1 answer:

3 0

C is same thing as 1c

1c + 1/4c

(In simple words: Adding a whole to 1/4.)
1 + 1/4 = 1 1/4 or 5/4
same thing when having c:
1c + 1/4c = 1 1/4c or 5/4 c

Answer: 1 1/4c or 5/4c

Solve for q. s = 4p + 4q solve the equation

Harlamova29_29 [7]

Answer:

$q = \frac{s -4p}{4}\\$

Step-by-step explanation:

$s = 4p +4q \\ 4p +4q = s \\ 4p +4q -4p = s -4p \\ 4q = s - 4p \\ \frac{4q}{4} = \frac{s -4p}{4} \\ q = \frac{s -4p}{4}$

If we have the equation y=ax2+bx+c, how can we can find the x-coordinate of the vertex?

pishuonlain [190]

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.

Evaluate the surface integral. s xy ds s is the triangular region with vertices (1, 0, 0), (0, 8, 0), (0, 0, 8)

zmey [24]

Parameterize $S$ by

$\vec s(u,v)=(1-u)v\,\vec\imath+8uv\,\vec\jmath+8(1-v)\,\vec k$

with $0\le u\le1$ and $0\le v\le1$ .

Then the surface element is

$\mathrm dS=\|\vec s_u\times\vec s_v\|\,\mathrm du\,\mathrm dv=8\sqrt{66}\,v\,\mathrm du\,\mathrm dv$

and the surface integral is

$\displaystyle\iint_Sxy\,\mathrm dS=8\sqrt{66}\int_0^1\int_0^18(1-u)uv^3\,\mathrm du\,\mathrm dv=\boxed{8\sqrt{\dfrac{22}3}}$

What is the area of ΔABC? Round to the nearest tenth of a square unit.

kramer

Answer:
8.4 square units

Explanation:
The area of the triangle can be calculated using two sides and an included angle as follows:
area = 0.5 * 1st side * 2nd side * sin(angle included between them)
............> This is shown in the attached image

In the given triangle, we have:
the two sides 2*√2 and 6 units
the angle included between them is 80°

Therefore, we can apply the above rule to get the area as follows:
area = 0.5 * 2√2 *6* sin(80°)
area = 8.35 which is approximately 8.4 square units

Hope this helps :)
