Answer:
The height h of an object after t seconds is
h=-16t^2+48t+210h=−16t
2
+48t+210
The height of a neighboring 50-foot tall building is modeled by the equation h=50.
The time (t) when the object will be at the same height as the building is found to be t = –2 and t = 5.
To find:
The statement which describes the validity of these solutions.
Solution:
We have,
h=-16t^2+48t+210h=−16t
2
+48t+210
Here, t is the time in seconds.
For t=-2,
h=-16(2)^2+48(-2)+210h=−16(2)
2
+48(−2)+210
h=-64-96+210h=−64−96+210
h=50h=50
For t=5,
h=-16(5)^2+48(5)+210h=−16(5)
2
+48(5)+210
h=-400+240+210h=−400+240+210
h=50h=50
So, the value of h is 50 at t=-2 and t=5.
We know that time is always positive so it cannot be negative value. It means t=-2 is not possible.
The solution t = 5 is the only valid solution to this system since time cannot be negative.

how to find the measure of the obtuse angle
Answer:
Measure of obtuse angle is 134 degrees
Step-by-step explanation:
these two angles are supplementary so they add up to 180
68x-2 +23x=180
91x-2=180
91x = 182
x = 2
plug in x
68 (2) -2 = 134

find the value of x in the picture
Answer:
x = 9
Step-by-step explanation:
5x+4 = 49
subtract 4 from both sides
5x = 45
divide both sides by 5
x = 9
Answer:
x = 9
Step-by-step explanation:
49 degrees and (5x + 4) are vertical lines, meaning they are congruent.
We can make an equation with this information:
(5x + 4) = 49
-4 -4
5x = 45
/5 /5
x = 9

Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)
Answer:
a + (b + c) = (a + b) + c
Step-by-step explanation:
a= (-12), b = 4, c = (-25)
[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]
Answer:
GIVEN :-
a = -12b = 4c = -25TO VERIFY :-
a + (b + c) = (a + b) + cSOLUTION :-
Find the values of L.H.S. & R.H.S.
L.H.S. :-
Put all values in → [tex]\boxed{a+(b+c)}[/tex]
⇒ -12 + [4 + (-25)]
⇒ -12 + (4 - 25)
⇒ -12 + (-21)
⇒ -12 - 21
⇒ -33
R.H.S. :-
Put all values in → [tex]\boxed{(a+b)+c}[/tex]
⇒ (-12 + 4) + (-25)
⇒ -8 - 25
⇒ -33
CONCLUSION :-
L.H.S. = R.H.S.
⇒ a + (b + c) = (a + b) + c

Answer:
area = 82 cm²
Step-by-step explanation:
The figure comprises a trapezoid, a triangle and a square.
Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.
Area of square : (side)²
= (2)²
= 4 cm²
Area of triangle : ½ × b × h
= ½ × 3 × 12
= 3 × 6
= 18 cm²
Area of trapezoid : ½ × (a + b) × h
= ½ × (5+5) × 12
= ½ × 10 × 12
= 5 × 12
= 60 cm²
Now, area of the composite figure :
= 4 + 18 + 60
= 22 + 60
= 82 cm²
Answer:
82 cm²Step-by-step explanation:
If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.
Its area is:
A = (5 + 8)*12/2 = 78 cm²Add the area of the square with sides of 2 cm:
A = 2*2 = 4 cm²Total area is:
A = 78 + 4 = 82 cm²Gigi earned $65 for 5 hours of gardening. She earned $90 for 9 hours of office work. Which statement correctly compares Gigi’s earning per hour for gardening and office work?

What number should Rihanna use for the height of the parallelogram if she uses 28 inches for the base
Answer:
[tex]Height = 7in[/tex]
Step-by-step explanation:
Given
See attachment for parallelogram
[tex]Base = 28in[/tex]
Required
What is the height?
The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.
From the question, we have:
[tex]Base = 28in[/tex]
Also from the question, the difference between the two parallel sides is 7in.
Hence, the height of the parallelogram in 7in

what are the next two terms in the sequence?: 1, -2, 4, -8
Answer:
16 and -32Step-by-step explanation:
-2÷1 = -2
4÷(-2) = -2
-8:4 = -2
So this is a geometric sequence with a common ratio of -2
Therefore:
the 5th term: -8×(-2) = 16
the 6th term: 16×(-2) = -32
