Answer:
y = 2x + 4
Step-by-step explanation:
So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.

2(z - 10) = -4
Answer:
z=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(z−10)=−4
(2)(z)+(2)(−10)=−4(Distribute)
2z+−20=−4
2z−20=−4
Step 2: Add 20 to both sides.
2z−20+20=−4+20
2z=16
Step 3: Divide both sides by 2.
2z2=162
z=8

The following are the ages (years) of 5 people in a room: 22, 13, 17, 15, 17 A person enters the room. The mean age of the 6 people is now 17. What is the age of the person who entered the room?
Answer:
the 6th man's age is 58!
Step-by-step explanation:
First you have to find the mean of 22, 13, 17, 16, and 17, by first adding 22, 13, 17, 16, and 17 to get 85. Because mean is the numbers added up divided by the total amount of numbers, there are 5 numbers and then you have to divided 85 by 5.
After you get the mean of these numbers, find the other number which will level the mean to 17.

Step-by-step explanation:

AB = AC.... (given)
\therefore m\angle ABC = m\angle ACB\\[/tex] (Property of isosceles triangle)
[tex] \because m\angle ACB = 47\degree \\
\therefore m\angle ABC = 47\degree \\
2y\degree + 47\degree+47\degree = 180\degree \\
2y\degree + 94\degree= 180\degree \\
2y\degree = 180\degree - 94\degree \\
2y\degree = 86\degree \\\\
y = \frac{86\degree}{2} \\\\
y\degree = 43\degree \\\\

n = 365
x = 12
Step 2: Solve for A
Substitute: A = 230(1 + 0.063/365)³⁶⁵⁽¹²⁾Divide: A = 230(1 + 0.000173)³⁶⁵⁽¹²⁾Multiply: A = 230(1 + 0.000173)⁴³⁸⁰Add: A = 230(1.00017)⁴³⁸⁰Exponents: A = 230(2.1296)Multiply: A = 489.808Find the instantaneous rate of change of the function f(x)=3x^2 as x approaches 3.
Answer:
The instantaneous rate of change as x approaches 3 is 18.
Step-by-step explanation:
From Differential Calculus and Geometry we remember that instantaneous rate of change of the function is represented by a tangent line, whose slope is determined by the first derivative of the curve. Let [tex]f(x) = 3\cdot x^{2}[/tex], the instantaneous rate of change of the function when x approaches 3 is deducted from the definition of derivative:
[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex] (1)
[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]
[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x^{2}+2\cdot x\cdot h +h^{2})-3\cdot x^{2}}{h}[/tex]
[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot x^{2}+6\cdot x\cdot h+3\cdot h^{2}-3\cdot x^{2}}{h}[/tex]
[tex]f'(x) = \lim_{h\to 0} \frac{6\cdot x\cdot h +3\cdot h^{2}}{h}[/tex]
[tex]f'(x) = \lim _{h\to 0} (6\cdot x+3\cdot h)[/tex]
[tex]f'(x) = 6\cdot x \cdot \lim_{h\to 0} 1 + 3\cdot \lim_{h\to 0} h[/tex]
[tex]f'(x) = 6\cdot x[/tex] (2)
If we know that [tex]x = 3[/tex], then the instantaneous rate of change as x approaches 3 is:
[tex]f'(3) = 6\cdot (3)[/tex]
[tex]f'(3) = 18[/tex]
The instantaneous rate of change as x approaches 3 is 18.

Dave ran from one corner of a field to the opposite corner , a distance of 100 meters . Then he ran along its length, a distance of 96 meters . How wide is the field
Answer:
28 meters wide
Step-by-step explanation:
This involves using the Pythagorean Theorem.
We know: a (the length)=96, b (the width)=?, c (diagonal distance)=100
a^2+b^2=c^2
96^2+b^2=100^2
9216+b^2=10000
b^2=784
b=28
The field is 28 meters wide

14
15
16
Answer:
14 integers
Step-by-step explanation:
Given
[tex]Range: -6.01\ to\ 7.75[/tex]
Required
Determine the number of integers
Integers implies numbers without decimals; it could be positive or negative or 0.
So, within the range: the integers are:
[tex]-6, -5, -4,-3,-2,-1,0,1,2,3,4,5,6,7[/tex]
Notice that the above numbers are integers within the given range.
By counting them, we get the required number of integers.
[tex]Numbers = 14[/tex]
Hence, there are 14 integers
At the grocery store, sliced turkey deli meat is on sale for $11 for 2 pounds. a. What is the cost per pound of sliced turkey deli meat? b. Write an equation to represent the cost "y" of sliced turkey deli meat measured in "x" pounds. *
Answer:
- $5.5 per pound
- [tex]y = 5.5x[/tex]
Step-by-step explanation:
Given
$11 for 2 pounds
Solving (a): Cost per pound
This is calculated by dividing $11 by 2 pounds
[tex]Cost\ per\ pound = \frac{\$11}{2\ lb}[/tex]
[tex]Cost\ per\ pound = \$5.5/\ lb[/tex]
Hence, the cost per pound is $5.5 per pound
Solving (b): Represent as an equation.
If 1 pound costs $5.5 (as shown in (a))
Then
x pounds costs $5.5 * x
[tex]Cost = 5.5 * x[/tex]
[tex]Cost = 5.5x[/tex]
This cost is represented with y
[tex]y = 5.5x[/tex]

Answer:

Step-by-step explanation:
The segment AC is the angle bisector of angle BAD and angle BCD.
What is an angle bisector?A ray, segment, or line that divides a given angle into two equal angles is known as an angle bisector.
When something is bisected or bisected, it is split into two equal sections. In geometry, an angle bisector is a line or ray that divides a triangle into two equal angles.
here, we have,
Given that ΔABC ≅ ΔADC Prove: AC bisects ∠BAD and AC bisects ∠BCD
From the given data it is concluded that all the corresponding angles of the triangle are equal to each other.
In the triangle ABC and ADC:-
∠BAC = ∠DAC
∠BCA = ∠DCA
From the above proof, it is concluded that the AC bisects ∠BAD and ∠BCD.
Therefore, the segment AC is the angle bisector of angle BAD and angle BCD.

cos 76, sin 14
The pair of trigonometric functions that are equivalent is cos76°, sin14°.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
We know sin(π/2 - Ф) = cosФ and cos(π/2 - Ф) = sinФ.
sin23° = cos(90° - 23°) = cos67°.
cos41° ≠ sin41°.
cos58° = cos(180° - 58°) = cos122°.
