Value of x is 1/5
Step-by-step explanation:
- Step 1: Given equation is 4 = √6x + 15 - x. Square both sides of the equation.
⇒ 16 = 6x + 15 - x
⇒ 16 = 5x + 15
⇒ 1 = 5x
∴ x = 1/5
Answer:
(t, h(t)) = (4, 9256)
Step-by-step explanation:
We assume you intend the h(t) function to be ...
h(t) = -16t^2 +128t +9000
The equation can be written in vertex form as follows:
h(t) = -16(t^2 -8t) +9000
h(t) = -16(t^2 -8t +16) +9000 -(-16)(16) . . . . add and subtract -16(16) to complete the square
h(t) = -16(t -4)^2 +9256 . . . . . vertex form of the height function
The vertex of h(t) is (4, 9256), an altitude of 9256 feet after 4 seconds.
Answer:
B
Step-by-step explanation:
14x - 3x + 11 = -22
-11 -11
14x - 3x = -33
11x = -33
/11 /11
x = -3
The product of the ___means___ equals the products of the ___extremes___
For example:
3/6 = 4/8
Cross multiplying we get
3*8 = 6*4
24 = 24
The "means" are the middle values 6 and 4. The extremes are the outer edge values 3 and 8
The sum of the measures of angles in the polygon with n angles is
180°(n - 2)
We have an octagon → n = 8.
The sum of the measures of angles in an octagon is
180°(8 - 2) = 180°(6) = 1080°
The equation:
x + 139 + 140 + 125 + 116 + 152 + 2x + 143 = 1080
3x + 815 = 1080 <em>subtract 815 from both sides</em>
3x = 265 <em>divide both sides by 3</em>
<h3>x = 88 1/3</h3>
