What is the area of this Trapezoid with heghit 13 units

Mathematics
1 answer:
Dimas [21]3 years ago
8 0
Trapezoid area = <span>((sum of the bases) ÷ 2) • height
</span><span>Trapezoid area = [(7 + 15 + 7) + (15)] /2 * 13
</span><span>Trapezoid area = (44 / 2) * 13
</span><span>Trapezoid area = 22*13
</span><span>Trapezoid area = 286

Double Check:
Area of both triangles = 7*13 = 91
Rectangle Area = 13*15 = 195
TOTAL AREA = 286
Correct!!!

The family of solutions to the differential equation y ′ = −4xy3 is y = 1 √ C + 4x2 . Find the solution that satisfies the initi
slega [8]

Answer:

The correct option is 4

Step-by-step explanation:

The solution is given as

y(x)=\frac{1}{\sqrt{C+4x^2}}

Now for the initial condition the value of C is calculated as

y(x)=\frac{1}{\sqrt{C+4x^2}}\\y(-2)=\frac{1}{\sqrt{C+4(-2)^2}}\\4=\frac{1}{\sqrt{C+4(4)}}\\4=\frac{1}{\sqrt{C+16}}\\16=\frac{1}{C+16}\\C+16=\frac{1}{16}\\C=\frac{1}{16}-16

So the solution is given as

y(x)=\frac{1}{\sqrt{C+4x^2}}\\y(x)=\frac{1}{\sqrt{\frac{1}{16}-16+4x^2}}

Simplifying the equation as

y(x)=\frac{1}{\sqrt{\frac{1}{16}-16+4x^2}}\\y(x)=\frac{1}{\sqrt{\frac{1-256+64x^2}{16}}}\\y(x)=\frac{\sqrt{16}}{\sqrt{{1-256+64x^2}}}\\y(x)=\frac{4}{\sqrt{{1+64(x^2-4)}}}

So the correct option is 4

Help please like hurry!!
adelina 88 [10]
The answer is a 36
This is because if you take the area of one of the three triangles that make up the trapezoid you do 1/2 base times height and get 12 and you add all three together thus getting 36 square inches
