derivation through first principle sin 2x?

Answer:

14 cups = 7 pints

144 cups = 36 quarts

Step-by-step explanation:

[tex](-8)*\frac{2}{3} = -\frac{16}{3}[/tex]

[tex](-8)*(-\frac{2}{3} ) = \frac{16}{3}[/tex]

[tex]-\frac{18}{3} = -6[/tex]

[tex]\frac{-18}{-3} = 6[/tex]

Answer:

Your welcome

Step-by-step explanation:

Answer for the question:

It is B.

Answer:

[tex]c = 5[/tex]

Step-by-step explanation:

Given

[tex]f(c) = M[/tex]

[tex]f(x) = x^2 - x + 1[/tex]

[tex]Interval: [1,8][/tex]

[tex]M = 21[/tex]

Required

Find c using Intermediate Value theorem

First, check if the value of M is within the given range:

[tex]f(x) = x^2 - x + 1[/tex]

[tex]f(1) = 1^2 - 1 + 1[/tex]

[tex]f(1) = 1[/tex]

[tex]f(x) = 8^2 - 8 + 1[/tex]

[tex]f(x) = 57[/tex]

[tex]1 \le M \le 57[/tex]

[tex]1 \le 21 \le 57[/tex]

M is within range.

Solving further:

We have:

[tex]f(c) = f(x) = M[/tex]

[tex]f(x) = 21[/tex]

Substitute 21 for f(x) in [tex]f(x) = x^2 - x + 1[/tex]

[tex]21 = x^2 - x + 1[/tex]

Express as quadratic function

[tex]x^2 - x + 1 - 21 = 0[/tex]

[tex]x^2 - x - 20 = 0[/tex]

Expand

[tex]x^2 + 4x - 5x - 20[/tex]

[tex]x(x+4)-5(x+4)=0[/tex]

[tex](x - 5)(x+4) = 0[/tex]

[tex]x - 5 = 0[/tex] or [tex]x + 4= 0[/tex]

[tex]x = 5[/tex] or [tex]x = -4[/tex]

The value of [tex]x = -4[/tex] is outside the [tex]Interval: [1,8][/tex]

So:

[tex]x = 5[/tex]

[tex]f(c) = f(x) = M[/tex]

[tex]f(c) = f(5) = 21[/tex]

By comparison:

[tex]c = 5[/tex]

Answer: 157 degrees

Step-by-step explanation: Since vertical angles have the same measure and we're given that the measure of angle x is 157 degrees, then we know that the measure of angle y is also 157 degrees.

Answer:Percent error=29%

Step-by-step explanation:

Percent error=(Estimated value-Actual value/ Actual value) × 100

Estimated value = amount of cookies Payton thought the mix could make = 36

Actual Value= Amount of cookies made= 28

Percent error= (36- 28)/ 28 x 100

=8/28 x 100

=0.2857 x 100

=28.57 rounded to 29%

Answer:

x = -1

Step-by-step explanation:

-3(x-1) + 9 = 15

-3x + 3 + 9 = 15

-3x = 3

x = -1

Answer:

The variable (x) is -1.

Step-by-step explanation:

use the distributive property

-3(x - 1) + 9 = 15

-3x + 3 + 9 = 15

-3x + 12 = 15

       -12    -12

-3x = 3

divide by -3

x = -1

Answer:

f(-5)=5

Step-by-step explanation:

the "-5" is telling us what to plug in for x. So, the new equation would be:

f(-5)= -(-5)^2-7(-5)-5

if we reduce, the expression would be

-25+35-5

our final answer would be 5.

Answer:

p + 10

Step-by-step explanation:

We have an expression

"10 more than the number p"

How will you write the phrase?

The expression "10 more than the number p" shows that whatever amount p is, the total will always be 10 more of value than p. Therefore some type of adding is supposed to be here. Since this unknown value of a number will always be 10 more than p, we can come up to assume that p will be added by 10.

p + 10
