Answer:
31 feet.
Step-by-step explanation:
It is mentioned in the question that
Height of baseball expressed in feet
T = time in seconds
Also
[tex]h= -16t^2+64t+3[/tex]
Now the time is 3.5 so put this value to the above equation
h = -16(3.5)^2 + 64(3.5) + 3
= -16(2.25) + 224 + 3
= -196 + 227
= 31
Therefore the height of a baseball is 31 feet and the same is to be considered

AC = 120. What
are AB and BC?
Answer:
AB = 42
BC = 78
Step-by-step explanation:
AB = 4x + 6
BC = 7x + 15
AC = 120
A to B plus B to C is the same distance as from A to C, which is 120.
AB + BC = AC
(4x + 6) + (7x + 15) = 120
4x + 7x + 6 + 15 = 120
11x + 21 = 120
Subtract 21 from both sides.
11x = 120 - 21 = 99
11x = 99
Divide both sides by 11.
x = 9
AB = 4x + 6 = 4*9 + 6 = 36 + 6 = 42
BC = 7x + 15 = 7*9 + 15 = 63 + 15 = 78
Answer:
AB = 42
BC = 78
Answer:
x = 9
AB = 42
BC = 78
Step-by-step explanation:
AB + BC = AC
4x + 6 + 7x + 15 = 120
11x + 21 = 120
11x = 99
x = 9
AB = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
BC = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

The map below shows the length of a proposed land bridge at Phil Hardberger Park. The length of the land bridge is represented by PH
in the map below.
P(2,55)
H(32, 15)
On the map, each unit represents 1 yard. To the nearest yard, what is the actual length of the land bridge from P to H?
A 50 yards
B. 150 yards
C. 78 yards
D. 234 yards
Answer:
A; the actual length of the land bridge from P to H is 50 yards
Step-by-step explanation:
Here in this case, given the coordinates of P and H, we want to calculate the actual length of the distance between the two points.
Mathematically, to calculate this distance, we make use of the distance formula;
D = √(x2-x1)^2 + (y2-y1)^2
In this case, (x1,y1) = (2,55) while (x2,y2) = (32,15)
Substituting these values
D = √(32-2)^2 + (15-55)^2
D = √(-30)^2 + (-40)^2
D = √(900 + 1600)
D = √(2,500)
D = 50 units
Now, we know that each units represent 1 yard, thus 50 units will represent 50 * 1 = 50 yards

Liza draws an angle that measures 150 degrees.She then draws a ray that divides the angle into 2 equal parts. What is the measure of each smaller angle?
Step-by-step explanation:
Liza draws an angle that measures 150 degrees.She then draws a ray that divides the angle into 2 equal parts
The given angle measures 150 degrees
She draw a ray that divides 150 degrees in to two equal angles
So we divide the angle 150 into two equal angles
[tex]\frac{150}{2} =75[/tex]
Two equal angles measures 75 degree each
So the measure of each smaller angle is 75 degrees
Answer:
75 degree
A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 210 feet (ft). If the wheel
rotates 45° counterclockwise and stops, how much does the height of the seat change?
Answer:
The change in the height of the seat of the Ferris wheel is a reduction in height of approximately 74.25 feet
Step-by-step explanation:
The given information are;
The position of the seat on the Ferris wheel = The center level of the wheel
The diameter of the Ferris wheel = 210 feet
The angle of rotation of the wheel = 45° counterclockwise
The height of a point on the Ferris wheel is given by the relation;
h = A·cos(b·x + c) + d
With regards to the question, we have;
h = The height of the seat of the Ferris wheel
A = The amplitude = 1/2 × The diameter of the wheel = 210/2 = 105 feet
360/b = The period
c = The phase shift = 90°
d = The mid line = 0
For a rotation of 45° counterclockwise or-45° clockwise, we have;
b·x = 45°, therefore;
h = 105 × cos(45° + 90°) + 0 = 105 × cos(135°) + 0
h = 105 × cos(135°) ≈ -74.25 feet
Therefore, the height of the seat of the Ferris wheel reduces by 74.246 feet.
In this exercise we have to know about rotation, therefore: the change in the height of the seat of the Ferris wheel is a reduction in height of approximately 74.25 feet.
The given information are:
The position of the seat on the Ferris wheel = The center level of the wheel. The diameter of the Ferris wheel = 210 feet The angle of rotation of the wheel = 45° counterclockwise
The height of a point on the Ferris wheel is given by the relation:
[tex]h = A*cos((b)(x) + c) + d[/tex]
With regards to the question, we have:
h = The height of the seat of the Ferris wheel
A = The amplitude = 1/2 × The diameter of the wheel = 210/2 = 105 feet
360/b = The period
c = The phase shift = 90°
d = The mid line = 0
For a rotation of 45° counterclockwise or-45° clockwise, we have;
[tex](b)(x) = 45\\h = 105 *cos(45 + 90) + 0 = 105 * cos(135) + 0\\h = 105 *cos(135) = -74.25 feet[/tex]
Therefore, the height of the seat of the Ferris wheel reduces by 74.246 feet.

i want to know what g is
Answer:
Step-by-step explanation:
2(5-4g) + 3g - 11 = 5(g-3) - 12 - 3g (remove the parantheses)
10 - 8g + 3g - 11 = 5g - 15 - 12 -3g (Calculate and collect like terms)
-1 - 5g = 2g - 27 (move the terms)
-5g -2g = 27 + 1 (collect like terms and calculate)
-7g = -26 (divide both sides)
so G = 26/7
Answer:
G=27/6
Step-by-step explanation:
2(5−4g)+3g−11=5(g−3)−12−3g
(2)(5)+(2)(−4g)+3g+−11=(5)(g)+(5)(−3)+−12+−3g
10+−8g+3g+−11=5g+−15+−12+−3g
(−8g+3g)+(10+−11)=(5g+−3g)+(−15+−12)
−5g+−1=2g+−27
−5g−1=2g−27
Step 2: Subtract 2g from both sides.
−5g−1−2g=2g−27−2g
−7g−1=−27
Step 3: Add 1 to both sides.
−7g−1+1=−27+1
−7g=−26
Step 4: Divide both sides by -7.
-7g/-7=-26/-7
g=26/7

Keys Per Minute recently hired Anne Bradford as a data entry clerk.Her starting rate of pay is $7.50 per hour and will increase to $8.00 per hour after 90 days. If her standard work week is 32 hours, what will her straight-time pay be 4 months from now ?
Answer:
$3904Step-by-step explanation:
From the question, since it will take 90 days that is 3 months for her hourly pay to increase to $8 per hour
we proceed to calculate her pay for the first 3 months
she works a total of 32 hours in a week
hence for three months, she would work 32*4*3= 384hours
therefore her pay for three months is= 7.5*384= $2880
Now the remaining one month her pay rate has been increased to $8 per hour
the number of hours in one month is 32*4= 128 hours
her pay would be 128*8= $1024
Her straight time pay for 4months is $2880+$1024 = $3904
