PLEASE HELP FAST MAKE SURE YOU READ IT CORRECT I WILL GOVE BRAINLIST AND EXTRA POINTS PLEASE HELP!
Answer:
f(5) = 3
Step-by-step explanation:
f(x) is the y coordinate at x.
At x = 5, y = 3, so f(5) = 3.
Samuel scored a 32.5/40 on his most recent math test what percent did he earn in the test round to the nearest whole percent
Answer: 81%
Step-by-step explanation:
From the question, we are informed that Samuel scored a 32.5/40 on his most recent math test.
Based on the values given, to convert it to percentage, we have to multiply the score by 100. This will be:
= 32.5/40 × 100
= 3250/40
= 81.25%
= 81% to nearest whole number
33.For a car traveling at a constant speed, the distance driven, d
kilometers, is represented by d(t)=80t, where t is the time in hours. The
cost of gasoline, in dollars, for the drive is represented by C(d)=0.09d.
Evaluate C(d(10))
Given:
[tex]d(t)=80t[/tex]
[tex]C(d)=0.09d[/tex]
To find:
The value of [tex]C(d(10))[/tex].
Solution:
We have,
[tex]C(d(10))=C(80(10))[/tex] [tex][\because d(t)=80t][/tex]
[tex]C(d(10))=C(800)[/tex]
Now,
[tex]C(d(10))=0.09(800)[/tex] [tex][\because C(d)=0.09d][/tex]
[tex]C(d(10))=72[/tex]
Therefore, the value of [tex]C(d(10))[/tex] is 72.

y(t) = distance of weight from equilibrium position
ω= angular frequency (measured in radians per second)
A = amplitude
Ø= phase (depends on initial conditions)
c1 = A sin
c2 = A cos
Prove that: Asin(ωt+Ø)=c2sinωt+c1cosωt
Note: c1 and c2 are actually with the number slightly below the letter, if that makes sense. It wouldn't let me type it that way. Anyway, if anyone can help I would really appreciate it! Thank you!
Answer:
An object moving along the x-axis is said to exhibit simple harmonic motion if its position as a function of time varies as
x(t) = x0 + A cos(ωt + φ).
The object oscillates about the equilibrium position x0. If we choose the origin of our coordinate system such that x0 = 0, then the displacement x from the equilibrium position as a function of time is given by
x(t) = A cos(ωt + φ).
A is the amplitude of the oscillation, i.e. the maximum displacement of the object from equilibrium, either in the positive or negative x-direction. Simple harmonic motion is repetitive. The period T is the time it takes the object to complete one oscillation and return to the starting position. The angular frequency ω is given by ω = 2π/T. The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
The velocity of the object as a function of time is given by
v(t) = dx(t)/dt = -ω A sin(ωt + φ),
and the acceleration is given by
a(t) = dv(t)/dt = -ω2A cos(ωt + φ) = -ω2x.

Zach created a blueprint using only similar parallelograms. Which statement about the parallelograms must be true? A) The parallelograms all have congruent sides and angles. B) The parallelograms have corresponding angles that are not congruent. C) The parallelograms have proportional corresponding sides. D) The parallelograms have corresponding sides that are congruent.
Answer:
A) The parallelograms all have congruent sides and angles.
Step-by-step explanation:
Remember, a parallelogram in simple words is a flat shape (either a square, rectangle, or rhombus) that has four sides of equal length, and whose opposite angles are congruent.
In other words, Zach's blueprint using similar parallelograms would be chosen from either a square, a rectangle, or a rhombus, which all have congruent sides and angles.

C

what is the volume of a regular octahedron inside a cube with the length of its sides measuring 4 centimeters
Answer:
We conclude that the volume of a regular octahedron will be:
[tex]\:\:V\:\approx \:30.17[/tex] cmStep-by-step explanation:
Given
The length of one of the side or edge of a regular octahedron = a = 4 cm
To determine
The volume of a regular octahedron = V
Using the formula to determine the volume of a regular octahedron
[tex]V\:=\:\frac{\sqrt{2}}{3}a^3[/tex]
substituting a = 4 in the volume equation
[tex]V=\frac{\sqrt{2}\cdot \:4^3}{3}[/tex]
[tex]V=\frac{64\sqrt{2}}{3}[/tex] ∵ 4³ = 64
[tex]\:\:V\:\approx \:30.17[/tex] cm
Therefore, we conclude that the volume of a regular octahedron will be:
[tex]\:\:V\:\approx \:30.17[/tex] cmhelp me l,ll give you brainest

Solve the equation for y
- 5x + 2y = 1
Answer:
14x+37=4x
Step-by-step explanation:
Evaluate f(x)=x-5 when x=-5,x=0,and x=5
Answer:
f(x) = x - 5
f(-5) = -5 - 5
= -10
f(0) = 0 - 5
= -5
f(5) = 5 - 5
= 5

Answer:
7.5
Step-by-step explanation:
7.5 is the smallest. 7.51 is bigger by 0.01, 7.501 is bigger by 0.001 and 7.5 with a dot on top means that the number 5 repeats itself indefinately after the comma so it is like if we wrote 7.55555555 and the 5 kept going on forever

A Family spent a total of $73.75 on movie tickets and snacks. Each ticket cost $12.50, and each snack cost $4.75. If the family bought a total of 9 tickets and snacks, How many of each did they buy?
Answer:
4 Tickets and 5 Snacks
Step-by-step explanation:
Answer:
The family bought 4 tickets and 5 snacks.
Step-by-step explanation:
$12.50 x 4 tickets = 50
$4.75 x 5 snacks = 23.75
$50 + $23.75 = $73.75

(19) Calculate $ 328.67 as a percentage of $ 150
O
219%
O
209%
199%
189%
Answer:
219%
Step-by-step explanation:
Answer:
219%
Step-by-step explanation:
Since $300 is double the price of $150, it is safe to say that it is over 200% which comes down to the first two answers 209% and 219%. Divide $328.67 by $150 to get to the number which is around 2.19113333, multiply by 100 to get the answer.
Which step contains an error?
O step 2
O step 4
O step 6
O step 8

Write an equation in slope-intercept form for the line parallel to y=3x-2 that passes through the point (5,-2)
Answer:
y = 3x - 17
Step-by-step explanation:
Parallel lines have the same slope.
The slope of the given line, y = 3x - 2 is 3.
The equation we are looking for is of the form
y = mx + b
Since we know the slope, m, is 3, we have
y = 3x + b
To find the value of b, we substitute x and y with the values from the given point and solve for b.
-2 = 3(5) + b
b = -17
The equation is
y = 3x - 17
