Answer:
0.88m²
Step-by-step explanation:
Area of a trapezium = 1/2(a+b)h
a and b are the parallel sides
h is the height
Given
a = 1m
b = 1.2m
h = 0.8m
Substitute
Area of the trapezium = 1/2(1+1.2)(0.8)
Area of the trapezium = 1/2(2.2)(0.8)
Area of the trapezium = 1.1 * 0.8
Area of the trapezium = 0.88m²

Answer:
1.05 × 1.05 × 1.05 × 1.05 × 1.05 = 1.2762815625
Step-by-step explanation:
An exponent indicates how many times the base is a factor in the product. That is, 1.05 to the 5th power means ...
1.05⁵ = 1.05 × 1.05 × 1.05 × 1.05 × 1.05
This multiplication expression is evaluated in the usual way.
= 1.1025 × 1.05 × 1.05 × 1.05
= 1.157625 × 1.05 × 1.05
= 1.21550625 × 1.05
= 1.2762815625

All scientific and graphing calculators have a button for computing the power of a number. On my calculator its label is
. The particulars of the function of this button can be found in the manual for your calculator.
For on-line calculators, such as the go.ogle calculator, or the Desmos graphing calculator, the caret (^) is used to signify an exponent. (See the input line in the first attachment for an example.)
The correct way of getting this answer with proof of simplifying the top to the multiplied amount and then subtracts that then simplify to double check
Answer:
B= 21° C= 29°
Step-by-step explanation:
Use sin rule.
1st one.
sin44°/33 = sinB/17
sinB= 17sin44/33
B= sin^-1 ( ans)
B= 20,97 =21°
2nd one.
sin92°/35 = sinC/17
sinC = 17sin92°/35
C= sin^-1 (ans)
C= 29,04° = 29°
