Answer: $1640

Step-by-step explanation:

Since the salesperson's commission rate is 4%, therefore the commission from the sale of $41,000 worth of furnaces will be calculated as follows:

= 4% × $41000

= 4/100 × $41000

= 0.04 × $41000

= $1640

Therefore, the commission is $1640.

Answer:

positive

Step-by-step explanation:

negative slopes go from right to left; this line goes from left to right

0; the line isn't completely horizontal

undefined; the line isn't completely vertical

Answer:

[tex] \sqrt{137} [/tex]

Step-by-step explanation:

11.7

Answer:

the ans is 63°

Step-by-step explanation:

94°+24°+x(suppose)=180°(being a triangle)

x=63°

Answer:

its 63

Step-by-step explanation:

117 would be above 90 degreesand clearly its smaller than a 90 degree angle, meaning its 63 or 67 but 94+23=117 and (a full angle which is 180) 180-117 which gives u 63

Answer:

Solution given:

the equation of a circle is:

x²+y²-6x-2y+4=0

x²-2*x*3+3²+y²-2y+1²-1²+4=0

(x-3)²+(y-1)²=9+1-4

(x-3)²+(y-1)²=6

comparing above equation with

(a-h)²+(y-k)²=r²

we get

centre (h,k)=(3,1)

radius=√6

option first

(3,1), r = √6 is a required answer.

Answer:

(3,1), r = √6 is a required answer.

Answer:

B, E

Step-by-step explanation:

A would be wrong because the second part (up 1) would give you (5,1) The origin is (0,0)

B is correct because (5,0) has a 5 as the x coordinate

C is wrong because the y coordinate is 0

D is wrong because A is on the x since the y coordinate is 0

E is correct because (5,0) has a 5 on the x and a 0 on the y

Answer:

0.91

Step-by-step explanation:

The scatterplot shows a strong positive correlation which almost forms a perfect line.

The most appropriate correlation would be 0.91.

If the correlation was 0.21 then the plots would be more scattered.

Hope this helps you.

Point E is exterior to APD

Answer:

Angle APE is exterior to APD

because it's outside angle APD

Answer:

D. Zero product of multiplication

Step-by-step explanation:

The given equation is presented as follows;

Given: x² + 6·x + 8 = 0

By factorization, to find numbers represented by variables, 'a' and 'b', such that  a + b = 6 and a×b = 8, we have, a = 2, and b = 8 as a possible solution by observation

Step 1: (x + 2)·(x + 4) = 0

Given that (x + 2) × (x + 4) = 0, we have

Step 2: x + 2 = 0 or x + 4 = 0, by zero product of multiplication

The zero-product property states that the when two non zero numbers are multiplied, the result is nonzero

Therefore, when two numbers are multiplied, and have a result of zero, for example, i × j = 0, then, either, i = 0, or j = 0

By the zero-product rule, either, (x + 2) = 0, or (x + 4) = 0

Therefore, we have;

Therefore;

Step 3: x = -2 or x = -4

The property of real numbers Felipe's use for step 2 is the Zero product of multiplication.

Answer:

2 (real) solutions.

Step-by-step explanation:

A quadratic always has two solutions, whether they are real or complex.

Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).

In the case of

x^2+3x = 3, or

x² + 3x -3 = 0

we apply the quadratic formula to get

x =  (-3 +/- sqrt(3^2+4(1)(3))/2

to give the two solutions

{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}

both of which are real.

Answer:

Step-by-step explanation:

The x intercepts are 0 and

1000 - 2x = 0              given condition

1000 = 2x                   Divide by 2

500 = x

So the two intercepts are 0,0 and 500,0

The intercepts mean that for (0,0) the phone company hasn't charged anything, yet. For 500,0 the phone company can sell a single phone -- not when they cost 500 dollars apiece.

The answer to the B part is completing the square.

r(x) = - 2x^2 + 1000x

r(x) = -2(x^2 - 500x )

1/2 ( 500) = 250

250^2 is what you put inside the bracket's to complete the square.

r(x) =  - 2(x^2 - 500x + 250^2) + 2*250^2

r(x) = -2(x - 250)^2 + 2*62500

r(x) = - 2(x - 250)^2 + 125000

They should sell their phones at 250 dollars a piece. The total revenue is 125000. Your graph shows exactly the same thing.

Answer:

Step-by-step explanation:

The perimeter is the sum of the side lengths. Those that are unmarked are assumed to match the length of the nearest parallel side.

Clockwise from upper left, the perimeter is ...

  P = 8 + 5 + 4 + 4.5 + 15 + 5.6 + 4 + 5

  P = 51.5 . . . feet

__

The area can be figured using the formulas for area of a parallelogram, rectangle, and trapezoid. These are, respectively, ...

parallelogram area = (8 ft)(3 ft) = 24 ft²

rectangle area = (8 ft)(4 f) = 32 ft²

trapezoid area = (1/2)(8 ft +15 ft)(4 ft) = 46 ft²

Then the total area of the figure is ...

  A = 24 ft² +32 ft² +46 ft²

  A = 102 ft²

_____

Additional comment

The figure shown is impossible. The trapezoid side lengths and height are consistent with a bottom base of length 14, not 15.

Answer:

A -2*-2 ≠- 4

Step-by-step explanation:

sqrt(-4)

The answer is an imaginary number

-2*-2 = 4 not -4

Answer:

[tex]\sqrt{-4} \neq -2 \\[/tex]  because -2 times -2 equals 4 not -4.

Therefore A. [tex]-2^{2}\neq 4[/tex] is the answer to this question.

Step-by-step explanation:

If you divide 228 by 8, you will get 28.5. The 0.5 into a fraction would be 1/2. Half of 8 would be 4. In the end, there should be 28 full 8-ounce cups and one cup with 4 ounces.

Answer:

28, 44, 22

Step-by-step explanation:

a+b+c = 94

2×c = b

a = c+6

=>

c+6 + 2×c + c = 94

4×c + 6 = 94

4×c = 88

c = 22

=>

b = 2×22 = 44

a = 22 + 6 = 28
