7 cameras cost $308. The cost of each camera is the same. What is the cost of each camera?
Answers
Answer:
$44
Step-by-step explanation:
Hello!
It said that 7 cameras cost $308, right?
If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:
7x = 308.
If 7x = 308, it would be
308/7 =
44.
So, $44 is the answer.

Answers
Answer:
3/5, 4/5, 3/4
Step-by-step explanation:
First BC is 12 because of the Pythagorean Theorem. I use sohcahtoa to remember. sine is the side opposite of the angle divided by the hypotenuse of the triangle so 12/20 which is 3/5. cosine is adjacent / hypotenuse so 16/20 which is 4/5, and lastly tangent is opposite / adjacent which is 12/16 which is 3/4
The sine, cosine and the tangent of angle should be \(3\div 5, 4\div 5, 3\div 4\).
Calculation of the sine, cosine, and tangent:Here first we determine the BC by applying the Pythagorean Theorem.
\(= 20^2 - 16^2\\\\= 400 - 256\\\\= 144\)
So the BC should be 12
hence, based on this, we can say that The sine, cosine and the tangent of angle should be \(3\div 5, 4\div 5, 3\div 4\).

constant, so the height is 165 pixels. What is the scale factor of the
dilation? What is the base of the pennant?
~~~~~~~~~~~~~~
pls help T-T
Answers
Answer:
Base of the Pennant = 330 pixels
Scale Factor =0.6
Step-by-step explanation:
The base measure of the pennant on screen is 550 pixels.
The height is 275 pixels.
\(A$spect Ratio=\dfrac{Base}{Height}=\dfrac{550}{275} =2:1\)
If Charlotte resizes the pennant, keeping the aspect ratio constant.
Height = 165 pixels
Therefore:
\(\dfrac{Base}{165}=\dfrac{2}{1} \\\\$Base= 2 *165 =330\)
Therefore, the scale factor of the dilation \(=\dfrac{330}{550}= \dfrac{165}{275}=0.6\)
Base of the Pennant = 330 pixels
Scale Factor =0.6
Let f(x)=6x2+18x. Answer the following questions. 1. Find the x intercepts of the parabola. Intercepts (separate with commas): x=2. Find the vertex of the parabola. Write the vertex as a point (a,b) where a and b are numbers.
Answers
The x-intercept is -3 and the vertex of the parabola is (-1.5, -13.5).
What is vertex?The intersection of two lines, two line segments, or any other suitable arrangement of rays, segments, and lines that results in two straight "sides" coming together at one location is known as an angle's vertex.
The x coordinate of the vertex is given as:
x = -b/2a= -18/ 2(6)= - 1.5
The y coordinate of the vertex is given as:
y = f(- 1.5)
f(- 1.5) = 6(- 1.5)² + 18(- 1.5) = 13.5 - 27= -13.5
Hence, the vertex of the parabola is (-1.5, -13.5).
The x intercept is found by substituting the value of y = 0 in the function:
0 = 6x² + 18x
0 = 6x (x + 3)
x + 3 = 0
x = -3
Hence, the x-intercept is -3 and the vertex of the parabola is (-1.5, -13.5).

Answers
Answer:
y=4x-16
Step-by-step explanation:
We want to find the equation of the line in the form y=mx+c, where m is the slope and c is the y-intercept.
If the lines are parallel, their slopes will be the same. The slope of y=4x+1 is 4.
Our equation is now y=4x+c. Sub in point P to get c:
4=4(5)+c
4=20+c
c=-16

Erin weighs 135 pounds and is gaining ½ pound each week. Miranda weighs 143 pounds and is losing ¼ pound each week. Write an equation that could be used to determine x, the number of weeks that it will take until the two girls weigh the same amount?
Answers
Answer:
10.66 weeksStep-by-step explanation:
Number of weeks is x
135 + 1/2x = 143 - 1/4x1/2x + 1/4x = 143 - 1353/4x = 8x = 32/3 = 10.66 weeksAnswer:
\(135+\frac{1}{2}x=143-\frac{1}{4}x\)
Step-by-step explanation:
Let E represent Erin’s weight, and let M reprevent Miranda’s weight.
And let x represent the amount of week that passes.
Eric is currently 135 pounds. However, she is gaining 1/2 pounds per week x.
Hence, we can write the following equation:
\(D=135+\frac{1}{2}x\)
Miranda currently weights 143 pounts. However, she is losing 1/4 pounds per week x.
Since she is losing weight, 1/4 is negative. Hence:
\(M=143-\frac{1}{4}x\)
When the two girls weigh the same, D=M. Thus:
\(D=M\)
Substitute them for their respective equations to acquire:
\(135+\frac{1}{2}x=143-\frac{1}{4}x\)
Notes:
To solve, first eliminate the fractions by multiplying everything by 4. This yields:
\(540+2x=572-x\)
Add x to both sides. Subtract 540 from both sides:
\(3x=32\)
Divide both sides by 3:
\(x=32/3\approx10.67\)
Hence, it will take about 11 weeks for the girls to weigh the same.

How to determine the vertex form of a quadratic equation?In Mathematics, the vertex form of a quadratic function is represented by the following mathematical equation:
f(x) = a(x - h)² + k
Where:
h and k represents the vertex of the graph.a represents the leading coefficient.Based on the information provided about the vertex (0, -7) and other points (-3, 2), we can determine the value of a as follows:
f(x) = a(x - h)² + k
2 = a(-3 - 0)² - 7
2 + 7 = 9a
9 = 9a
a = 1
Therefore, the required quadratic function in vertex form is given by:
h(x) = a(x - h)² + k
h(x) = (x - 0)² - 7

Assuming that the equations define x and y implicitly as differentiable functions x = f(t), y=g(t), find the slope of the curve x = f(t), y = g(t) at the given value of t.
x=t^5 + t, y + 3t^5 = 3, x + 13, t= 3 The slope of the curve at t= 3 is
Answers
To find the slope of the curve at t=3, we first need to find the values of x and y at t=3 using the given equations.
x = (3)^5 + 3 = 246
y + 3(3)^5 = 3
y = -1347
Next, we can differentiate both equations with respect to t to get the following:
dx/dt = 5t^4 + 1
dy/dt = -15t^4
At t=3, we get
dx/dt = 5(3)^4 + 1 = 454
dy/dt = -15(3)^4 = -1215
Therefore, the slope of the curve at t=3 is given by dy/dx = (dy/dt)/(dx/dt) = (-1215/454) ≈ -2.68. This means that the curve is decreasing (sloping downwards) at t=3.
