Step-by-step explanation:
Given,
S = 4LW + 2WH
S = 138
L = 9
W = 3
so value of H,
→ 138 = 2(9)(3) + 2(3)H
→ 138 = 54 +6H
→ 6H = 138 - 54 = 84
→ H = 84/6 = 14
therefore, value of H is 14.

Write an equation for the line , in point slope form that passes through the following. points: (5, - 3) (- 2, 6)
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The required equation is :
[tex]y + 3 = - \dfrac{9}{7} (x - 5)[/tex][tex] \huge \boxed{ \mathfrak{Explanation}}[/tex]
Let's find the slope (m) of the line :
[tex] \mathrm{ \dfrac{y2 - y1}{x2 - x1} }[/tex][tex] \mathrm{ \dfrac{6 - ( - 3)}{ - 2 - 5} }[/tex][tex] \dfrac{6 + 3}{ - 7} [/tex][tex] - \dfrac{9}{7} [/tex]now, let's find the equation in point slope form :
[tex] \mathrm{y - y1 = m(x - x1)}[/tex][tex]y - ( -3 ) = - \dfrac{ 9}{7} (x - 5)[/tex][tex]y + 3 = - \dfrac{ 9}{7} (x - 5)[/tex]or it can be more simplified as :

n = 4 and p = 6? MP 2
A -2
B
2
C 3
D 3.6
O E 6
Answer:
2
Step-by-step explanation:
mn + p = m + 3n, n = 4 and p = 6
m(4)+6=m+3(4)
4m+6=m+12
4m=m+6
3m=6
m=2
Answer:
B) 2
Step-by-step explanation:
Step 1: Plug in the values of n and p.
[tex]m(4) + 6 = m + 3(4)[/tex] [tex]4m + 6 = m + 12[/tex]Step 2: Subtract m from both sides.
[tex]4m + 6 - m = m + 12 - m[/tex] [tex]3m+6=12[/tex]Step 3: Subtract 6 from both sides.
[tex]3m + 6 - 6 = 12 - 6[/tex] [tex]3m = 6[/tex]Step 4: Divide both sides by 3.
[tex]\frac{3m}{3} = \frac{6}{3}[/tex] [tex]m = 2[/tex]Step 5: Check if solution is correct.
[tex](2)(4)+(6)=(2)+3(4)[/tex] [tex]8 + 6 = 2 + 12[/tex] [tex]14 = 14[/tex]Therefore, the answer is B) 2.

9514 1404 393
Answer:
a) x = (√5 -1)/2 ≈ 0.618034
b) 1/x = (√5 +1)/2 ≈ 1.618034
Step-by-step explanation:
Given:
x/(1 -x) = 1/x
Find:
Exactly, and as a decimal approximation, ...
a) x, using the quadratic formula
b) 1/x
Solution:
a) We can multiply the given equation by x(1 -x) to obtain ...
x² = 1 -x
x² +x -1 = 0 . . . . . . add x-1
The coefficients for use in the quadratic formula are a=1, b=1, c=-1. The solution using the quadratic formula is ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-1\pm\sqrt{1^2-4\cdot1\cdot(-1)}}{2\cdot1}=\dfrac{-1\pm\sqrt{5}}{2}[/tex]
We are only interested in the positive solution, which is ...
[tex]\boxed{x=\dfrac{\sqrt{5}-1}{2}\approx0.618034}[/tex]
__
b) The quadratic we developed in the first part can be rearranged like this:
x² +x = 1 . . . . . . add 1 to both sides
x(x +1) = 1 . . . . . factor out x
x +1 = 1/x . . . . . .divide by x
Then to find the value of 1/x, we simply need to add 1 to the value of x we have:
[tex]\dfrac{1}{x}=\dfrac{\sqrt{5}-1}{2}+1=\dfrac{\sqrt{5}-1}{2}+\dfrac{2}{2}=\dfrac{\sqrt{5}-1+2}{2}\\\\\boxed{\dfrac{1}{x}=\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]
Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain.
Answer:
See belowStep-by-step explanation:
Correct way of using the formula:
I = 600*(7/100)(2) = 84The error was using 7 instead of 7/100 or 0.07 as percent value. She would get $8400 instead of $84.
Given :-
Juanita borrowed $600 .Rate of Interest = 7% .Time = 2yrs .To find :-
Error made by her.Answer :-
As we know that the formula for Simple interest is ,
SI = P*R*T / 100Substitute ,
I $600* 7 * 2 / 100 I = $ 84 .So here she did not write 7 % as 7/100 instead she wrote 7 .
Draw a possible function that satisfy the given domain and range
9514 1404 393
Answer:
see attached.
Step-by-step explanation:
Your graph demonstrates a possible function, but it has the domain and range swapped.
__
The domain is the horizontal extent, so your line must end at x=-9 on the left and x=6 on the right.
The range is the vertical extent, so the function must extend from -4 at the bottom to +8 at the top.
The attachment shows a linear function with those characteristics.
jeff makes the generalization that a 10s fact can be broken into two 5s facts. write an equation to test his generalization
Expressions can be simplified by breaking it down into several sub expressions.
The equivalent expressions are: [tex]\mathbf{10s= 2 \times 5s }[/tex] or [tex]\mathbf{10s= 5s \times 2}[/tex] or [tex]\mathbf{10s= 5s + 5s}[/tex]
The original expression is:
[tex]\mathbf{Expression = 10s}[/tex]
Express 10s as 5s + 5s
[tex]\mathbf{10s= 5s + 5s}[/tex]
Apply distributive property
[tex]\mathbf{10s= 5s(1 + 1)}[/tex]
Add 1 + 1
[tex]\mathbf{10s= 5s \times 2}[/tex]
Rewrite as:
[tex]\mathbf{10s= 2 \times 5s }[/tex]

The amplitude of this sine wave is 2 denoted by the coefficient -2 in front of the sin(x). The negative of the coefficient denotes that the sine wave is the opposite of the standard sine wave.
You are an electrician working in an industrial plant. A circuit contains eight incandescent lamps connected in series across 480 volts. One lamp has burned out, and you must determine which one is defective. You have available a voltmeter, ammeter, and ohmmeter. Which meter would you use to determine which lamp is defective in the shortest possible time? Explain how you would use this meter and why.
The burnt out bulb is located between two points in the circuit that have a
discontinuity.
The meter that can determine the defective lamp in the shortest possible time is the ohmmeterThe ohmmeter can be used iteratively to determine the defective bulb because the ohmmeter checks for continuity between two points and the process is repeated to locate the burned out bulb.Reasons:
The process and steps to determine the lamp that has burned out;
The given arrangement of the bubs = Series arrangement
Therefore;
A burn out of a bulb, causes a discontinuity by opening the circuit and to current flow.
The meter to use is that determine the defective lamp is one that checks for discontinuity, or an open circuit, which is the presence of infinite resistance, which requires a resistance meter;
Therefore, the ohmmeter (resistance meter) is the best meter to use
To determine the defective bulb;
Step 1: Switching off the power source or switch of the bulbsStep 2: Place the leads of the ohmmeter from one end of the circuit to after the middle bulb in the series, which is between the 4th and the 5th bulb Step 3: Check for continuity on the ohmmeterStep 4: If there is continuity, repeat the test on the other half of the circuit.Step 5: If there is discontinuity, repeat the test across each pair of adjacent bulbs within the first half, to find the burnt out bulb.Replace the bulb across which there is a discontinuity and switch on the power source to test the the circuit.Learn more here;
