You do £68.85 - £15.30= (the answer)
Then you do the answer of that divided by 0.85
Answer:
This tells us that the vertex is at (−2, 9) and the equation of the axis of symmetry is x = −2. To find the x-intercepts, we put y = 0 to obtain
(x + 2)2 − 9 = 0
(x + 2)2 = 9
x + 2 = 3 or x + 2 = −3
x = 1 or x = −5.
Step-by-step explanation:
Image result for Which quadratic function has a y-intercept of 4? y=x2−2x+4 y=x2+2x+9 y=−x2+3x y=x2+13x+12
The standard form of a quadratic equation is written as y=ax2+bx+c, where x and y are variables and a, b, and c are known constants. To find the y-intercept from a quadratic equation, substitute 0 as the value for x and solve. The y-intercept is always equal to the value of c in the equation.
Answer:
1:05 p.m
Step-by-step explanation:
they took 35 minutes...... and they arrived at 1:40 p.m so 40-35= 5 = 1:05 p.m :)
Answer:
Option A) 2.5
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 46
Sample mean, 
= 50
Sample size, n = 25
Alpha, α = 0.05
Population standard deviation, σ = 8
First, we design the null and the alternate hypothesis
Formula:
Putting all the values, we have
Option A) 2.5
