The answer is 928cm. There are 5 sides. When you find the area of a triangle you multiply base times height then divide by two. But in this case there are two identical triangles so you don’t need to divide. 24x12=288. Then you find the area of the long sides. Multiple 25 and 10 and you get 250. There are two of those sides. Now the last thing to do is find the area of the bottom side. For that one you multiply 14 and 10 and get 140. Now you add all of that together and get 928cm.

The error occurs in step 3. By the product rule, we have

$\dfrac{\mathrm d}{\mathrm dx}(\sec x\times\cos x)=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x+\sec x\times\dfrac{\mathrm d}{\mathrm dx}(\cos x)$

$=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x\boxed{+\sec x\times(-\sin x)}$

$=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x\boxed{-\sec x\times\sin x}$

(i.e. there is a missing factor of $\sin x$ )

Then

$\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x-\sec x\times\sin x=0$

$\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x=\sec x\times\sin x$

$\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)=\dfrac{\sec x\times\sin x}{\cos x}$

$\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)=\sec x\times\tan x$

Erina has a bag that starts with 50 marbles in it: 10 green marbles and 40 purple marbles. She wants to increase the ratio of gr

oksian1 [2.3K]

Answer:

I. 3 green and 1 purple

II. 1 green and 3 purple

III. 3 green and 3 purple

All can be added

Step-by-step explanation:

Initial ratio is green : purple = 10 : 40

= 1 : 4

If we add more of green marbles and purple marbles to the initial one, there will definitely be an increase in the ratio

For instance,

I. 3 green and 1 purple

II. 1 green and 3 purple

III. 3 green and 3 purple

All of them will cause and increase in the ratio.

Mr. Holms used 4/5 of a carton of orange juice he used equal amount of the leftover juice for 2 servings what fraction of the wh

liq [111]

Answer:

Mr. Holms used 1/10 of the whole carton for each serving.

Step-by-step explanation:

Mr. Holms used 4/5 of the carton, which means he has 1/5 of the carton remaining from a whole carton and if he divides 1/5 among 2 servings he gets 1/5 divided by 2 is 1/10.

Check Your Answer: 4/5 divided among 2 servings would be 4/5+ 1/10 + 1/10 = 8/10 + 1/10 + 1/10 = 10/10 = 1 whole carton.

Can anyone tell me the formula for finding the surface area of a triangular prism?

BARSIC [14]

Answer:

$bh$

Step-by-step explanation:

multiply the base times height for the area of the triangles (bh)
add the three sides of the triangle (s1 + s2 + s3).
multiply the sum of the triangle sides by the height of the prism (H)
add the values together for the answer
make sure to include the appropriate unit of measurement (ft, in, cm, m, mm, etc.)

A furniture maker uses the specification 21.88< or = w

Mekhanik [1.2K]

Seems like your question is quite incomplete, I bet here is the missing part *<or = 22.12 for the width w in inches of a desk drawer.
According to the fact that abs(w-22) should be less than equal to 12, the answer should have a look like this : Iw - 22I < or = 0.12. I am pretty sure it will help you.
Next time check it carefully. Regards!
