Answer:
-19 and 3
Step-by-step explanation:
-19 x 3 = -57
-19 + 3 = -16
Answer:
Step-by-step explanation: To find the answer to "What two numbers have a product of 57 and a sum of 16?" we first state what we know. We are looking for x and y and we know that x • y = 57 and x + y = 16.
Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which This means that when we create one equation to solve the problem, we will have two answers.
To solve the problem, we take x + y = 16 and solve it for y to get y = 16 - x. Then, we replace y in x • y = 57 with 16 - x to get this:
x • (16 - x) = 57
Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 57 and a sum of 16. The numbers are:
5.35425
10.64575
That's it! The two numbers that have a product of 57 and a sum of 16 are 5.35425 and 10.64575 as proven below:
5.35425 • 10.64575 = 57
5.35425 + 10.64575 = 16

Step-by-step explanation:
first find out the area of sector ECF
π(10)² × 40°/360°
=100π×1/9
=100π/9 m²
now find the area of sector DCG
π(2)² × 40°/360°
=4π/9 m²*
so the area of the shaded region would be the big sector minus the small sector
so
100π/9 - 4π/9
=96π/9
=33.5 m² (3sig.fig.)
*Note that 4π/9 DOES NOT equal to 2π/3
4/9 DOES NOT EQUAL TO 2/3

So we know that x = 90º because it is a right angle. And angle B also has to be 47º because it is a reflection of angle C. And all the angles of any triangle are equal to 180º, so if we do 180-(90+47)=43. So now we know that y=43º and x=90º Your welcome, please give me brainlest.

Step-by-step explanation:
Half a dollar = $0.50
Eight dimes = $0.80
Six nickels = $0.30
Nine pennies = $0.09
Total = $0.50 + $0.80 + $0.30 + $0.09 = $1.69

What are the coordinates of the midpoint of AB if A (4, 6) and B(-8, 2)?
o (6, 4)
O (-6, 4)
O (-2, 4)
o (2, 4)
Answer:
(- 2, 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) , then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = A (4, 6 ) and (x₂, y₂ ) = B (- 8, 2 )
midpoint = ( [tex]\frac{4-8}{2}[/tex] , [tex]\frac{6+2}{2}[/tex] ) = ( [tex]\frac{-4}{2}[/tex] , [tex]\frac{8}{2}[/tex] ) = (- 2, 4 )
Midpoint be p(x,y)
P(x,y)=
[tex]\\ \sf\longmapsto \left(\dfrac{4-8}{2},\dfrac{6+2}{2}\right)[/tex]
[tex]\\ \sf\longmapsto \left(\dfrac{-4}{2},\dfrac{8}{2}\right)[/tex]

Dev ordered 10 ink cartridges and 1 box of copy paper for his office. The box of copy paper cost $45. He had a coupon for $2 off each ink cartridge. He spent a total of $175.
Based on the cost of the copy paper and the discount on ink cartridges, the cost of the ink cartridge is $15 each.
First find the amount paid for the ink cartridges:
= Total spent - cost of copy paper
= 175 - 45
= $130
He got a discount of $2 per cartridge. For 10 cartridges he got a discount of:
= 2 x 10
= $20
The cost of each ink cartridge is:
= (Amount spent on ink cartridges + Discount) / Number of cartridges
= (130 + 20) / 10
= $15 each
In conclusion, each cartridge cost $15.

A polynomial function has a root of –7 with multiplicity 2, a root of –1 with multiplicity 1, a root of 2 with multiplicity 4, and a root of 4 with multiplicity 1. If the function has a positive leading coefficient and is of even degree, which statement about the graph is true?
The graph of the function is positive on (2, 4).
The graph of the function is negative on (4, infinity).
The graph of the function is positive on (negative infinity, –7).
The graph of the function is negative on (–7, –1).
Answer:
C. The graph of the function is positive on (negative infinity, –7).Step-by-step explanation:
With given conditions we can state:
The graph is positive between (-∞, -7)∪(-7, -1)∪(4, +∞), since it touches -7 and is positive either side of it.The graph is negative between (-1, 2) and (2, 4), since it touches 2 and is negative either side of it.Overall shape is U as leading coefficient is positive and is of even degree.Comparing with the answer choices, correct choice is C.
