124 + 110 = 234
All you have to do is add them together :)
Answer:
Step-by-step explanation:
it is maximum.
when leading coefficient of x² is negative,
It is downward parabola.
or
y=-2x²+10x+1
=-2(x²-5x+(-5/2)²-(-5/2)²)+1
=-2(x-5/2)²+2×25/4+1
=-2(x-5/2)²+25/2+1
=-2(x-5/2)²+27/2
maximum value of y is 27/2 and is attained at x=5/2
vertex is (5/2,27/2)
Answer:
160.
Step-by-step explanation:
Work out the innermost parentheses first:
{[9 x (7.3+10.7)} - 5} + [3 x (7.8 - 6.8)}
= {[9 x 18} - 5} + [3 x 1}
= {162 - 5} + 3
= 160.
Answer:
Step-by-step explanation:
PQ+P/Q-R
By finding the common multiple
We'd have Q has the L.C.M
Thus;
(PQ²+P-QR)/Q
Answer:
314.00+200.96+113.04+78.50+63.59+38.47+28.26+3.14+.79
