The first term a1 is given to be -4. The formula for the next terms: an = an-1 + 7 means to add 7 to the previous term to get the next.
-4, 3, 10, 17, 24, 31
Answer A
Answer: B
Step-by-step explanation: The answer is B because it explains that H is the amount of hours. The last option doesn't have H included in the equation. Secondly. You want to find the total so you'll end up having an addition equation.
Therefore your answer is, c=45h + 95

Answer:
Step-by-step explanation:
Given is a graph of a parabola.
We have to find the equation of the paabola.
We observe from the graph the following points.
i) Vertex is (0,0)
ii) Open downward
iii) Axis of symmetry is y axis or x=0
iv) It passes through (1,4)
The parabola will be of the form
Substitute x=1 and y =4, to find a
1 = -4a(4)
a =
Hence equation would be
Answer:
0.6625
Step-by-step explanation:
To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,
Area of square is A=s*s=0.25*0.25=0.0625.
Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.
There are four equal triangles so together there area is 4*0.15 = 0.60.
Add the square to it and you have the surface area of the pyramid.
0.0625 + 0.60 = 0.6625
