Answer:
to start of in math you use stuff like numbers and equations although you can use equations in science in science you use different types of technology for that.
The height of the telephone pole = 9 / 1.5 = 6 meters
Answer:
the answer is D
Step-by-step explanation:
times 26 by 30 then times the product by 4 since a trinaglar pyramid has four sides
Using the discriminant from the quadratic formula (√b²-4ac) since that is the only way to get a solution to not be real (b²-4ac has to be negative), we get
m²-4*3*7=m²-84. Solving for m if m²-84=0, m²=84 and m=+-√84. Therefore, if m is positive, the highest possible value of m is √84. However, we have to find the integer value - with a bit of guess and check, we find that 9²=81 and is the integer you get by rounding down √84 (if we rounded up, 10 would have real solutions since we need the square to be less than 84 to get m²-84 negative). Therefore, 9 is our answer
