Step-by-step explanation:
4a.
the circumference of a circle is
2×pi×r
we know, r = 6 cm.
so the whole circumference is
2×pi×6 = 12×pi = 37.69911184... cm
4b.
the arc BC is the part of the full circumference that corresponds to 120° out of the 360° of a full circle.
the arc BC is then
12×pi × 120/360 = 12×p × 1/3 = 4×pi = 12.56637061... cm
the perimeter of the shaded area (pie slice) is the arc BC plus 2 radius lengths (from the arc points to the center of the circle)
12.56637061... + 2×6 = 12.56637061... + 12 =
= 24.56637061... cm
4c.
the area of a circle is
pi×r²
in our case
pi×6² = 36pi = 113.0973355... cm²
the area of the shaded area (pie slice) is the 120° part of the full 360° circle area :
36pi × 120/360 = 36pi × 1/3 = 12pi = 37.69911184... cm²
if f(x)=-3x-5 and g(x)=4x-2 find (f-g) (x)
If f(x)=-3x-5 and g(x)=4x-2, then the value of (f-g)(x) is -7x-3.
The given functions are f(x)=-3x-5 and g(x)=4x-2.
We need to find the value of (f-g)(x)
What is a function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Now, (f-g)(x)=f(x)-g(x)=(-3x-5)-(4x-2)
= -3x-5-4x+2 = (-3x-4x)+(-5 + 2)
= -7x-3
Therefore, the value of (f-g) (x) is -7x-3.

f(z)=(1/3)
h(z) = z+4/z-2
evaluate (h•f)(0)
The value of the composite function (h•f)(0) is -2/3
How to solve the composite function?The functions are given as:
f(z)=(1/3)
h(z) = z+4/z-2
Start by calculating f(0) and h(0)
f(0) = 1/3
h(0) = (0+4)/(0-2)
h(0) = -2
The composite function is then calculated as:
(h•f)(0) = h(0) * f(0)
This gives
(h•f)(0) = -2 * 1/3
Evaluate
(h•f)(0) = -2/3
Hence, the value of the composite function (h•f)(0) is -2/3

Answer:
16 + 9 = 25
Step-by-step explanation:
For each term in the sequence, we can see that the second number being added increases by 2 each time (3, 5, 7)
And that the first number of each term increases by the value of the second term
(1 increases by 3; 4 increases by 5)
we can follow out these two observations to find T4
the first term (9) will increase by the value of the second term (7)
{the sum of the previous term is the first number}
so the first number of T4 will be 16.
Because we left off on +7, we are now on +9
so, T4 is
16 + 9 {and then do the math accordingly}
16 + 9 = 25
So, T4 is
16 + 9 = 25

PLEASE HELP
Answer:
Using the concepts of Number System, we find that the sum of the largest and the smallest of the given four numbers is 4.29.
Step-by-step explanation:
The given set of numbers is 3.09, 3.9, 0.39 and 0.399.
The given numbers are related to each other as:
3.9 > 3.09 > 0.399 > 0.39
3.9 is greater than 3.09 as
3.9 > 3.09
3 + 0.9 > 3 + 0.09
0.9 > 0.09
90 > 9
0.399 is greater than 0.39 as
0.399 > 0.39
399 > 390

What is the principal, if a person paid an amount of $432 after 1 year at 8% rate of interest per annum
Answer:
principal = $400
Step-by-step explanation:
amount(a)=principal(p) + interest(y).........(1)
Interest(y)=principal(p) x rate(r) x time(t)....(2)
In (1), p= a - y...........(3)
putting (3) in (2),
y = (a - y) x r% x t
y = (432 - y) x 8% x 1
y = 3456%-8y%
y + 0.08y = 3456%
1.08y = 34.56
y = 32
but a - y = p
432 - 32 = p
p = 400
principal = $400

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
3x° + 3x° + y° = 180° (Supplementary angle)
6x° + y° = 180° .....1

25%
Step-by-step explanation:
when we count, we know that there are 8 possible outcomes as to where the spinner will land.
{the following will be assuming each section has an equal chance of being landed on; that the spinner is not weighted}
We know that two of these 8 possibilities are "A"
This means that A has a 2/8 chance of being landed on
we can simplify 2/8 to 1/4; because they are equivalent ratios/fractions
to calculate percentage, we can follow through with our equation of 1/4
[divide 1 by 4]
1 / 4 = 0.25
