Answer:
<h2>The answer is 15cm</h2>
Step-by-step explanation:
Let b be the length of the second parallel side
Area of a trapezium is given by
where
h is the height
a and b are the parallel sides
From the question
Area = 230 cm²
height = 20cm
one of parallel side / a = 8 cm
Substitute the values into the above formula and solve for b
That's
Reduce the fraction with 2
That's
Expand the terms
That's
Divide both sides by 10
We have the final answer as
<h3>b = 15cm</h3>
Hope this helps you
131.88 or jus do radius times 2 so 21+ 21 = 42.
42 x pi(3.14) = 131.88
Answer: Arc CE measures 62 units
Step-by-step explanation: What we have in the question is a circle with two secants ABC and ADE. The two secants have been extended such that two arcs have been formed which are, major arc CE (that is, 4x - 10) and minor arc BD (that is 26).
When you have a circle with two intersecting secants, the angle x (that is angle CAE) is derived as half of the difference of the two intercepted arcs. That is;
Angle x = 1/2 [CE - BD)
Angle x = 1/2 [ (4x - 10) - 26]
Angle x = 1/2(4x - 36)
Cross multiply and we now have
2x = 4x - 36
Collect like terms and we now have
36 = 4x - 2x
36 = 2x
Divide both sides by 2
18 = x
Having calculated x as 18, where arc CE equals 4x - 10, then substitute for the value of x.
CE = 4(18) - 10
CE = 72 - 10
CE = 62
Answer:
Problem 10:
Input X: -2, -1, 0, 1, 2
Output Y: -2, 1, 2, 1, -2
Nonlinear, exponential because there's an exponent. Plug the X values in place of X and solve solution to get Y values. Then graph
Problem 11: Linear because there's no exponent
Answer:
12
Step-by-step explanation:
(x^16)^3/4
Apply the law of exponents where (a^b)^c = a^(bc).
x^(16*3/4)
Multiply.
x^(48/4)
Divide.
x^(12)
x is raised to the 12th power.
