Please Help!! If Y = Sin X, Then Dy/dx =

Answers

Answer 1

Answer:

the answer is option B

Step-by-step explanation:

To find dy/dx the equation here is

first multipled by derivative of second + second multipled by derivative of first

y = x*sinx

dy/dx = x * derivative of sinx + sinx * derivative of x

derivative of x with respect to x is 1

derivative of sinx with respect to x is cosx

therefore

dy/dx = x * cosx + sinx * 1

= x * cosx + sinx

Need help finding the missing side of each triangle?

Answers

This is a right triangle. Use the Pythagorean theorem to solve:

x^2 + 5.8^2 = 15.6^2

x^2 + 33.64 = 243.36

Subtract 33.64 from both sides:

x^2 = 209.72

Take the square root of both sides:

x = 14.48171

Round to 1 decimal place:

x = 14.5 in.

Answer:

x = 14.5 in

Step-by-step explanation:

There is something called pythagoras' theorem. It states that

a^2 + b^2 = c^2,

a, b and c being sides of a right-angled triangle.

C is always the hypotenuse and a and b are any of the other two.

(The hypotenuse is always the longest side, and always opposite to the right angle, which is always the biggest angle of a right-angled triangle.)

So here we know two sides, the hypotenuse and another side. Let's substitute them into the formula:

5.8^2 + x^2 = 15.6^2

x^2 = 15.6^2 - 5.8^2

x^2 = 243.36 - 33.64

x^2 = 209.72

x = sqr209.72

x = 7sqr107/5 = 14.48171261 in

= 14.5 in (if rounded to 3 significant figures)

You could use a shortcut to do all this and find the answer more quickly:

a^2 = c^2 - b^2 or b^2 = c^2 - a^2

also:

a = sqr(c^2 - b^2)

x = Sqr(15.6^2 - 5.8^2)

= 14.5 in

B. Sketch the reflection on the coordinate plane.

Answers

Answer:

A' = (-1, 6)

B' = (-2, 1).

C' = (-5, 2).

Step-by-step explanation:

Reflection  over the y-axis--->  (a, b) transforms to (-a, b).

So  A (1, 6) --->   A' (-1, 6).

The coordinates will have the same y-value but all x-values will become negative. So for example if A is (3,0), A’ would be (-3,0) and so on for B’ and C’

what is the rate of change for the numbers 3,5,7,9

Answers

Answer:

Plus 2 (+2)

Step-by-step explanation:

The rate of change is always a constant change from the given first term to the next one. In this case, you are adding 2 each time:

3 + 2 = 5

5 + 2 = 7

7 + 2 = 9

etc.

~

Change means difference in the state or condition of a thing and here the thing is number. The change made within them must be following some certain rules or patterns.

They can be uniform and here it is uniform for sure. The terms are increasing by 2 or we can say that for getting th next number, we need to add 2 with the previous.

3 + 2 = 55 + 2 = 77 + 2 = 9

So, the rate of change for the above numbers or number series is +2 or addition of 2[tex].[/tex]

A person invests 7000 dollars in a bank. The bank pays 5.5% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 13200 dollars?

Answers

The number of years it will take the person to leave the money in the bank until it reaches 13200 dollars is 2.9 years.

To calculate the time the person must leave the money in the bank until the money reaches 13200 dollars, we use the formula of compound interest below.

What is compound interest?

This is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

Formula:

A = P(1 + r/100)ⁿ................ Equation 1

Where:

A = AmountP = Principler = Raten = Time.

From the question,

Given:

P = 7000 dollarsr = 5.5%  componded monthlyA = 13200 dollars

Substitute these values into equation 1 and solve for n

13200 = 7000(1+(5.5×12)/100)ⁿ(1+(5.5×12)/100)ⁿ = 13200/7000(  1.66)ⁿ = 1.886n = 2.9 years

Hence, The number of years it will take the person to leave the money in the bank until it reaches 13200 dollars is 2.9 years.

[tex]2a^{\frac{-1}{-2} }[/tex]

Answers

Step-by-step explanation:

First of all, [tex]\frac{-1}{-2}[/tex] is equal to [tex]\frac{1}{2}[/tex] because a negative divided by a negative is positive. So now we've got [tex]2a^\frac{1}{2}[/tex]. Well, a fractional exponent, when simplified, is a root. For example, [tex]x^\frac{1}{3}[/tex] is equal to [tex]\sqrt[3]{x}[/tex], and [tex]x^\frac{2}{5}[/tex] is equal to [tex]\sqrt[5]{x^2}[/tex].

Now this is where people make mistakes. Remember, [tex]2a^\frac{1}{2}[/tex] is really [tex]2*a^\frac{1}{2}[/tex], which means only a is raised to the exponent. We would only raise 2a to the power of [tex]\frac{1}{2}[/tex] if our term was [tex](2a)^\frac{1}{2}[/tex]. But since our term is [tex]2*a^\frac{1}{2}[/tex] we raise a to the power of [tex]\frac{1}{2}[/tex] which is the same as [tex]\sqrt[2]{a}[/tex] or just [tex]\sqrt{a}[/tex]. Then we multiply that result by 2 and we have [tex]2\sqrt{a}[/tex] which is fully simplified.

The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

[tex]\rm y = a \ e^{bx}\\[/tex]

From the graph, at x = 0, the value of the function is 4. Then we have

[tex]\rm \\4= a \ e^{b\times 0}\\[/tex]

a = 4

Then the exponential equation is given as,

[tex]\rm y = 4e^{bx}[/tex]

From the graph, at x = 1, the value of the function is 2.426. Then we have

[tex]\rm 2.426 = 4 e ^b \\\\e^b = 0.6065[/tex]

Take natural log on both sides, then we have

b lne = ln 0.6065

b = - 0.50

Then the exponential equation is given as,

[tex]\rm y = 4 \ e^{-0.50x}[/tex]

The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.

Answers

Answer: 28

Step-by-step explanation:

Given: First group received 28 baseball cards and second group received 84 baseball cards.

Total cards= 28+84 =112

If each person entering the stadium received the same number , the  greatest number of baseballs cards they could have received = G.C.D. (28,84,112)

[G.C.D. = greatest common divisor]

Since the prime factorization of 28 , 84 and 112 are as follows

28 = 2 x 2 x7

84 = 2 x 2 x 3 x 7

112 = 2 x 2 x 2 x 2 x 7

G.C.D (28, 84, 112 )= 2 x 2 x7 = 28

The greatest number of baseballs cards they could have received = 28
