Answer:
<h2>
<em><u>25 square inches </u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Parallel sides of the trapezium = 3in, 7in
Height of the trapezium = 5in
<em><u>Therefore</u></em><em><u>, </u></em>
Area of the trapezium



= 5in × 5in

<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Area</u></em><em><u> </u></em><em><u>if</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>trapezium</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>25</u></em><em><u> </u></em><em><u>square</u></em><em><u> </u></em><em><u>inches</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
The terms are 9, 4, 3b and 7a.
The terms are 9 – 4 and 3b + 7a.
The terms are 9, -4, 3b, and 7a.
Step-by-step explanation:
Answer:
175 means the city's population is 175 thousands in 2010.
Step-by-step explanation:
The model below gives the projection of the city's population , P, in thousands, with respect to time, t, in years, where 2010 corresponds to t=0.
The given equation is

We need to interpret 175 for the given model.
Substitute t=0 in the above equation.


At t=0 the value of P is 175 it means the city's population is 175 thousands in 2010.
A) Vectors are usually given in the form (x , y), therefore the x-component of v is 1.
B) Similarly to point A), the y-component of w is 6
C) the magnitude of the vector v+w is given by:
√[(x₁ + x₂)² + (y₁ + y₂)²] = √[(1 + (-2))² + (-3 + 6)²] = √(1 + 9) =√10
D) Compute -2 · v = (-2·1 , -2·(-3)) = (-2 , 6) = w
Therefore options B) and D) are true.
