1) Maeve needs to earn $140 each weekend to get at least $1,250, using a linear inequality.

2) The graph on a number line that solves her problem is number line D, showing Maaeve's earnings per weekend.

A linear inequality is a first-order term inequality that compares two values by the inequality symbols such as, '<', '>', '≤', '≠' or '≥'

In a linear inequality, m is the slope and b is the y-intercept with the x-intercept.

The amount Maeve currently has = $130

The number of weekends for the summer = 8

The least amount she wants to earn ≥ $1,250

130 + 8x ≥ 1,250

8x ≥ 1,250 130

8x ≥ 1,120

x ≥ 140

The length of DC is 26.1 cm.

The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Given:

BDC is a triangle and angles in a triangle sum up to 180° .

180 - 102° + 52°  = ∠BDC

180 - 154 = 26°

∠BDC = 26°

and, <ABD can be found same way since sum of interior angles in a triangle is 180°.

∠ABD  = 180 - 90 - 35

∠ABD = 55°

Using Trigonometry

sin 35° = opposite/hypotenuse

sin 35° = 12/BD

BD sin 35° = 12

BD = 12/sin 35°

BD = 12/0.57357643635

BD = 20.9213615475

BD ≈ 21 cm

Using sine formula

21/sin 52° = DC/sin 102°

DC sin 52° = 21 sin 102°

DC = 21 sin 102°/sin 52°

DC = 0.97814760073  × 21/0.7880107536

DC = 20.5410996154 /0.7880107536

DC = 26.0670295696

DC ≈ 26.1 cm(3 significant figures)

f(x)=-5/3x-14/3 is the formula for the function.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The function has a maximum point at (-4,2) and a minimum point at (-1,-3)

We have to find the formula for f(x).

Let the slope m=-3-2/-1+4

m=-5/3

Now let us find the y intercept

2=-5/3(-4)+b

2=20/3+b

2-20/3=b

Answer: 3.42x10^11

Step-by-step explanation:

The number 0.0000000000342 is equivalent to 3.42 × 10^-11. Hence, option B is the correct answer.

This type of conversion is called scientific notation.

Firstly we have to place a decimal between the two non-zero numbers which is 3.42.

And then, count the number of decimals that were moved. That is 11.

And then, determine whether the decimal point is to be moved to the left or right to return to the original number. If the decimal is moved right then the exponent is negative. If the decimal is moved left then the exponent is positive.

Here, the exponent is moved right and the decimal will be negative.

In this case, it is written as 3.42 × 10^-11.

Answer:

Either [tex]c = 12[/tex] or [tex]c = (-12)[/tex].

Step-by-step explanation:

Find the [tex]x[/tex]-coordinate of the intersection of the two curves by equating their [tex]y[/tex]-values and solving for [tex]x[/tex]:

[tex]x^{2} - c^{2} = c^{2} - x^{2}[/tex].

[tex]x^{2} = c^{2}[/tex].

[tex]x = c[/tex] or [tex]x = (-c)[/tex].

In other words, the two curves intersect both when [tex]x = c[/tex] and when [tex]x = (-c)[/tex].

Assume that [tex]c \ge 0[/tex]. The area enclosed would be over the range [tex](-c) < x < c[/tex]. Note that over this range, [tex]x^{2} \le c^{2}[/tex], so [tex]x^{2} - c^{2} \le 0 \le c^{2} - x^{2}[/tex]. The curve [tex]y = c^{2} - x^{2}[/tex] would be above [tex]y = x^{2} - c^{2}[/tex].

Integrate the upper curve minus the lower curve [tex](c^{2} - x^{2}) - (x^{2} - c^{2})[/tex] over this interval to find the area enclosed:

[tex]\begin{aligned}& \int\limits_{-c}^{c} \left((c^{2} - x^{2}) - (x^{2} - c^{2})\right)\, dx \\ =\; & \int\limits_{-c}^{c} \left(2\, c^{2} - 2\, x^{2}\right)\, dx \\ =\; & {\left[2\, c^{2}\, x - \frac{2}{3}\, x^{3}\right]}_{-c}^{c} && (\text{power rule}) \\ =\; & \left(2\, c^{2}\, c -\frac{2}{3}\, c^{3}\right) - \left(2\, c^{2}\, (-c) - \frac{2}{3}\, (-c)^{3}\right) \\ =\; & \frac{8}{3}\, c^{3} \end{aligned}[/tex].

In other words, assuming that [tex]c \ge 0[/tex], area enclosed between these two curves would be [tex](8/3)\, c^{3}[/tex]. Since this area is given, the value of [tex]c[/tex] can be found as:

[tex]\begin{aligned}c &= \sqrt[3]{\frac{3}{8}\, (\text{Area})} = 12\end{aligned}[/tex].

However, note that if [tex]c < 0[/tex], the order of limits of the integral would need to be reversed:

[tex]\begin{aligned}& \int\limits_{c}^{-c} \left((c^{2} - x^{2}) - (x^{2} - c^{2})\right)\, dx \\ =\; & \cdots \\ =\; & {\left[2\, c^{2}\, x - \frac{2}{3}\, x^{3}\right]}_{c}^{-c} \\ =\; & \left(2\, c^{2}\, (-c) - \frac{2}{3}\, (-c)^{3}\right) - \left(2\, c^{2}\, c -\frac{2}{3}\, c^{3}\right) \\ =\; & \left(-\frac{8}{3}\, c^{3}\right) \end{aligned}[/tex].

Hence, [tex]c = (-12)[/tex] would also be a solution to this question.

The theoretical probability of the spinner not landing on blue is 5/8

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

The probability of an event A is defined as the number of favorable outcomes divided by the number of total outcomes.

Since sections 1 and 8 are purple. Probability of purple = 2/8 = 1/4

Sections 2 and 3 are yellow. Probability of yellow = 2/8 = 1/4

Sections 4, 5, and 6 are blue. Probability of blue = 3/8

Section 7 is red. Probability of red = 1/8

The theoretical probability of the spinner not landing on blue can be determined by subtracting the probability of the spinner landing on blue from 1. That is:

P(not blue) = 1 - 3/8 = 5/8

The Stafford loan will have a higher balance of $114.84 at the time of repayment.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

The formula for compound interest compounded monthly is

A = P(1 + (r/12)/100)¹²ⁿ.

So, For Unsubsidized Stafford Loan,

A = 4980(1 + (6.25)/12/100)¹⁸.     (12 times 1.5 years two semesters and 6

In which the parameters of the equation are explained as follows:

The interest accrued is given as follows:

I(t) = Prt.

An amount of x was invested at 3% during one year with a return of R, hence:

R = 0.03x.

An amount of 4000 - x was invested at 4% during one year with a return of 155 - R, hence:

155 - R = 0.04x.

From the first equation, we have that:

x = R/0.03.

x = 33.3R.

Replacing into the second equation, the value of R is obtained as follows:

155 - R = 0.04(33.3R)

1.332R = 155

R = 155/1.332

R = $116.37.

Answer:An equilateral triangle with sides of length 48 inches can be divided into two right triangles by drawing a line from one vertex to the midpoint of the opposite side. The height of the equilateral triangle, or the length of the line segment from the vertex to the midpoint of the opposite side, is equal to the height of each of these right triangles.

Using the Pythagorean theorem, the length of the altitude of each right triangle can be found:

sqrt(48^2 - 24^2) = sqrt(2304) = 48 inches.

The area of each right triangle is 1/2 base * height, or 1/2 * 24 * 48 = 576 square inches.

Since the equilateral triangle is made up of two of these right triangles, the total area of the equilateral triangle is 2 * 576 = 1152 square inches.
