Answer:
The x coordinate is 2
Step-by-step explanation:
Given


Required
Determine the x coordinate of B
Since B is the bisector of AC, then B is the midpoint and will be calculated using;

Considering the x coordinates alone;

Where
and 
Substitute values for x1 and x2



<em>Hence;</em>
<em>The x coordinate is 2</em>
Answer: x = 4
Step-by-step explanation:
5x + 34 = -2(1 - 7x)
5x + 34 = -2 + 14x Multiply -2 to 1 and -7x
5x + 36 = 14x Add 2 to both sides
36 = 9x Subtract 5x to both sides
4 = x Divide 9 to both sides
Answer:
The arrow is at a height of 48 ft after approximately <u>0.55</u> s and after <u>5.45</u> s
Step-by-step explanation:
The following information is missing:
<em>The height of an arrow shot upward can be given by the formula s = v0*t - 16*t², where v0 is the initial velocity and t is time.How long does it take for the arrow to reach a height of 48 ft if it has an initial velocity of 96 ft/s? </em>
If the arrow is at a height of 48 ft and its initial velocity is 96 ft/s, then:
48 = 96*t - 16*t²
16*t² - 96*t + 48 = 0
16*(t² - 6*t + 3) = 0
t² - 6*t + 3 = 0
t² - 6*t + 3 + 6 = 0 + 6
t² - 6*t + 9 = 6
(t - 3)² = 6
t - 3 = √6
t - 3 = 2.45; t = 2.45 + 3; t = 5.45
or
t - 3 = -2.45; t = -2.45 + 3; t = 0.55
Answer:
2^3 = 8
base = 2, main number in the exponential equation
exponent = 3, have to multiply the base 3 times by itself
power = 2^3, the whole equation
