Answer:
1. -5
2. 4
3. 10
Step-by-step explanation:
this equation is in vertex form. Points 1 and 2 are the coordinates of the center of the circle (5 is the x coordinate, -4 is the y coordinate). To find the center of the circle, take the values of the given (5, -4) coordinate, and switch their sign (5 becomes -5, -4 becomes 4).
to find part 3, you will need to plug in the values of the second coordinate (-3, 2).
If you need to find the radius of (3), find the square root of whatever answer you got.
1. (x-5)^2 + (y+4)^2 = ___
2. (-3-5)^2 + (2+4)^2 = ____
3. (-8)^2 + (6)^2 =___
4. 64+36 = 100

5. [tex]\sqrt{100} = 10\\[/tex]
the answer to 3 is 10
Margaret has some cows. The cows produce an average total of 11.9
litres of milk per day for 290 days. Margaret sells the milk in 0.5 litre
bottles. Work out an estimate for the total number of bottles that
Margaret will be able to fill with the milk.
Answer:
6902
Step-by-step explanation:
Total milk produced in 290 days = 11.9 x 290 = 3451 litres
If 1 bottle has a capacity of 0.5l, the number of bottles needed = 3451 / 0.5 = 6902 bottles

Secant AD and AE intersect in the exterior of a circle. ∠ BAC measures 27.42° and the measure of DE is 73.18°. Determine the measure of BC .
Answer:
BC = 18.34°
Step-by-step explanation:
The secant- secant angle BAC is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( DE - BC) = 27.42
[tex]\frac{1}{2}[/tex] ( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )
73.18 - BC = 54.84 ( subtract 73.18 from both sides )
- BC = - 18.34° ( multiply both sides by - 1 )
BC = 18.34°
Write an equation in point-slope form of the line through the point (−1, 2) and with slope m = 2.
A. y − 2 = 2(x − 1)
B. y + 2 = 2(x − 1)
C. y + 2 = 2(x + 1)
D. y − 2 = 2(x + 1)
Answer:
D. y - 2 = 2(x + 1)
Step-by-step explanation:
y - y₁ = m (x - x₁)y - 2 = 2 (x - (-1))
y - 2 = 2 (x + 1)

if the edges of a cube are 6 inch edges. What is the volume?
Answer:
Volume = 216
Step-by-step explanation:
Answer:
216 in³
Step-by-step explanation:
volume of a cube = [tex]a^{3}[/tex]
a = 6
[tex]a^{3} = 6^{3}[/tex]
[tex]6^{3}[/tex] or 6 x 6 x 6 = 216

(Answer is not -3)
Answer:
Look below.
Step-by-step explanation:
K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.
X Y
2 4
1 1
0 0
-1 1
-2 4
If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.
Solve for all values of x by factoring
Answer:
x= 0,5
Step-by-step explanation:
You have to move all the terms to the left side and set them equal to zero. Then set each factor equal to zero.

Three friends were playing a game of marbles. At the end of the game, Marcy had 25% of the marbles, Roger had21of the marbles, and Ann had the rest of the marbles. If there were 100marbles altogether, how many marbles did Ann have at the end of the game
Answer:
54
Step-by-step explanation:
total no. of marbles=100
no. of marbles Marcy had
=25% of 100
=25/100×100
=25
no. of marbles Roger had=21
Let the no. of marbles Ann had=x.
So, 25+21+x=100
46+x=100
x=100-46=54
Therefore, Ann had 54 marbles at the end of the game.
A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25, point, 25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.

PLS help me!!! (EASY) (CORRECT Answer GETS BRAINLIEST + 16 points!!)
Answer:
y = 2x + 2
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(0, 2) & (6, 14)
Plug in these values:
(14 - 2) / (6 - 0)
Simplify the parentheses.
= (12) / (6)
Simplify the fraction.
12/6
= 2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = 2x + b
b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.
Therefore, our b-value is 2.
Plug this into our equation.
y = 2x + 2

R
Towns P, Q and Rare connected by roads PQ, PR and QR.
PR is 15 km longer than PQ.
QR is three times as long as PR.
The total length of the three roads is 245 km
Work out the length of PQ.
Use x as the unknown in any working.
Your final line must say, PQ = ...
Pa
Answer: 37 km
Step-by-step explanation:
Given
The total length of the three roads is 245 km
Suppose the length of PQ is [tex]x\ km[/tex]
According to question
The Length of PR is [tex]x+15[/tex]
The length of QR is [tex]3(x+15)[/tex]
The Sum of PQ, PR, and QR is
[tex]\Rightarrow x+x+15+3(x+15)=245\\\Rightarrow 5x+60=245\\\Rightarrow 5x=185\\\Rightarrow x=37 km[/tex]
length of PQ=37 km
