Answer:
u = 12
Step-by-step explanation:
formula : (base x height) / 2
60 x 2= 120
120 / 10 = 12
Answer: the answer is 3
Step-by-step explanation: The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point If y = x 3 then d y d x = 3 x 2 When x = 1 ⇒ d y d x = 3 So the slope equals 3
Answer:
32
Step-by-step explanation:
even numbers are 2,4,6,...,78
it is an A.P.
first term a=2
c.d. d=4-2=2
an=a+(n-1)d
78=2+(n-1)2
76=(n-1)2
n-1=76/2=38
n=38+1=39
now we take multiples of 10
10,20,30,...,70
70=10+(n-1)10
60=(n-1)10
n-1=60/10=6
n=6+1=7
so reqd. number of numbers=39-7=32
Answer:
5 and 7
Step-by-step explanation:
5 and 7 are vertical angles. The others are supplementary
Answer:
4
Step-by-step explanation:
8(-1)^4 - 3(-1) - 7
= 8(1)+3-7
=8+3-7
=4
