The solution of the inequality is option B (1 + 7/10) ≥ b

We want to solve the inequality: 7/2  ≥ b + 9/5

To do so, we just need to isolate the variable b.

7/2 ≥ b + 9/5

Subtracting 9/5 in both sides we will get:

7/2 - 9/5 ≥ b

35/10 - 18/10 ≥ b

17/10 ≥ b

(1 + 7/10) ≥ b

The correct option is B

Answer:

if you get good grades then you will not get into a good college

Step-by-step explanation:

The error that Janice made is that she did not convert the improper fraction StartFraction 130 over 30 EndFraction to a mixed number correctly in her final answer.

The error that Janice made can be identified by analyzing her calculations. Let's examine each step she took:

Step 1: 10 and StartFraction 5 over 6 EndFraction divided by 1 and two-thirds

In this step, Janice correctly converted the mixed number to an improper fraction, which becomes 10 and StartFraction 5 over 6 EndFraction = StartFraction 65 over 6 EndFraction.

Step 2: StartFraction 65 over 6 EndFraction divided by five halves

In this step, Janice attempted to divide the fractions. However, she made an error by adding the numerators and denominators instead of multiplying. This is incorrect. The correct operation for dividing fractions is to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of five halves is two fifths.

Step 3: StartFraction 65 over 6 EndFraction times StartFraction 2 over 5 EndFraction

Here, Janice multiplied the fractions correctly. The product of these fractions is StartFraction 130 over 30 EndFraction.

Step 4: StartFraction 130 over 30 EndFraction = 4 and one-third

In this step, Janice attempted to convert the improper fraction to a mixed number. However, she made another error in her calculation. The fraction StartFraction 130 over 30 EndFraction is not equal to 4 and one-third. The correct conversion would yield 4 and two-sixths or 4 and one-third.

Therefore, the error that Janice made is that she did not convert the improper fraction StartFraction 130 over 30 EndFraction to a mixed number correctly in her final answer.

The equation of the sinusoid function is:

3 Sin πx + 2.

Let's analyze the given options to find the correct equation:

a. 3 Cos πx + 2:

This option is a cosine function with a vertical shift of 2, but it does not have the correct amplitude or period. Therefore, it is not the correct equation.

b. 3 Sin x: This option is a sine function with the correct amplitude, but it does not have the correct vertical shift or period. Therefore, it is not the correct equation.

c. 3 Sin πx + 2: This option is a sine function with the correct amplitude and vertical shift. Let's check if it has the correct period:

To determine if the period is correct, we need to calculate the x-values when the function repeats itself.

In this case, we need to find x-values such that sin(πx) = 0, since the function will reach its maximum and minimum points again at those x-values.

sin(πx) = 0 when πx = 0, π, 2π, 3π, ...

Solving for x, we have:

πx = 0 ⟹ x = 0

πx = π ⟹ x = 1

πx = 2π ⟹ x = 2

πx = 3π ⟹ x = 3

From this, we can see that the function repeats itself every integer value of x, which matches the given information.

Therefore, option (c) is the correct equation: 3 Sin πx + 2.

Option (d) 3 Cos x does not have the correct vertical shift or period, so it is not the correct equation.

Hence, the equation of the sinusoid function is:

3 Sin πx + 2.

The rule of (x, y) → (-x, y), which is reflection over y-axis.

Given that, ΔABC maps to triangle ΔA'B'C'.

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

The coordinate points of ΔABC are A(-4, 3), B(-3, -3) and C(1, 2) and the coordinate points of ΔA'B'C' are A'(4, 3), B'(3, -3) and C'(-1, 2).

Here, A(-4, 3) → A'(4, 3), x-coordinate is negated and y-coordinate remains same.

Similarly, B(-3, -3) → B'(3, -3) and C(1, 2) → C'(-1, 2) follows the same pattern.

From this, it is clear that the coordinates of triangle ABC is reflected on y-axis.

The simplified form of √([2m5z6]/[xy]) is (√2m√5z√6) / (√x√y).

To simplify the expression √([2m5z6]/[xy]), we can break it down step by step:

Simplify the numerator:

√(2m5z6) = √(2) * √(m) * √(5) * √(z) * √(6)

= √2m√5z√6

Simplify the denominator:

√(xy) = √(x) * √(y)

Combine the numerator and denominator:

√([2m5z6]/[xy]) = (√2m√5z√6) / (√x√y)

Thus, the simplified form of √([2m5z6]/[xy]) is (√2m√5z√6) / (√x√y).

f(x) = x + 8      if     (x + 8) ≥ 0

f(x) = -(x + 8)     if    (x + 8) < 0.

The liters of 80% material is 2/3 liters.

The liters of the 50% solution is 1/3 liters.

Based on the information, the scientist is working with two different concentrations of hydrochloric acid (HCI).

Let x = volume of 80%

Let 1 -x =volume of 50%

Therefore, the expression to illustrate the information will be:

80x + 50 × (1 - x) = 70

80x + 50 - 50x = 70

30x = 70 - 50

30x = 20

Divide

x = 20/30

x = 2/3

Therefore there are 2/3 liters of 80% material

The liters for the 50% solution will be 2/3 subtracted from 1. The 2/3 implies that for the 80% material. This will be:

= 1 - 2/3

= 1/3

There are also 1/3 liters of 50% material.

3x - 2x = 30 + 20

x = 50

That is the value of x.

The measure of length of the triangle is solved and

a) x = 4.9 units

b) x = 14 units

c) x = 4.8 cm

d) b = 68.5 units

Given data ,

Let the triangle be represented as ΔABC

where the measure of the lengths of the sides are given as

a)

The measure of hypotenuse AC = 12

The measure of angle ∠BAC = 66°

So , from the trigonometric relations , we get

cos θ = adjacent / hypotenuse

cos 66° = x / 12

So , x = 12 cos ( 66 )°

x = 4.9 units

b)

The measure of base of triangle BC = 20 units

And , the angle ∠BAC = 55°

So , from the trigonometric relations , we get

tan θ = opposite / adjacent

tan 55° = 20/x

x = 20 / tan55°

x = 14 units

c)

The measure of base of triangle BC = 4 cm

And , the angle ∠BAC = 57°

So , from the trigonometric relations , we get

sin θ = opposite / hypotenuse

sin 57° = 4/x

x = 4 / sin 57°

x = 4.8 cm

d)

The measure of base of triangle BC = 38 units

And , the angle ∠BAC = 61°

So , from the trigonometric relations , we get

tan θ = opposite / adjacent

tan 61° = b/38

b = 38 x tan 61°

b = 68.5 units
