Answer:
3 secsStep-by-step explanation:
Given the height of the object as it drops from the observation deck expressed as;
h= -16t^2+152
To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;
8 = -16t^2+152
subtract 8 from both sides
8-8 = -16t^2+152-8
0 = -16t^2+144
0-144 = -16t^2
-144 = -16t^2
16t^2 = 144
Divide both sides by 16;
16t^2/16 = 144/16
t^2 = 9
t = √9
t = 3seconds
Hence it will take 3 seconds for the object to be 8 feet above the valley floor
Use the diagram to find lengths. BP is the perpendicular bisector of AC. CQ is the perpendicular bisector of BD. AB = BC = CD.
Answer:
hhhhhh i have no idea
Step-by-step explanation:
sorrrrrrryyyyyyyyyyy
Answer:
PC = 8
Step-by-step explanation:
Bisectors split things into equal parts. The bisector PB made AP and PC equal. So AP = 8, AP = PC, 8 = PC
find area and perimeter
pls show work
Step-by-step explanation:
ok so first you can split the object into 2 different shapes like the first picture.
next you can start with shape labeled 1
and the perimeter of that would be 5+5+4+4 =14
so the perimeter is shape 1 is 14
the area would be5×4 which is 20
now shape 2 the perimeter of that would be 8+8+2+2 which is 20
the area would be 8×2 which would be 16
so then you add the are and perimeter of each shape together
p= 14+20=34
a= 20+16= 36
Write the word sentence as an inequality. Then solve the inequality. Six times a number x is at least −24.
6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given sentence is Six times a number x is at least −24.
Whenever there is a word times means it is a product.
Atleast means greater than or equal to.
Let x be the number in inequality.
Six times a number x is 6x.
Six times a number x is atleast −24.
6x≥-24
6x≥-24 is the required inequality
Divide both sides by 6
x≥-4
Hence, 6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.

What is the slope intercept form of the equation 4x-8y=72
Answer:
y = 1/2x - 9
General Formulas and Concepts:
Alg I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: 4x - 8y = 72
Step 2: Find slope-intercept form
Subtract 4x on both sides: -8y = 72 - 4xDivide both sides by -8: y = -9 + 1/2xRewrite: y = 1/2x - 9Liana is studying the activity of nurse sharks. She starts at a position that is 25 feet below sea level. She rises 9 feet, then descends 12 feet to take a photo of a sleeping shark. Find her position relative to sea level when she took the photo.
Answer:
I believe the answer is -28
Step-by-step explanation
I gotchu bro
The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go

The slope of line r = 5 and the slope of line s = -5. Are the lines parallel, perpendicular or neither?
Answer:
Neither, if they are parallel they slope would be the same, and if they were perpendicular one of the slopes would be -1/5 so I am pretty sure it is neither. (I also graphed it and it didn't look perpendicular or parallel)

a force of 10 newtons act in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
A. 2.59 joules
B. 3.88 joules
C. 38.82 joules
D. 150.00 joules
Answer:
C
Step-by-step explanation:
i think
The required work done is 38.82 joules.
Work done to be determine for force of 10 newton on angle of 75° for 15 meters.
Work done is define as the force required to move an object by some displacement.
Here, work done = force x displacement x cosФ
= 10 x 15 x cos75°
= 150 x 0.25
= 38.82 joules
Thus, the required work done is 38.82 joules.
