Answer:24

Step-by-step explanation:

a^2+b^2=c^2

c^2 has to be 26 because it is the hypotinuce. 10 could take the place of a^2 or b^2, it dose not matter.

a^2+10^2=26^2

a^2+100=676

subtract 100 from both sides

a^2=576

Answer:

a(5) = 1.080

a(10) =  0.393

a(20) =  0.122

Step-by-step explanation:

Take the derivative of velocity v(t) -> acceleration a(t)

v(t) -> a(t)

Quotient Rule: [tex]\frac{u*dv-du*v}{u^2}[/tex]

[tex]120*\frac{x}{5x+13}[/tex]

Make u= 5x+13 and v=x

[tex]120*\frac{x'*(5x+13)-x*(5x+13)'}{(5x+13)^2}\\\\120*\frac{1*(5x+13)-x*(5)}{(5x+13)^2}\\\\120*\frac{(5x+13)-5x}{(5x+13)^2}\\120*\frac{13}{(5x+13)^2} \\\\a(t)=\frac{1560}{(5x+13)^2}[/tex]

Now Subsitute your a(5) , a(10) , a(20). Also, round to 3 decimal place.

a(5) = 1.08033241 = 1.080

a(10) = 0.3930461073 = 0.393

a(20) = 0.122170826 = 0.122

Answer:

  (a) 1.080 ft/s²

  (b) 0.393 ft/s²

  (c) 0.122 ft/s²

Step-by-step explanation:

Acceleration is the derivative of velocity. You are being asked to differentiate the given function and evalutate the derivative at three different times. The function is a rational function, so the formula for the derivative of a ratio is applicable.

  (u/v)' = (vu' -uv')/v²

__

For the given velocity function, the accleration is ...

  v(t) = (120t)/(5t +13)

  a(t) = v'(t) = ((5t +13)(120) -(120t)(5))/(5t +13)² = 1560/(5t +13)²

At t=5, the acceleration is ...

  a(5) = 1560/(5·5 +13)² = 1560/1444 ≈ 1.080 . . . ft/s²

At t=10, the acceleration is ...

  a(10) = 1560/(5·10 +13)² = 1560/3969 ≈ 0.393 . . . ft/s²

At t=20, the acceleration is ...

  a(20) = 1560/(5·20 +13)² = 1560/12729 ≈ 0.122 . . . ft/s²

B) 77.5 square feet

Step-by-step explanation:

cut shape into rectangle and triangle

area of rectangle = x*y

area of rectangle = 5*13

area of rectangle = 65

area of triangle = (z-x)*(y-w)/2

area of triangle = 5*3/2

area of triangle = 7.5

Total area = 65 + 7.5

Total area = 77.5, B)

Answer:

The true statement is The function f(x)= tan(x) is an odd function because f(-x) = -f(x).

When x is substituted with -x, the odd functions are those that return their negative inverse. When f(-x) = -f(x), it follows that f(x) is an odd function (x). The trigonometric sine function, tangent function, cosecant function, etc. are a few examples of odd functions.

If f(x) = f(x), then the function is odd for all x. An odd function's graph will be symmetrical in all directions around the origin. Consider how unusual f(x) = x³ is. In other words, the function on one side of the x-axis is graphically symmetric about the origin or sign inverted with respect to the other side.

As, we know for the

even function: f(-x) = f(x)

odd function: f(-x)= -f(x)

and, using Trigonometry

tan x = sin x / cos x

Then,

f(-x) = sin (-x) / cos (-x)

      = -sin (x) / cos (x)

      = -tan (x)

      = -f(x)

Thus, tan (x) is an odd function.

Hence, the function f(x)= tan(x) is an odd function because f(-x) = -f(x).

Use the Midpoint Rule Kelly travels 12m/s more than Chris does during the first ten seconds.

The midpoint rule is the rule that follows the median of a set of values which is the middle value when the values are written in numerical order.

From the table above, the midpoint for the velocity of Chris car = 81, while the midpoint for the velocity of Kelly's car = 93

Therefore, the Kelly's car travelled 93-81 = 12 m/s farther than Chris does during the first ten seconds.

1 oz silver costs 16.08

1 oz  Gold costs 1195.80

Silver

16.08/1 = x / 5                Multiply both sides by 5

5*16.08 = 1*x            

80.4       =x

Gold

1195.80/1 = x/5

5 * 1195 = 1 * x

5979  = x

Answer

Difference = Cost of Gold - Cost of Silver

Difference = 5979 - 80.4

Step-by-step explanation:

use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

and therefore also

sin(A)/a = sin(B)/b = sin(C)/c

where the lines and corresponding angles are always opposite of each other.

and remember, the sum of all angles in a triangle is always 180°.

and sin(x) = sin(180-x).

so, we have

sin(32)/43 = sin(B)/53

sin(B) = 53×sin(32)/43 = 0.653156302...

B = 40.77999844...° ≈ 41°

C = 180 - 32 - 40.77999844... = 107.2200016...° ≈ 107°

43/sin(32) = c/sin(107.2200016...)

c = 43×sin(107.2200016...)/sin(32) = 77.507143... ft

≈ 78 ft

B' = 180 - B = 139.2200016...° ≈ 139°

C' = 180 - 32 - 139.2200016... = 8.779998438...° ≈ 9°

43/sin(32) = c'/sin(8.779998438...)

c' = 43×sin(8.779998438...)/sin(32) = 12.38595519... ft

To simulate the probability in a spinner divide the spinner into colors depending on the probability each color represents.

This word refers to the likelihood for an event to occur. Moreover, it is often expressed either as a fraction, a percentage, or a number.

In this case, each of the colors represents a probability:

Due to this, the best is to divide the spinner by colors and considering the percentanges of each color. For example 40% of the spinner should be red, while 15% should be orange.
