what is the value of A = sin10.sin50.sin70 ?

Answer:

19 square cm

Step-by-step explanation:

4 + 2.5 = 6.5

4 × 6.5 = 26

Since the shape is half of the product above, we're going to divide it by 2

26 ÷ 2 = 13

4 × 3 = 12

12 ÷ 2 = 6

Now to add them together

13 + 6 = 19

Answer:

14 units

Step-by-step explanation:

Area is l*w and since the length is known, solve for width

182/13=13w/13

w=14

Answer:

14 units

Step-by-step explanation:

Given, the area of rectangle = 182 square units

length = 13 units

width = ?

By using the formula to find the area of a rectangle, we have

area of rectangle = length * width

182 = 13 * width

182/13 = width

14 units = width

Answer:

(x + 1)(x + 3)eˣ

Step-by-step explanation:

Since f(x) = (x + 1)²eˣ

df(x)/dx = d[(x + 1)²eˣ]/dx

By the product rule, duv/dx = udv/dx + vdu/dx

where  u =  (x + 1)² and v = eˣ

So,  df(x)/dx = d[(x + 1)²eˣ]/dx

= (x + 1)²deˣ/dx + eˣd(x + 1)²/dx

= (x + 1)²eˣ + eˣd(x + 1)²/d(x + 1) × d(x + 1)/dx  (by the chain-rule dy/dx = dy/du × du/dx)

= (x + 1)²eˣ + eˣ[2(x + 1) × 1]

= (x + 1)²eˣ + 2eˣ(x + 1)

= (x + 1)eˣ(x + 1 + 2)

= (x + 1)eˣ(x + 3)

= (x + 1)(x + 3)eˣ

Answer:

After 74 minutes of driving, he still has 32.5 miles to his destination.

Step-by-step explanation:

A linear relationship can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know that a line passes through the points (x₁, y₁) and (x₂, y₂), then we can write the slope as:

a = (y₂ - y₁)/(x₂ - x₁)

Now let's go to the question.

We know that the distance to his destination is a linear function of his total driving time.

We know that he has 55 miles to his destination after 44 minutes of driving. We can write this as the point (44 min, 55mi)

We know that he has 41.5 miles to his destination after 62 minutes of driving, we can write this as (62 min, 41.5mi)

Then the slope of this equation will be:

a = (41.5mi - 55mi)/(62min - 44min) = -0.75 mi/min.

Then the linear equation is something like:

y = (-0.75 mi/min)*x + b

to find the value of b we can use the fact that this line passes through the point (44 min, 55mi)

This means that when x = 44 min, we must have y = 55mi

Then:

55mi = (-0.75 mi/min)*44min + b

55mi + (0.75 mi/min)*44min = b

88mi  =  b

Then the equation is:

y = (-0.75 mi/min)*x + 88mi

Now we want to know how many miles will he have to his destination after 74 minutes of driving, then we need to replace x by 74 min.

y = (-0.75 mi/min)*74min + 88mi

y = 32.5mi

After 74 minutes of driving, he still has 32.5 miles to his destination.

Answer:

y = -x + 2

Step-by-step explanation:

The desired equation must have the form y = mx + b.

Start with -2Y - 2X = -6 and solve for y:              y + x = 2

Now solve this result for y:  

y = -x + 2

Step-by-step explanation:

Answer:

1. r(x) = [q(x)]/[p(x)] is x ≠ 0

2. r(x) = p(x) * q(x) is All real numbers

3. r(x) = [1]/[p(x) + 16q(x)] is x ≠ -2

4. r(x) = [q(x)]/[p(x) + 2] is x ≠ -1

5. r(x) = [1]/[p(x) - q(x)] is x ≠ 1, 2

Answer:

Your answer is 8.06.

Step-by-step explanation:

Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:

a² + b² = c²

Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.

a is going to be your smallest leg, so in this case a = 4.

b is going to be your longest leg, so it is b = 7.

Now, you don't know what c yet is so you simply write it as:

4² + 7² = c²

Do the exponents.

16 + 49 = c²

Add.

65 = c²

Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.

√65 = √c2

Once you do that, you have your answer!

8.0622577483 = c

Now just simplify and you're done :)

8.06

Might sound hard now but you'll get the hang of it.

With 2x-4 given to you, you can substitute x (input) and solve with that input to get y (output).

Ex. 2(0)-4=-4, (0, -4)

     2(1)-4=-2, (1, -2)

     2(2)-4=0, (2, 0)
