Answer:

$48.98

Step-by-step explanation:

first move the decimal of your percent 2 places

8.6% = .086

then multiply by 53.58

.086 × 53 58= 4.60

subtract 4.60 from 53.58

53.58 - 4.60= 48.98

The formula for calculating the area of a circle is A = π​r​2 where pi (π) equals 3.14 and the radius (​r​) is half the diameter.

You must times 5 by 5 because of exponents and then times it by pie

5 times 5 = 25

25 times pie is 78.5

The circumference of the circle with a diameter of 6 cm will be 18.84 cm.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let d be the diameter of the circle. The circumference of the circle will be given as,

C = πd units

The diameter of the circle is 6 cm. Then the circumference is given as,

C = π x 6

C = 3.14 x 6

C = 18.84 cm

The circumference of the circle with a diameter of 6 cm will be 18.84 cm.

Answer:

[tex]-\frac{5}{4}[/tex]

Step-by-step explanation:

We are given two fractions and are asked to simplify it.

So

[tex](-\frac{4}{5} )^9 / (-\frac{4}{5} )^{10}[/tex]

We can follow the exponent rule of subtracting them since both fractions are the same value.

[tex](-\frac{4}{5} )^{9-10}[/tex]

[tex](-\frac{4}{5} )^{-1}[/tex]

Now do the negative exponent rule :

[tex]\frac{1}{-\frac{4}{5} }[/tex]

Move the negative in between the fraction :

[tex]-\frac{1}{\frac{4}{5} }[/tex]

And apply the fraction switcharoo :

[tex]\frac{5}{4}[/tex]

Answer:

[tex]x = \frac{y}{3} - \frac{5}{3}[/tex]

Step-by-step explanation:

Given

[tex]y = 5 + 3x[/tex]

Required

Solve for x

Subtract 5 from both sides

[tex]y-5 = 5 -5+ 3x[/tex]

[tex]y-5 = 3x[/tex]

Divide through by 3

[tex]\frac{y}{3} - \frac{5}{3} = x[/tex]

[tex]x = \frac{y}{3} - \frac{5}{3}[/tex]

Answer:

Step-by-step explanation:

...

Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value.

A two-dimensional coordinate plane called the cartesian plane is what is created when the x- and y-axes cross. The origin is the place where the x-axis and y-axis meet perpendicularly.

A pair of perpendicular lines connect to create the cartesian plane, a two-dimensional coordinate plane. The term "Y-axis" refers to the vertical line, whereas "X-axis" refers to the horizontal line. The Cartesian coordinate point (x, y) indicates that the point's horizontal and vertical distances from the origin, respectively, are x and y, respectively. If x has a positive sign, the point will be to the right of the origin.

Given, Arionna needed to graph triangle PQR reflected across the y-axis.

Arionna’s Work:

Blue right-arrow red. P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8).

Reflection across y axis

(x , y) becomes ( - x , y)

P ( 3 , 7)    P ' (  3 , -7)   The correct solution should have been ( -3 , 7),

Q ( 0 , 4)   Q'  ( 0 , 4)   This is correct,

R  (5 , 8)    R' (-5 , 8)   This is correct,

Arionna was unable to determine P's proper point. Not the y-value, but the x-value should have been negated instead.

The graph of Arionna

The points of a red triangle on a coordinate plane are (-7, 3), (-5, 8), and (0, 4).

When graphing P"s coordinates (3, -7), Arionna reversed their order.

A blue triangle has points (0, 4), (3, 7), (5, 8).

Hence Arionna Graph is attested in image.

Answer:

it's the fourth answer

Step-by-step explanation:

(X-4) (X-4)

[tex]x^{2}[/tex]-4x-4x+16

[tex]x^{2}[/tex]-8x+16

The expression is x² + 8x + 16. The correct answer is a) x² + 8x + 16.

To multiply (x - 4)², we can use the concept of expanding a binomial squared. The formula for expanding a binomial squared is:

(a - b)² = a² - 2ab + b²

In this case, a = x and b = 4. Substituting these values into the formula, we have:

(x - 4)² = x² - 2(x)(4) + 4²

= x² - 8x + 16

Therefore, the correct option is a) x² + 8x + 16.

Answer:

[tex]b=8[/tex]

Answer:

See Explanation

Step-by-step explanation:

To do this, we will make use of the following rules:

Direct Variation: [tex]a\ \alpha\ b[/tex] => [tex]a = kb[/tex]

Inverse Variation: [tex]a\ \alpha\ \frac{1}{b}[/tex] ==> [tex]a = k/b[/tex]

Joint Variation: [tex]a\ \alpha\ bc[/tex] ==> [tex]a= kbc[/tex]

Direct, then inverse variation: [tex]a\ \alpha\ b\ \alpha\ \frac{1}{c}[/tex] ==> [tex]a= kb/c[/tex]

Having highlighted the rules, the solution is as follows:

1. m varies directly to a

[tex]m\ \alpha\ a[/tex]

[tex]m =ka[/tex]

2. p varies inversely as q.

[tex]p\ \alpha\ \frac{1}{q}[/tex]

[tex]p\ = k\frac{1}{q}[/tex]

3. [tex]r\ varies[/tex] directly as s and inversely as t.

[tex]r\ \alpha\ s\ \alpha\ \frac{1}{t}[/tex]

[tex]r = k\frac{s}{t}[/tex]

4. z varies jointly as [tex]e\ and\ f.[/tex]

[tex]z\ \alpha \ ef[/tex]

[tex]z = kef[/tex]

5. F varies directly as the [tex]square\ of\ t.[/tex]

[tex]F\ \alpha\ t^2[/tex]

[tex]F = kt^2[/tex]

6. d varies jointly r and t

[tex]d\ \alpha\ rt[/tex]

[tex]d = krt[/tex]

7. P is inversely proportional to h.

[tex]P\ \alpha\ \frac{1}{h}[/tex]

[tex]P= \frac{k}{h}[/tex]

8. P varies directly as V

[tex]P\ \alpha\ V[/tex]

[tex]P=kV[/tex]

9. d varies directly as the square of  t

[tex]d\ \alpha\ t^2[/tex]

[tex]d = kt^2[/tex]

10. s varies jointly as  b and d and inversely as the  square L

[tex]s\ \alpha\ bd\ \alpha\ \frac{1}{L^2}[/tex]

[tex]s = k\frac{bd}{L^2}[/tex]

The translation of each statement to an equation using k as the constant of variation is

1. m varies directly to a.

m = k × a

m = ka

2. p varies inversely as q

p = k / q

3. r varies directly as s and inversely as t

r = (k × s) / t

r = ks / t

4. z varies jointly as e and f.

z = k × e × f

z = kef

5. F varies directly as the square of t.

F = k × t²

F = kt²

6. The distance (d) traveled by a car varies jointly as the rate (r) and the time (t) of travel.

d = k × r × t

d = krt

7. The air pressure (P) in inversely proportional to the altitude (h).

P = k / h

8. The amount of water pressure (P) in a closed container varies directly as the volume (V) of the

water.

P = k × V

P = kV

9. The distance (d) of a falling body varies directly as the square of the time (t) traveled.

d = k × t²

d = kt²

10. The stiffness (s) of a beam varies jointly as its breadth (b) and depth (d) and inversely as the

square of its length (L).

s = (k × b × d) / L²

s = kbd / L²
