Answer:
This is the distributive property
Step-by-step explanation:
You use the distributive property to allocate a number outside of the parentheses to inside the parentheses.
For this example, they distributed a to both b and c making it a*b + a*c
This will result in the same answer:
3/5(-2 + 10/13) = 3/5*-2 + 3/5*10/13
3/5(-1.23..) = -6/5 + 30/65 (..= approx)
approximately- 0.74 = -0.74
Answer:
1.
2.
3.
Step-by-step explanation:
Write in exponential form
Using the law of logarithm which says if
then
By comparison;
A = 16; b = 2 and x = 4
The expression becomes
Write in exponential form
Applying the same law as used in (1) above;
A = 2; b = 16 and
The expression becomes
Write in logarithm form
Using the law of logarithm which says if
then
By comparison;
b = 2; x = z and A = y
The expression becomes
The criteria to find out the x-intercept of the line is we find out the result when
y = 0
- 2x + 5y = -20
- 2x + 0 = -20
x = -20 / -2
x = 10

Answer:
D cos(N)
Step-by-step explanation:
In case you haven't remembered the fact that the sine of an angle is equal to the cosine of its complement (the other acute angle in a right triangle), you can always go back to the definitions.
Sin = Opposite/Hypotenuse
sin(L) = NM/NL
and
Cos = Adjacent/Hypotenuse
cos(N) = NM/NL = sin(L)
The equivalent of sin(L) is cos(N).
Answer:
C
Step-by-step explanation:
The central angle is equal to the arc that subtends it, that is 54°
area of sector = area of circle × fraction of circle
A = πr² ×
= π × 10² ×
= 100π × ( cancel 20 and 100 )
= 5π × 3
= 15π cm² → C
