Ymorist [56]3 years ago

Answer:

The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Dvinal [7]
The amount of energy that the given amount of food contains is the product of the given content per grams and the amount of food in grams. 

For this item, we assume that g(x) is the total energy that the howler monkey needs to obtain and x is the amount of food in grams. From the presented concept in the first paragraph,

amount of energy = (3.35 kcal/gram) x (amount of food)

8. What is the distance around the clock?
Elan Coil [88]

Answer:

The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

The diagonal of a square has length 10√2. Find the area of the square.
alex41 [277]

Answer: A = 100 square unit

Step-by-step explanation:

The formula for calculating the area of a square when the diagonal is given is :

Area = d^{2} / 2

That is :

A = \frac{(10\sqrt{2})^{2}}{2}

A = \frac{100(2)}{2}

A = 100 square unit
