Step-by-step explanation:
The question is incomplete. Find the complete question a=below;
A golf ball is hit with a club from the ground on a flat surface. The height of the ball, h(t), in feet, t seconds, after it was hit can be modeled by the function h(t)=40t-16t2. After how many seconds does the golf ball strike the ground?
The ball strikes the ground when the height h(t) = 0. To get the time wen the golf ball strikes the ground, we will substiute h = 0 into the modeled equation and calculate t as shown;
h(t)=40t-16t2
0 h(t)=40t-16t2
40t-16t² = 0
add 16t² to both side
40t-16t²+16t² = 0+16t²
40t = 16t²
40 = 16t
divide both sides by 16
t = 40/16.
t = 2.5secs
Hence the golf ball hit the ground after 2.5secs
Answer:
when the ball is hit as 0 second it has a height of 0 feet (because it hasnt done anything yet). The ball's height increases until it reaches its maximum height of 40 feet after 1.25 seconds (40t= 2.5/2). The balls height then decreases until it reaches 2.5 seconds after it was hit.
Solve the equation 5x+(-2)=6x+4
Answer:
x = -6
Step-by-step explanation:
Step 1: Write out equation
5x + (-2) = 6x + 4
Step 2: Simplify
5x - 2 = 6x + 4
Step 3: Subtract 5x on both sides
-2 = x + 4
Step 4: Subtract 4 on both sides
-6 = x
Step 5: Rewrite
x = -6
Answer:
x = -6
Step-by-step explanation:
[tex]5x+(-2)=6x+4[/tex]
Open the parenthesis
[tex]+(-2) =-2\\\\5x -2 =6x+4[/tex]
Collect like terms and simplify
[tex]5x-6x =4+2\\-x =6[/tex]
Multiply through by -1
[tex]-1(-x)=-1(6)\\\\x = -6[/tex]
3a+8 7 anyone know the answer?
Answer:
if you put 3a+87 the answer is 3(a+29)... but if u put 3a+ 8/7 the answer is 1/7*(21a+8)
Step-by-step explanation:
On a coordinate plane, 2 lines are shown. Line P Q has points (negative 5, 3) and (5, 1). Line R S has points (negative 4, negative 2) and (0, negative 4).
Which statement best explains the relationship between lines PQ and RS?
They are parallel because their slopes are equal.
They are parallel because their slopes are negative reciprocals.
They are not parallel because their slopes are not equal.
They are not parallel because their slopes are negative reciprocals.
Given:
Line P Q has points (-5, 3) and (5, 1).
Line R S has points (-4, -2) and (0, -4).
To find:
The relationship between lines PQ and RS.
Solution:
If a line passing through two points, then the slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Line P Q has points (-5, 3) and (5, 1). So, slope of line PQ is
[tex]m_1=\dfrac{1-3}{5-(-5)}[/tex]
[tex]m_1=\dfrac{-2}{5+5}[/tex]
[tex]m_1=\dfrac{-2}{10}[/tex]
[tex]m_1=\dfrac{-1}{5}[/tex]
Line R S has points (-4, -2) and (0, -4). So, slope of line RS is
[tex]m_2=\dfrac{-4-(-2)}{0-(-4)}[/tex]
[tex]m_2=\dfrac{-4+2}{0+4}[/tex]
[tex]m_2=\dfrac{-2}{4}[/tex]
[tex]m_2=\dfrac{-1}{2}[/tex]
Slopes of two parallel lines are equal.
[tex]m_1\neq m_2[/tex]
They are not parallel because their slopes are not equal.
Therefore, the correct option is C.
Answer:
the correct answer is c

Leah scored a total of 18 points in the basketball game, and she scored p points in the second half of the game. Write an expression to determine the number of points she scored in the first half of the game. Then, find the number of points she scored in the first half of the game if she scored 2 points in the second half of the game.
Answer: 16 points for the first half game
Step-by-step explanation:
1st half = ?
2nd half= p
Total = 18
The expressions to get the score of the 1st game is 18 -p
If she scored 2points in the second half game that means p=2
To get the 1st half of the game you should do 18-2=16

1. Which conditional statement has a true truth value? a. If a shape is a quadrilateral, then it is a square. b. If the sum of two numbers is positive, then both the addends are positive. c. If an angle has a measure of 180 degrees, then it is an acute angle. d. If a figure is a square, then it has four sides.
Answer:
B I believe
Step-by-step explanation:
Find the measure of an angle if its measure is 26 degrees more than three times its compliment?
16
141
74
42
The complement = x
The angle we are finding = 3x + 26
Complementary angles are angles that add up to 90 degrees.
90 = x + 3x + 26
Combine like terms
90 = 4x + 26
Subtract 26 from both sides
64 = 4x
Divide both sides by 4
16 = x
The angle we are trying to find = 3(16) + 26 = 48 + 26 = 74 degrees

Answer:
P=40
Step-by-step explanation:
find the distance between each vertices:
between the following points to find the length of each sides, octagon has 8 sides , since it is regular pentagon the distance between each vertices =5
the length of each side of octagon=5
to check :d=√(x2-x1)²+(y2-y1)²
(-2,-4) and (1,0) , d=√[(1-(-2)]²+(0+4)² =√3²+4², d=5
(1,0) and (1,5) , d= 5
(1,5) and (-2,9) , d=5
(-2,9) and (-7,9) , d=5
(-7,9) and (-10,5) , d=5
(-10,5) and(-10,0) , d=5
(-10,0) and(-7,-4), d= 5
(-7,-4) and (-2,-4), d=5
perimeter of octagon = 8a ( a is the length of the side)

[tex]3(m - 5) + 11 = - 85[/tex]
Answer:
Bro this some alien hyroglyphics
Step-by-step explanation:
Answer:
m = - 27
Step-by-step explanation:
Given
3(m - 5) + 11 = - 85 ← distribute and simplify left side
3m - 15 + 11 = - 85
3m - 4 = - 85 ( add 4 to both sides )
3m = - 81 ( divide both sides by 3 )
m = - 27

What does a pre image mean
Answer:
i think it means pre image (plural pre images) (mathematics) For a given function, the set of all elements of the domain that are mapped into a given subset of the codomain; (formally) given a function ƒ : X → Y and a subset B ⊆ Y, the set ƒ−1(B) = {x ∈ X : ƒ(x) ∈ B}.

*Instead of rewriting PF to QF +43 in part (a), you could also leave PF as it is and rewrite QF as PF -43 after the line I labelled as equation 2. The working would be about the same, just that you would not need to add 43 again in picture 3 because we would be working with PF. (PF would be factorised out instead)

Answer:
≠
Step-by-step explanation:
10 * 7 - 3 ____ 10 * (7 - 3)
70 - 3 ____ 10 * (7 - 3)
67 ____ 10 * (7 - 3)
67 ____ 10 * 4
67 ____ 40
67 ≠ 40
Answer is ≠
this is because of the order you do a problem.
1. P - paranthesis
2. E - exponents
3. MD - multiplication division (whatever comes first)
4. AS - addition subtraction (whatever comes first)
There are no paranthesis in the first one so you multiply first.
There are paranthesis in the second one so you add first.
That gives you a different answer for each making it unequal.
