Step-by-step explanation:
The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration -
a, over time, t. Which is an equivalent equation solved for a?
Ofv=a
10-v=a
O a
(+v=a
o {+v=a
Answer:
A
Step-by-step explanation:
f = v + at
f - v = at
(f-v)/t = a
Answer:
(f - v) / t = a
Step-by-step explanation:
Solving for the equation for a means taking all integers or values on the other side of the equation for a
To do this we must do it mathematically.
f = v + at
f - v = at
(f - v) / t = a

Lateral Area
Surface Area
Answer:
a) Lateral area of the solid = 2011.43 [tex]cm^{2}[/tex]
b) Surface area of the solid = 2544 [tex]cm^{2}[/tex]
Step-by-step explanation:
a) Lateral area of the figure = 2[tex]\pi[/tex]rh
where; r is the radius of the cylinder, and h is its height.
Lateral area of the figure = 2 x [tex]\frac{22}{7}[/tex] x 10 x 32
= 2011.43 [tex]cm^{2}[/tex]
b) The surface area = 2[tex]\pi[/tex]r(r + h) - 2([tex]\frac{1}{2}[/tex] x b x h)
= 2[tex]\pi[/tex]r(r + h) - (b x h)
The height of the isosceles triangle can be determined by applying the Pythagoras theorem to have,
[tex]10^{2}[/tex] = [tex]6^{2}[/tex] + [tex]h^{2}[/tex]
100 = 36 + [tex]h^{2}[/tex]
[tex]h^{2}[/tex] = 100 - 36
= 64
h = [tex]\sqrt{64}[/tex]
= 8
h = 8 cm
The surface area of the solid = 2 x [tex]\frac{22}{7}[/tex] x 10 (10 + 32) - 12 x 8
= 2640 - 96
= 2544
The surface area of the solid is 2544 [tex]cm^{2}[/tex].

Step-by-step explanation:
If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d
Answer:
D = 25
Step-by-step explanation:
For 2 lines to be parallel, they must have the same sloe;
Given the coordinates (-2,4)and (5,D)
Slope = D-4/5-(-2)
Slope = D-4/5+2
Slope = D-4/7
Given the equation y = 3x + 4, comparing to y = mx+b
mx = 3x
m = 3
Hence the slope is 3
Equating the slopes
D-4/7 = 3
D-4 = 3*7
D-4 = 21
D = 21+4
D = 25
Hence the value of D is 25

Two functions are shown in the table below.
Function - 1,2,3,4,5,6
f(x) = −x2 + 4x + 12
g(x) = x + 8
Complete the table on your own paper, then select the value that is a solution to f(x) = g(x).
x = 6
x = 3
x = 5
x = 4
Answer:
[tex](d)\ x = 4[/tex]
Step-by-step explanation:
Given
[tex]f(x) = -x^2 + 4x + 12[/tex]
[tex]g(x) = x + 8[/tex]
Required
Find x such that: [tex]f(x) = g(x)[/tex]
This gives:
[tex]-x^2 + 4x + 12 = x+8[/tex]
Collect like terms
[tex]-x^2 + 4x -x + 12 -8=0[/tex]
[tex]-x^2 + 3x +4 =0[/tex]
Expand
[tex]-x^2 + 4x - x+4 =0[/tex]
Factorize
[tex]x(x - 4) - 1(x-4) = 0[/tex]
Factor out x - 1
[tex](x- 1)(x - 4)=0[/tex]
Solve:
[tex]x =1\ or\ x = 4[/tex]

A windshield wiper turns through an angle of 150°. The top of the blade traces the are with a 20-inch radius. How long is the
arc?
A. 52.36 inches
B. 75.4 inches
C. 0.1308 inches
D. 3000 inches
Answer:
A
Step-by-step explanation:
Arc length is given by the formula:
[tex]\displaystyle s=2\pi r\frac{\theta}{360^\circ}[/tex]
Where r is the radius and θ is the central angle, in degrees.
The windshield wiper has a radius of 20 inches and a central angle of 150°. Hence:
[tex]\displaystyle s=2\pi (20)\left(\frac{150}{360}\right)[/tex]
Use a calculator:
[tex]\displaystyle s=\frac{50}{3}\pi \approx52.36\text{ inches}[/tex]

the sum of two numbers is 8. the sum of the squares of the same two numbers is 40. what are the numbers?
Answer:
The numbers are 6 and 2
Step-by-step explanation:
Given this scenario, we can set up the following equations:
x + y = 8
x² + y² = 40.
___________
x + y = 8
y = 8 – x
(y)² = (8 – x)²
y² = (8 – x)²
x² + y² = 40
x² + (8 – x)² = 40
x² + 64 – 16x + x² = 40
2x² – 16x + 64 = 40
2x² – 16x = -24
2(x² – 8x) = -24
x² – 8x = -12
x² – 8x + 12 = 0
(x – 6)(x – 2) = 0
x = 6 or 2.
x + y = 8 →
(6 or 2) + y = 8
y = 8 – (6 or 2)
y = 2 or 6.
___________
x + y = 8 →
6 + 2 = 8 →
8 = 8 ✓
x² + y² = 40 →
6² + 2² →
36 + 4 = 40 →
40 = 40 ✓
URGENT PLEASE HELP!! a rectangle's area is 336 mm Its height is 16 mm. What is its bases?
Answer:
21mm
Step-by-step explanation:
Area = 336mm²
Height = 16mm
Base = ?
Area = Base × Height (Substitute numbers into the known variable)
336mm² = Base × 16mm ( Find the base,so divide
16mm on both sides)
Base = 336mm² ÷ 16mm
= 21mm

Answer:
0.512 ; - 0.538
Step-by-step explanation:
Using the standard linear regression relation :
y = bx + c
b slope ; c = intercept ; y = dependent ; x = independent variable.
For finalist between 2004 - 2014 ;
y = 0.024x - 0.328
x = 35
y = 0.024(35) - 0.328
y = 0.512
For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :
y = -0.015x - 0.328
x = 14.
y = -0.015(14) - 0.328
y = - 0.538
