Answer:  The number of solutions to the equation sin (2000x) = 3/7 in the interval [0,2π] is (A) ... 1 answer A sinusoid with amplitude 4 has a minimum value of 5.

1 answer

Step-by-step explanation: : You always have sin2(x)+cos2(x)=1. Now how do sin2(x)+cos2(x) and sin2000(x)+cos2000(x) relate if (sin(x),cos(x))≠(±1,0) and (sin(x),cos(x))≠(0,±1)?

Answer:

The equation has an Inifinite amount of solutions

Step-by-step explanation:

2 ( 3g + 2 ) = 1/2 ( 12g + 8 )

First use the distributive property of multiplication -

6g + 4 = 6g + 4

6g cancels out from both sides of the equation -

4 = 4

When both sides of an equation are the same there is an infinite amount of solutions.

Answer:

x = 5

Step-by-step explanation:

4x-3=2x+7

Subtract 2x from each side

4x-2x-3=2x-2x+7

2x-3 = 7

Add 3 to each side

2x-3+3 = 7+3

2x = 10

Divide by 2

2x/2 = 10/2

x = 5

Answer:

f=39

Step-by-step explanation:

hi! first, we can multiply by 12 on both sides to eliminate the 12 in the denominator.

f+3= (7/2)*12

f+3=84/2

f+3=42

now, subtract 3 on both sides.

f=39

Given:

Number of rows = 3

Number of columns = 6

Number of square boxes = 18

yellow square boxes in the top two rows = 12

Blue square boxes in the first 5 columns = 15

Number of green boxes (shading overlaps) = 10

To find:

The model to show multiplying a fraction by a fraction.

Solution:

2 rows out of 3 are shaded yellow.

Fraction for yellow = [tex]\dfrac{2}{3}[/tex]

5 columns out of 6 are shaded blue.

Faction for blue = [tex]\dfrac{5}{6}[/tex]

10 out of 18 squares are green.

Faction for green =  [tex]\dfrac{10}{18}=\dfrac{5}{9}[/tex]

Now,

[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}[/tex]

[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}[/tex]

Therefore, the correct option is D.

The correct option is D.

2 rows out of 3 are shaded yellow.

Fraction should be [tex]2\div 3[/tex]

Now

5 columns out of 6 are shaded blue.

Fraction should be [tex]5 \div 6[/tex]

And,

10 out of 18 squares are green.

Fraction should be  [tex]10 \div 18 = 5\div 9[/tex]

Now

[tex]\frac{2}{3} \times \frac{5}{6} = \frac{10}{18}\\\\ \frac{2}{3} \times \frac{5}{6} = \frac{5}{9}[/tex]

Answer:

y = ✔ 1x+ ✔ -3

Step-by-step explanation:

The equation of the line passing through the points (2, -1) and (10, 7) is y =  x - 3.

The point slope form of a line is given by -

y - y₁ = m(x - x₁)

Given is a line that passes through the points (2, -1) and (10, 7).

The point - slope form of a line is given by the general equation -

y - y₁ = m(x - x₁)

We will find the slope of the line as follows -

m = (7 + 1)/(10 - 2) = 8/8 = 1

The line passes through the point (2, -1), so we can write the equation of line as -

y - (- 1) = x - 2

y + 1 = x - 2

x - y = 3

y =  x - 3

Therefore, the equation of the line passing through the points (2, -1) and (10, 7) is y =  x - 3.

Answer: 10

Step-by-step explanation:

The x-intercepts means when y equals 0, or when the function crosses the x-axis.

0 = (x-6)^2 - 16

16 = (x-6)^2

Take the square root of both sides:

4 = (x-6)

Add 6 to both sides to get:

x = 10

Answer:

Step-by-step explanation:

T=L(8+RS)

T=L8+LRS

T-L8=LRS

R=T-L8/LS

The required solution to the given equation is R = (T - 8L)/LS.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

T = L(8 + RS)

Apply the distributive property of multiplication,

T = L × 8 + L × RS

T = 8L + LRS

Rearrange the terms in the above equation,

T - 8L = LRS

Divided by LS into both sides, and we get

R = (T - 8L)/LS

Thus, the required solution to the given equation is R = (T - 8L)/LS.
