Answer:

  $3213

Step-by-step explanation:

You want to know the total spent on rent and food if rent is 7/20 of your budget and food is 1/2 of your budget of $3780 per month.

The amount spent on each item is the product of the fraction of the budget it is and the total amount being budgeted (your income).

  rent = 7/20 × 3780 = 1323

  food = 1/2 × 3780 = 1890

The total spent on these items is the sum of these amounts:

  rent + food = 1323 +1890 = 3213

A total of $3213 is budgeted for rent and food.

__

Additional comment

Your calculator can figure this handily.

You can factor out the income amount and add the fractions first:

  (7/20·3780) +(1/2·3780) = 3780(7/20 +1/2) = 3780(7/20 +10/20)

  = 3780(17/20) = 3213

The value of c according to the given equation as described is; -14.

The other root of the equation in discuss is; 7.

As evident in the task content; if -2 is the root of a quadratic equation x²-5x+c=0, then x = -2 holds true for the equation; therefore, we have;

a). (-2)² - 5 (-2) + c = 0

4 + 10 + c = 0

c = -14

Hence, the value of c is; -14.

b). By substituting into the equation; we have;

Answer:

  g(x) = e^(x+2) -3

Step-by-step explanation:

You want the transformed function g(x) of the parent function f(x) = e^x given that g(x) has a horizontal asymptote of -3 and goes through the point (-2, -2).

The parent function goes through the point (0, 1), which has apparently been translated to (-2, -2) by the transformation. That translation looks like ...

  g(x) = f(x -h) +k . . . . . . . . f(x) translated h units right and k units up

Our function has been translated from 0 to -2 in the horizontal direction, or left 2 units: h = -2.

It has been translated from 1 to -2 in the vertical direction, or down 3 units: k = -3.

Then the translated function is ...

  g(x) = f(x +2) -3

  g(x) = e^(x+2) -3

The probability that a randomly chosen appointment is with a patient under 18 years old or is for regular cleaning is 0.95.

The probability of a random appointment being with a patient under 18 or for regular cleaning is calculated as P(Under 18 or Regular Cleaning) = P(Under 18) + P(Regular Cleaning) - P(Under 18 and Regular Cleaning).

P(Under 18) = 0.9

P(Regular Cleaning) = 0.15

P(Under 18 and Regular Cleaning) = 0.14

So, P(Under 18 or Regular Cleaning):

= 0.9 + 0.15 - 0.14

The number that goes in the box is 4, since 4 + (-2) = 2, which is the coefficient of x^2 in the equation. The third step is to add the same number to both sides of the equation, so the box needs to contain 4.

To complete the third step in solving a quadratic equation using the completing the square method, the number that goes in the box is 4. This is because the goal is to make the coefficient of x^2 on the left side of the equation equal to the coefficient of x^2 on the right side. The equation is x^2 - 8x + 2 = 0, so the coefficient of x^2 on the left side is 1, and the coefficient of x^2 on the right side is 2. Therefore, the number that needs to be added to the left side is 1, and the number that needs to be added to the right side is also 1. This means that 4 needs to be added to both sides of the equation, so 4 is the number that goes in the box.

The area the polygon in the diagram with, a length from the center to the vertex 6√2 in is 144.0 in².

Any closed curve that consists entirely of connected line segments (sides) without any intersections is known as a polygon in geometry. The three simplest polygons are pentagons, triangles with three sides, and quadrilaterals with four sides (five sides). The two types are concave and convex polygons.

Convex polygons are those without any extended sides crossing over them. Equilateral refers to a polygon with equal sides. Interior angles of equiangular shapes are equal. Every equilateral and equiangular polygon is a regular polygon (e.g., an equilateral triangle or a square).

As all sides are equal, all diagonals are equal too, and the angle of adjacent diagonals are 90° with vertical opposite angle.

Therefore,

Each side = [tex]\sqrt{\text {diagonal}^2+ \text {diagonal}^2}[/tex]

Each side = [tex]\sqrt{(6\sqrt{2} )^2+(6\sqrt{2} )^2}[/tex]

Each side = [tex]\sqrt{(36\times 2+36\times 2}[/tex]

Each side = [tex]\sqrt{144}[/tex]

Each side = 12 inch

Area =  12 × 12

Step-by-step explanation:

We will denote the almirahs as A1 and A2 for ease of explanation. I am omitting currency until the final answer

For the following computations note that x% = x/100 in decimal so
15% = 15/100 = 0.15
13 1/3% = 13 1/3 ÷ 100 = 40/3 ÷ 100 = 40/300

Cost of A1 = 4800

A1 was sold for a loss of 15%

Loss = 15% of 3640 = 0.15 x 3640  = Rs 546

A2 bought at 4800 was sold at a gain of 13 1/3%

Gain from sale = 13 1/3% of 4800 = 40/300 x 4800 =Rs 640

We have to treat gain as positive and loss as negative to arrive at the answer

Net gain/loss = 640  - 546 = Rs. 94

The Riemann sum formula is ∫(1,5) 2x = 24

From the question, we have the following parameters that can be used in our computation:

f(x) = 2x over the interval [1, 5]

The Riemann sum for f(x) = 2x over the interval [1,5] using the right-hand endpoint for each subinterval is given by the formula:

(Δx/2) * (2c1 + 2c2 + ... + 2cn) where c1, c2, ..., cn are the right-hand endpoints of the subintervals and Δx = (b - a)/n.

As a general rule:

As n approaches infinity, the width of the subintervals approaches zero,

Also, we have the Riemann sum approaches the definite integral of f(x) = 2x over the interval [1,5], which is x² evaluated at the interval's endpoints.

So, the formula becomes

∫(1,5) 2x = x²

Substitute the intervals

∫(1,5) 2x = 5² - 1²

Evaluate

∫(1,5) 2x = 24

Hence, the formula is ∫(1,5) 2x = 24
