An engineer draws a scale model of a building.
• The scale of the drawing is 1 inch = 2.5 feet.
• On the drawing, one wall is 30 inches long.
What is the length of the actual wall?
Answer:
75 feet
Step-by-step explanation:
[tex]\frac{2.5ft}{1in} = \frac{x}{30in} \\[/tex]
By using a proportion we can solve this problem.
By isolating x we get x = 2.5(30) so x = 75.
Thus if the wall is 30 in in the model it is 75 feet in actuality.
(y+3)=−34(x−4) find the point and the slope
Answer:
Slope: -34
Point: (4, -3)
Step-by-step explanation:
This equation is written in point-slope form. The equation of a line in point-slope form is written as (y - y_1) = m(x - x_1).
x_1 and y_1 are the x and y coordinates of one point.m is the slope of the line.We are asked to find the point and slope of (y + 3) = -34(x - 4). We can automatically determine that the slope is -34 because that's where the variable, m, is. Next, we know that the x-coordinate is 4 because it's in the place of x_1. Lastly, the y-coordinate is -3 because it changes the subtraction sign to an addition sign, and it's in the place of y_1. Thus, the point would be (4, -3).

Choose the graph that matches the given equation y = 2sin(x – π) + 2.
Answer: D
Answer:
The graph that matches the equation y = 2sin(x – π) + 2 is D
Step-by-step explanation:
To determine which graph matches the given equation y = 2sin(x – π) + 2. We will determine the values of y for range of values of x from -2π to 5π.
When x = -2π
From
y = 2sin(x – π) + 2
Then
y = 2sin(-2π – π) + 2
y = 2sin(-3π) + 2
(NOTE: π = 180°)
∴ y = 2sin(-540) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = -π
Then
y = 2sin(-π – π) + 2
y = 2sin(-2π) + 2
y = 2sin(-360) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 0
Then
y = 2sin(0 – π) + 2
y = 2sin(-π) + 2
y = 2sin(-180) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = π
Then
y = 2sin( π– π) + 2
y = 2sin(0) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 2π
y = 2sin(2π – π) + 2
y = 2sin(π) + 2
y = 2sin(180) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 3π
y = 2sin(3π – π) + 2
y = 2sin(2π) + 2
y = 2sin(360) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 4π
y = 2sin(4π – π) + 2
y = 2sin(3π) + 2
y = 2sin(540) + 2
y = 2(0) +2
y = 0 + 2
y =2
When x = 5π
y = 2sin(5π – π) + 2
y = 2sin(4π) + 2
y = 2sin(720) + 2
y = 2(0) +2
y = 0 + 2
y =2
The only graph that corresponds to the tested values of x is the last graph (D)
Hence, the graph that matches the equation y = 2sin(x – π) + 2 is D.
The graph of the given equation is given by option D) and this can be determined by using the rules of transformation.
Given :
Equation -- [tex]y = 2\sin(x-\pi)+2[/tex]
The following steps can be used in order to determine the graph that represents the given equation:
Step 1 - Write the given equation.
[tex]y = 2\sin(x-\pi)+2[/tex]
Step 2 - Now, draw the graph of (sin x) and then translate it by a factor of [tex]\pi[/tex] in the right direction. So, the graph obtained is the graph of [tex]\sin(x-\pi)[/tex].
Step 3 - Now, stretch the graph of [tex]\sin(x-\pi)[/tex] by a factor of 2. So, the graph obtained is the graph of [tex]2\sin(x-\pi)[/tex].
Step 4 - Now, translate the graph of [tex]2\sin(x-\pi)[/tex] by a factor of 2 in the upward direction. So, the graph obtained is the graph of [tex]2\sin(x-\pi)+2[/tex].
Therefore, the correct option is D).

Solve this inequality for n.
14< n - 22
thanks ^^
Answer:
n = 36
Step-by-step explanation:
First, isolate the variable. Then, use the opposite operations to manipulate the inequality, whatever you do to one side you must to do the other, solve the right side to find your variable.
n - 22 + 22 < 14 + 22
n = 36
Write the explicit equation for this sequence. 4, 7.5, 11, 14.5,
18...
======================================================
Work Shown:
a = 4 is the first term
d = 3.5 is the common difference (we add this to each term to get the next term)
f(n) = nth term of arithmetic sequence
f(n) = a + d*(n-1)
f(n) = 4 + 3.5(n-1)
f(n) = 4 + 3.5n - 3.5
f(n) = 3.5n + 0.5
------------------------
As a check, we could plug in n = 1 to get
f(n) = 3.5n+0.5
f(1) = 3.5(1)+0.5
f(1) = 4
Showing that 4 is the first term. Now let's try n = 2
f(n) = 3.5n+0.5
f(2) = 3.5(2)+0.5
f(2) = 7.5
Which matches with the sequence also.
I'll let you confirm the other terms.
(a-b) (c-d). Please give steps :c
Answer:
ac - ad - bc + bd
Step-by-step explanation:
There aren't very many steps to show, but I'm assuming that you needed to multiply out the equation. So for this, you would use FOIL which means first, inner, outer, last.
I think of it as multiplying the a with c and d, and then multiplying the b with the c and d. When you do this, you get ac - ad - bc + bd.

A sphere has a volume of 13.04 cm3.
Calculate the radius of the sphere.
Answer:
[tex]r=1.46 \textsf{ cm (nearest hundredth)}[/tex]
Step-by-step explanation:
Volume of a sphere = [tex]\dfrac43\pi r^3[/tex]
Given volume = 13.04 cm³
[tex]\implies 13.04=\dfrac43\pi r^3[/tex]
Multiply both sides by 3/4:
[tex]\implies 9.78=\pi r^3[/tex]
Divide both sides by [tex]\pi[/tex]:
[tex]\implies \dfrac{9.78}{\pi}=r^3[/tex]
Cube root both sides:
[tex]\implies r=\sqrt[3]{\dfrac{9.78}{\pi}}[/tex]
[tex]\implies r=1.460146149...[/tex]
[tex]\implies r=1.46 \textsf{ cm (nearest hundredth)}[/tex]

Answer:
x = 32
Step-by-step explanation:
180 - 110 (y) = 70
so corner b = 70 degrees
360 - 282 = 78 (282 = z)
70 + 78 = 148
180 - 148 = 32
180 because all triangles angles add up to 180 degrees
so therefore x = 32 degrees
