Answer:
c) y+4=3(x+1)
Step-by-step explanation:
Answer:
C. [tex]y+4=3(x+1)[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
All the given equations are in point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where m is the slope and the given point is [tex](x_1,y_1)[/tex]1) Determine the slope of the line
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-1,-4) and (2,5)
[tex]=\frac{5-(-4)}{2-(-1)}\\=\frac{5+4}{2+1}\\=\frac{9}{3}\\=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y-y_1=m(x-x_1)[/tex] :
[tex]y-y_1=3(x-x_1)[/tex]
2) Plug the point (-1,-4) into [tex]y-y_1=3(x-x_1)[/tex]
[tex]y-(-4)=3(x-(-1))\\y+4=3(x+1)[/tex]
Therefore, the correct answer is C.
I hope this helps!

A jar contains 15 quarters, 9 dimes, 10 nickels and 6 pennies. A coin is selected at random, not replaced, then another coin is selected. Find the probability of the event. P(quarter, then penny)
Answer: 0.058
Step-by-step explanation:
Number of quarters = 15
Number of dimes = 9
Number of nickels = 10
Number of pennies = 6
Total number of coins = 40
The probability of selecting a quarter first will be 15/40 = 3/8
Since it's not replaced, there'll be 39 coins left and the probability of choosing a penny is 6/39 = 2/13
Therefore, P(quarter, then penny) will be:
= 3/8 × 2/13
= 6/104
= 0.058

(1/2) 4/? = ?
A :4/8
B:1/8
C:4/16
D:1/16
Answer:
A: 4/8
Step-by-step explanation:
1/2 is the same as 4/8 because if we divide 4 to both the numerator (4 divided by 4) and the denominator (8 divided by 2), we get 1 for the numerator and 2 for the denominator.
What is the volume of the prism in cubic inches ?
what is the surface area in square inches ?
Answer:
Step-by-step explanation:
Volume
V = B * h
B = 1/2 a * b
Solution
Area of Triangles = B = 1/2 * 6 * 8
Area of Triangles = B = 24 square inches
Volume = B * H
Volume = 24 * 12
Volume = 288 cu in
Surface Area
Triangles
Area of one triangle = 24 square inches [ See Above ]
Area of two triangles = 48 square inches
Left Side
Area = L * W
L = 12
W = 8
Area = 12 * 8
Area = 96
Right side
Area = L * W
L = 12
W = 6
Area = 12 * 6
Area = 72
Area Back
L = 12
W = 10
Area = 12 * 10
Area = 120
Total = 120 + 72 + 96 + 48 = 336 square inches

Step-by-step explanation:
The planet venus is on average 2.5x10^7 kilometers from earth. The planet mars is on average 2.25x10^8 kilometers from earth. What is the average distance from venus to mars?
Answer:
The average distance from venus to mars is 2.5x10⁸ kilometers.
Step-by-step explanation:
We know:
d₁: average distance between venus and earth = 2.5x10⁷ km
d₂: average distance between mars and earth = 2.25x10⁸ km
We can find the average distance from venus to mars as follows:
[tex] d_{t} = d_{1} + d_{2} [/tex]
First, we need to equal the base power 10 so we can sum both distances:
[tex]2.25 \cdot 10^{8} = 2.25 \cdot 10^{7} \times 10 = 22.5 \cdot 10^{7} km[/tex]
Now, average distance:
[tex]d_{t} = 2.5 \cdot 10^{7} + 22.5 \cdot 10^{7} = (2.5 + 22.5) \cdot 10^{7} = 25 \cdot 10^{7} km = 2.5 \cdot 10^{8} km[/tex]
Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.

If $3,200 is invested at a rate of 5.5%, compounded quarterly, calculate the value of the investment after
4 years. Round to the nearest dollar.
Hint: Use the formula below
A=P(1+r/n)^nt
Answer:
A = $13,366.37
A = P + I where
P (principal) = $10,000.00
I (interest) = $3,366.37
Step-by-step explanation:
Answer:
$3964
Step-by-step explanation:
A=P(1+r/n)^nt
So 3964(1+.055)^4
Comes out to 3964.238882. Then round

Suppose that a random parabola has a maximum vertex at (-7, 1). What
would be the value of the Axis of Symmetry for this parabola?
EXPLAIN
Answer:
x = -7 or y = 1
Step-by-step explanation:
Since we are not given the actual formula for the parabola, we do not know in which direction the parabola is facing. The axis of symmetry is the value of the line that splits the parabola perfectly down the middle, to calculate this we need to know in which direction the parabola is facing. Since we do not have this information and only have the maximum vertex we can provide the two possible values for the Axis of Symmetry, which would be the following...
x = -7 or y = 1

Please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
30 m
Step-by-step explanation:
Picture the question as a triangle
The length of the string is the hypotenuse, 60 m
The angle from the ground is 30
The right angle C is from the height of the kite to the ground
The missing angle A 60 is located on the top of the kite
now find b, the height
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(A)=adj/hyp
cos(A)=b/c
b=c*cos(A)
b=60*cos(60)
b=30

4x(x+2)+2(x+2)=0
(x+2)(4x+2)=0
either x=-2/4=-½
or
x=-2
So
It has 2 solution.

The circumference of a circle is 69.08 yards. What is the circle's radius? Use 3.14
Answer:
r = 11
Step-by-step explanation:
C = 2πr
69.08 = 2(3.14)r
69.08 = 6.28r
r = 69.08/6.28
r = 11

90° counterclockwise about the origin
Whats the coordinates
Answer:
see explanation
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , then
A (2, - 2 ) → A' (2, 2 )
B (4, - 1 ) → B' (1, 4 )
C (4, - 3 ) → C' (3, 4 )
D (2, - 4 ) → D' (4, 2 )

Answer:
The answer is A. 77.
Step-by-step explanation:
Using trigonometry formula
We know, tan = opposite/adjacent
So, tan x° = 13/3
=> x° = [tex]tan^{-1}[/tex](13/3)
∴ x° = 77.005° ≈ 77.01°

Becker and Kayla are members of the school chess team. They record the number of games they each play for 10 days. The data are shown below
Becker: 5,2,4,1,1,4,5,3,2,1
Kayla: 2,3,1,1,4,1,5,3,5,5
Based on the data, which estimate represents the mean of number of games chess team members play per day?
A.) 1
B.) 3
C.) 4
D.) 10
Answer:
B.) 3
Step-by-step explanation:
You add up all of the numbers from Beck which is 28. Now you do the same thing for Kayla, add up all the numbers from Kayla which equals 30. You add up their chess games 28 + 30 = 58 and then divide by the total number of days they played.. 20. 58/20 = 2.9. You round to the nearest tenth which would get you 3.
