) = 0.
Since the particle is at the origin when x(t) = 0, we have:
[tex]0.5t^4 - 1.5t^3 - 2t^2 + 6t - 1 = 0[/tex]
Using numerical methods or graphing the equation, we find that the roots are approximately t ≈ -0.618, t ≈ 1.532, t ≈ 3.143, and t ≈ 2.944.
Since t > 0, the first instance the particle is at the origin corresponds to t ≈ 2.944 (the smallest positive real root).
Now, to find the velocity of the particle at this instance, we need to find the derivative of the position function x(t) with respect to time t, which gives us the velocity function v(t):
v(t) = dx/dt
[tex]v(t) = d/dt (0.5t^4 - 1.5t^3 - 2t^2 + 6t - 1)\\v(t) = 2t^3 - 4.5t^2 - 4t + 6[/tex]
Now, we can find the velocity at t ≈ 2.944:
[tex]v(t = 2.944) = 2(2.944)^3 - 4.5(2.944)^2 - 4(2.944) + 6[/tex]
v(t ≈ 2.944) ≈ 16.885
So, the velocity of the particle at the first instance it is at the origin (approximately t ≈ 2.944) is approximately 16.885 units per time unit.
