Answers
You need to find x (adjacent)
The angle measure: 28 degrees
With opposite and adjacent, use tangent
Tan(28) = 0.5317094317
Tan(28) = 16/x
x = 16/0.5317094317
x = 30.0916

Step-by-step explanation:
x+95 = 4x-10 ( alternate angles)
or, 4x -x = 95+10
or, 3x = 105
x= 35
x+95 = 35+95 = 130
130 + ABC = 180 ( linear pair)

Answers
Answer:
d1 = 192
d2 = 192
Step-by-step explanation:
step 1
From the imformation given, the distance is the same
so from the table
d1 = 64t
d2 = 48(7-t)
the distance is the same, it means
d1 = d2
therefore we can get the time(t) from here
64t = 48(7-t)
64t = 336 - 48t
collect like terms
64t+48t = 336
112t = 336
t = 336/112
t = 3
substitute t into d1 to get the distance
d1 = 64t
d1 = 64 × 3
d1 = 192
Note, d1 = d2
d2 = 192 too
Solve the simultaneous equations

Answers
2x + 7y = 15 ---> equation (2)
multiply equation (1) by 7
and multiply equation (2) by -2
21x + 14y = 98 equation (1)
-4x -14y = -30 equation (2)
21x -4x = 98 -30
17x = 68
x = 4
not by substitution in any equation by x = 4
3x + 2y = 14
3(4) + 2y = 14
12 + 2y = 14
2y = 14-12
2y = 2
y = 1

Answers
Answer:

Step-by-step explanation:
Answer:
x² + 10x + 25 = 0
Step-by-step explanation:
Given that x = - 5 is a root then (x + 5) is a factor
Since it is a double root then (x + 5)² so equation is
(x + 5)² = 0 ← expand factor using FOIL
x² + 10x + 25 = 0

7. Tom weighs 168.5 pounds. His 2-year- old son, Nicholas, weighs 33.7 pounds. How many times as much as Nicholas does Tom weigh?
Answers
Answer:
Tom weighs 5 times as much as Nicholas
Step-by-step explanation:
To find how many times as much as Nicholas Tom weighs, we will divide Tom's weight by Nicholas' weight. This is done as follows:
Tom's weight = 168.5 pounds
Nicholas' weight = 33.7 pounds
Dividing both weights = 168.5 ÷ 33.7 = 5
∴ Tom weighs 5 times as much as Nicholas

A ball is dropped from a height of 64 feet. Its height, in feet, can be modeled by the function h(t) = -16t2 + 64, where t is the time in seconds since the ball was dropped. A. After how many seconds will the ball hit the ground? B. What is a reasonable domain and range for this function?
Answers
Answer:
See solution below
Step-by-step explanation:
The ball will hit the ground at whrn t = 0
Given the height of the ball modeled by the expression
h(t) = -16t^2 + 64
0 = -16t^2 + 64
16t^2 = 64
t^2 = 64/16
t^2 = 4
t = 2sec
The ball will hit the ground 2secs after
The domain are the values of the input values t and this values start from 2 and greater. Hence the domain of the function is {2, ∞}
when t = 2
h (2) = -16(2)^2 + 64
h(2) = -64+64
h(2) = 0
Hence the range are the output values i.e the height.
The range are within the range {0, ∞}
