Step-by-step explanation:
2.5 m = 250 cm
so, the scale factor is 1/250
that means the tennis court is in reality
10×250cm × 5.5×250cm = 2500 × 1375 = 3,437,500 cm²
1 m² = 100×100 = 10,000 cm²
so,
3,437,500 cm² = 343.75 m²
Use the property that angles sum up to 360 degrees.
Also use property that <M = <R and <A = <P.
That gives the following equation:
m<R + m<A + m<M + m<P = 360
6x+5 + 9x+25 + 6x+5 + 9x+25 = 360
30x + 60 = 360
x = 10
Answer:
x = 10
m<M = 6x+5 = 65 degrees
The answer will be neither the bus nor the trains were running today. (D)
Answer:
a
Step-by-step explanation:
The parent function f(x) = x^2 can be shifted 12 units to the right by moving its vertex 12 units to the right. The parent function has a vertex at (0,0) since . It will shift to (12,0) so . The only value of a which will make it 0 is 12. So the equation is
f(x) = (x-12)^2
