You just need to multiply 3762 with 54

Answer:

x = 120°

The triangle is an equilateral triangle and all the angles in an equilateral triangle equal 60°.

Straight lines have 180° angles.

180 -  60 = 120

Answer:

Step-by-step explanation:

Identity used: [tex]a^{2}-b^{2} = (a + b)(a -b)[/tex]

81 = 9*9 = 9²

a = x^2 and  b =9

Then again 9 = 3*3.In this way, (x² - 9 ) can be again factored

[tex]x^{4} - 81 = (x^{2})^{2}-9^{2}\\\\=(x^{2} + 9)(x^{2} - 9)\\\\=(x^{2}+9) (x^{2} -3^{2})\\\\= (x^{2} + 9}(x+3)(x-3)[/tex]

Step-by-step explanation:

line A and D are parallel because they have the same koeficient 3=3

line C is perpendicular to line A because

k1*k2=-1

3*(-1/3)=-1

which is a true statement

Answer:

a) Line D is parallel to line A

b) Line C is perpendicular to line A

Step-by-step explanation:

Line A has a slope of 3 and y intercept of 6

Line C is perpendicular to A as perpendicular lines have negative reciprocal slopes. Slope of C is -1/3

Line D is parallel to A as parallel lines have identical slopes but different y intercepts. Slope of D is 3 and y intercept is -1/3

Line B mirrors Line A over the y axis. It's slope is the negative of A and it has an identical y intercept.

Answer:

Step-by-step explanation:

ΔABD ≅ ΔACD    {A S A congreunt}

∠ADB ≅ ∠ADC   {CPCT}

∠ADB + ∠ADC = 180   {linear pair}

2∠ADB = 180

∠ADB = 180/2

∠ADB = 90

∠ADB = ∠ADC = 90.

So, now we can use Pythagorean theorem to find x

x² = 8² - 2²

   = 64 - 4 = 60

x = √60

Answer:

2

Step-by-step explanation:

f(x) starts at the orgin, (0, 0), and g(x) starts at (0, 2)

With this information we can decide that k is 2 as it moved the line up 2

Answer:

the answer is the third one

Step-by-step explanation:

Answer:

(2r-3)-4=37

or,(2r-3)=37+4

or,2r-3=41

or,2r=41+3

or,2r=44

or, r= 44/2

hence , r= 22

Answer:

$2.30

Step-by-step explanation:

Price- $15.18

Ounces- 6.6

$15.18 ÷ 6.6

=$2.30

Answer:

x = 1

Step-by-step explanation:

I'm going to convert this to decimal to make it easier to type

Since x = 1, there is no need to include it in the equation

1/4 - 8 = -7.75 + 12 = 4.25

-0.75 + 5 = 4.25

Answer:

By simplifying both sides of the equation, then isolating the variable.

X=1

Step-by-step explanation:

1/4*1-8+12=-3/4*1+5

a) [tex]-4\geq x\geq -1[/tex]

x <= -4 and x >= -1

b) [tex]2<x\leq 4[/tex]

x > 2 and x <= 4

c) [tex]3 > x > 9[/tex]

x < 3 and x > 9

d) [tex]-5 \leq x < 0[/tex]

x >= -5 and x < 0

Hope this helps!

Let's Simply :

Answer:

A.   Yes, there is a value that will maximize the profit overall x values. This is true when the functions C(x), R(x), and P(x) are often defined only for non-negative integers, that is, for x = 0, 1, 2, 3... . The reason is it is not logical to speak about the cost of producing −1 cars or the revenue generated by selling 3.62 refrigerators. Thus, each function may give rise to a set of discrete points on a graph.

The formulas for these questions are:

C(x) = cost of producing x units of the product

R(x) = revenue generated by selling x units of the product

P(x) = R(x) − C(x) = the profit (or loss) generated by producing and (selling x units of the product.)

B.  No, there is not an x-value that will maximize the profit over [0,1000]. This is true since 1,000 is the horizontal asymptote, which means that the line of the graph keeps traveling with the HA until the profits drop since we cannot produce anything more than 1,000 units of energy per day. The graph of this problem would be a horizontal asymptote at y = 1,000. The line of the graph would start at zero and increase until it reaches the asymptote at 1,000 and continues towards infinity.

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Answer:

x=2y

Step-by-step explanation:

y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.

Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.

One option (that I would use):

Ignore the decimals and multiply 13 x 916.

    9 1 6

  x    1 3

 2 7 4 8

 9 1 6 0

1 1 9 0 8

OK, now take into account there were a total of three digits to the right of decimal points (3, 1, and 6), so your answer also needs three digits to the right of your decimal point.

Answer 11.908

Answer:

y = -2/4x -5

Step-by-step explanation:

Assuming that the answer will be in slope intercept form, and not standard form. It would go a little like this:

Finding the slope:

y2 - y1/x2 - x1

-6 - (-4) / 2 -(-2)

-6 + 4 / 2 + 2

-2/4

Simplifying further, the slope would be: -1/2

The slope would be -1/2.

Now, checking desmos, the equation would be: y = -2/4x -5.
