Answer:
The missing coordinate [tex]r[/tex] is 9.
Step-by-step explanation:
Given the points [tex]P(x,y) = (-3,-3)[/tex] and [tex]Q(x,y) = (5,r)[/tex], the slope of a line passing the two points ([tex]m_{PQ}[/tex]) is determined by equation of secant line:
[tex]m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}[/tex] (1)
[tex]m_{PQ} = \frac{r-(-3)}{5-(-3)}[/tex]
If we know that [tex]m_{PQ} = \frac{3}{2}[/tex], then the value of [tex]r[/tex] is:
[tex]\frac{3}{2} = \frac{r+3}{8}[/tex]
[tex]12 = r + 3[/tex]
[tex]r = 9[/tex]
The missing coordinate [tex]r[/tex] is 9.

Answer:
608
Step-by-step explanation:
The appropriate general formula here is a(n) = a(1) + (n -1)d, where d is the common difference. Here, d = +7. Thus:
a(92) = -29 + (92-1)(7) = 608

[tex] y_2 = 4x^2 [/tex]
[tex] x = 1 [/tex]
[tex] y_2 = 4(1)^2 = 4 = a [/tex]
a = 4
[tex] y_3 = 4^x [/tex]
[tex] x = 1 [/tex]
[tex] y_3 = 4^1 = 4 = b [/tex]
b = 4
[tex] y_1 = 4x [/tex]
[tex] x = 2 [/tex]
[tex] y_1 = 4(2) = 8 = c [/tex]
c = 8
[tex] y_3 = 4^x [/tex]
[tex] x = 2 [/tex]
[tex] y_3 = 4^2 = 16 = d [/tex]
d = 16
[tex] y_1 = 4x [/tex]
[tex] x = 3 [/tex]
[tex] y_1 = 4(3) = 12 = e [/tex]
e = 12
[tex] y_2 = 4x^2 [/tex]
[tex] x = 3 [/tex]
[tex] y_2 = 4(3)^2 = 36 = f [/tex]

Which is the equation of a line that passes through the point (-3, 5) with a slope
of -2/3
what is the distance between (0.-3) and (9.6)
Answer:
d = 12.7 when rounded to the nearest tenths
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (0, -3) and (9, 6)
d=√((9-0)²+(6-(-3))²)
d=√((9))²+(6+3))²)
d=√(81 + (9)²)
d = √162
d = 12.727...
d = 12.7 when rounded to the nearest tenths

A bookmark has an area of 21 square centimeters. Its perimeter is 20 centimeters. What are the dimensions of the bookmark?
Answer: The dimensions are 7cm and 3cm.
Step-by-step explanation:
The following equation can be deduced from the question
L × W = 21 ....... i
2L + 2W = 20 .......... ii
Divide equation ii through by 2
(2L + 2W = 20) / 2
L + W = 10 ....... iii
From equation iii
L = 10 - W ......... iv
Put equation iv into I
L × W = 21
(10 - W) × W = 21
10W - W² = 21
W² - 10W + 21 = 0
W² - 7W - 3W + 21 = 0
W(W - 7) - 3(W - 7) = 0
W - 3 = 0
W = 0+3
W = 3 centimeter
Since,
Length × Width = 21
Length = 21/3
Length = 7 centimeters
The dimensions are 7cm and 3cm.

Water freezes at 0 degrees Celsius. A student discovered that adding half a cup of salt to a gallon of water lowers its freezing temperature by 7 degrees Celsius. What is the freezing temperature of the gallon of salt water?
Answer:
-7°C
Step-by-step explanation:
Freezing point of water = 0°C
By adding salt, freezing point lowers by 7°C ;
The freezing point of salt water can be expressed as ;
Since temperature lowers :
Freezing point of salt water :
Freezing point of water - 7°C
0°C - 7°C
= - 7°C
The radius of a cylindrical water tank is 4 ft, and its height is 6 ft, what is the volume of the tank?
Answer:
96π cu ft.
Step-by-step explanation:
V = Bh B = area of the base h = height
The base is a circle, so [tex]B = \pi r^{2} = \pi 4^{2} = 16\pi[/tex]
V = 16π(6) = 96π cu ft.
The volume of the cylinder is 301. 6 cu. ft.
What is the volume of the cylinder?[tex]V=\pi \times r^2\times h[/tex]
where r is the radius of the cylinder and h is the height of the cylinder
For given question,
The radius of a cylindrical water tank is 4 ft, and its height is 6 ft,
[tex]\Rightarrow r=4~ft,~h=6~ft[/tex]
We need to find the volume of the cylinder.
Using the formula of the volume of the cylinder,
[tex]\Rightarrow V=\pi \times r^2\times h\\\\\Rightarrow V=\pi \times 4^2\times 6\\\\\Rightarrow V=\pi \times 16 \times 6\\\\\Rightarrow V =301.6~~cu.ft.[/tex]
Therefore, the volume of the cylinder is 301. 6 cu. ft.

If you want to bowl six games which ally is better show work
Answer:
Pinz
Step-by-step explanation:
So to set up the equation for Lanez:
y = 3.5 + 4.25x
Next we compare the prices for both overall by plugging 6 games in as x:
Lanez:
y = 3.5 + 4.25(6)
y = 3.5 + 25.5
y = 29
Pinz:
y = 3.75 + 4(6)
y = 3.75 + 24
y = 27.75
29>27.75
Lanez is more expensive with it costing $29 for a night as opposed to the $27.75 one would pay to play at Pinz.
