Answer:
[tex]5 + 7x \le 33[/tex]
Step-by-step explanation:
Given
[tex]Base\ Charge = 5[/tex]
[tex]Additional = 7[/tex] per mile
[tex]Total = 33[/tex]
Required
Determine the inequality
First, we need to determine the total cost for x miles.
[tex]Cost = Base\ Charge + Additional * x[/tex]
[tex]Cost = 5 + 7 * x[/tex]
[tex]Cost = 5 + 7x[/tex]
The total cost can not exceed the amount he has, so the inequality is:
[tex]Cost \le Total[/tex]
[tex]5 + 7x \le 33[/tex]
What effect does armature reaction have on the torque speed characteristic of a DC shunt motor?
Answer:
Step-by-step explanation:
The armature reaction in the motor affects the torque speed characteristics of the motor. Due to the armature reaction in the motor the shape of the torque speed characteristics will changes. The relation between torque and speed of the motor is given below.
…… (1)
where
Terminal voltage of the motor
Flux in the motor
Torque induced in the motor
Armature resistance
If a motor has armature reaction, as the load increases the flux weakening effect reduces the flux in the field winding. From equation (1), as the flux reduces, the speed of the motor increases at a given load over the speed it would run at without armature reaction.
There are 192 cubes. The length is 6 and the width is 4. What is the height?
Answer:
Height = 8
Step-by-step explanation:
Volume = Length x width x height
192 = 6 x 4 x H
192 = 24 x H
192/24 = H
8 = H
Height = 8
Write f(x) in terms of sin(x) and cos(x).
Answer:
f(x) = cos(x)
Step-by-step explanation:
Given the expression
[tex]tan(x)csc(c) = \frac{1}{f(x)}[/tex]
Recall that;
[tex]tan(x) = \frac{sin(x)}{cos(x)} \\csc(x) = \frac{1}{sin(x)} \\[/tex]
Substitute into the given expression
[tex]tan(x)csc(c) = \frac{1}{f(x)}\\\frac{sin(x)}{cos(x)} \frac{1}{sin(x)} = \frac{1}{f(x)}\\\frac{1}{cos(x)} = \frac{1}{f(x)}[/tex]
Cross multiply
[tex]cos(x) = f(x)\\Swap\\f(x) = cos(x)[/tex]

express y as a function of x.
I keep getting hairy answers and I'm not sure I'm doing this correctly
Answer:
[tex]y = 7x - \frac{2}{6}[/tex]
Step-by-step explanation:
In y = (1)/(2) (3x+4) - (1)/(3) (x+7)
y = 7x-2/6 (Solving for y)
x = 6y/7 + 2/7
Answer:
4 ln y = 1/2 ln (3x + 4) - 1/3 ln (x + 7) + ln C4 ln y = ln [C*(3x + 4)[tex]^{1/2}[/tex]/(x + 7)[tex]^{1/3}[/tex]]ln y = 1/4 ln [C*(3x + 4)[tex]^{1/2}[/tex] / (x + 7)[tex]^{1/3}[/tex]]ln y = ln [C[tex]^{1/4}[/tex](3x + 4)[tex]^{1/8}[/tex] / (x + 7)[tex]^{1/12}[/tex]]y = C[tex]^{1/4}[/tex](3x + 4)[tex]^{1/8}[/tex] / (x + 7)[tex]^{1/12}[/tex]or
y = [tex]\sqrt[24]{C^6(3x + 4)^3/(x + 7)^2}[/tex]What is the range of this function?
{(-2,3), (0,1), (1, -2), (2,5)}
Answer:
3,1,-2,5
Step-by-step explanation:
The range means the y number of the domain (x)
Answer:
Hi! The answer to your question is {3,1,-2,5)

Answer:
9. B. 32 millimeters
10. C. 7 inches
11. C. 56.24 millimeters
13. B. 14.13 square feet
Step-by-step explanation:
9. Radius of a circle or any circular shape = ½ of its diameter
Diameter of the disk = 64 millimeters
Radius of the disk = ½(64) = 32 millimeters
10. Width of the cooler = 6 in.
Length = 8 in.
Volume = 336 in.³
Height = ?
Formula for volume of a rectangular prism = L*W*H
Plug in the values
336 = 8*6*H
336 = 48*H
Divide both sides by 48
336/48 = H
H = 7 inches
11. A dime has a circular shape
The circumference of the dime = circumference of a circle = πd
Where,
d = 17.91 millimeters
π = 3.14
Plug in the values
C = 3.14 × 17.91 = 56.2374
≈ 56.24 millimeters (nearest hundredth)
12. Area of the top of the desk = area of semicircle = ½ × πr²
Where,
r = ½(6) = 3 ft
π = 3.14
Plug in the values
Area = ½ × 3.14 × 3² = ½ × 3.14 × 9
Area = 14.13 square feet

How do you convert a fraction or decimal to a percent?
Answer:
a
Step-by-step explanation:
Answer:
To convert a decimal to a percent, multiply it by 100 (move the decimal place two digits to the right) and add the "%" sign.
A fraction must be converted into a decimal first by dividing the denominator into the numerator, then converting that answer to a percent like above.

Find each angle measure
Answer:
angle 1 = 63°
angle 2 = 117°
angle 3 = 63°
Step-by-step explanation:
angle 2 = 117° (vert.opp.angles)
angle 1 = angle 3 (vert.opp.angles)
angle 1 + angle 2 + angle 3 + 117° = 360°
angle 1 + 117° + angle 3 + 117° = 360°
angle 1 + angle 3 = 360° - 117° - 117°
angle 1 + angle 3 = 126°
angle 1 = 63°
angle 3 = 63°

HELP PLEASE THIS IS DUE IN 15 MIN!!!!!!!!!!!
look at the picture
Answer:
c reflexive property
if you look at it it's reflecting
=============================================================
Explanation:
For statement 1, we'll have angle O congruent to angle M. This is visually given by the angle arcs that are the same.
For statement 2, we'll have segment OL congruent to segment LM. This is also given because of the tickmarks on the segments to show they are the same length.
In statement 3, angle KLO is congruent to angle MLN. The reason for this is they are vertical angles. So if your teacher was asking about what goes for reason 3, then you would be correct in selecting choice A.
The actual answer is choice B) ASA because we have two pairs of congruent angles (refer to statements 1 and 3 mentioned earlier); between those angles for each triangle we have a pair of congruent segments (refer to statement 2). So that's why we go for ASA. As you can probably guess, "A" stands for "angle" and "S" stands for "side". The order matters. The side must be between the angles in question. This means AAS is slightly different than ASA.
Side note: The reflexive property is the idea that any segment or angle is congruent to itself. It's not used at all here, but it's useful in other situations.
Another side note: CPCTC stands for "corresponding parts of congruent triangles are congruent". It basically means that if two triangles are congruent, then the pieces that match up together are congruent as well.

a bag contains 1 red beads,2 yellow beads,2 green beads and 1 blue beads
a bead is chosen at random
a)what is probability that it is green ?
b)what probability that it is green or yellow
Answer:
a) 2/6 b) 4/6
Step-by-step explanation:
You add the amount of beads: 1+2+2+1= 6
And take the amount of green beads and put it over the total amount so 2/6
For b you do the same but add the green and yellow beads and put that over the total amount 4/6
Answer:
Step-by-step explanation:
a) 2/6 = 1/3
b) green or yellow = (2/6 x 1/5) + (2/6 x 1/5) = 1/15 x 1/15 = 1/225

Write the equation of the line that passes through the point (-1,-5) and has a slope of -2?
Answer: -7 is the answer.
Step-by-step explanation:
y2 - y1 = m (x2 - x1)
y - (-5) = -2 {x - (-1)} [Taking y2 as y and x2 as x]
y + 5 = -2 (x + 1)
y + 5 = -2x -2
y + 2x = -2 - 5
2x + y = -7
