Which rule describes a translation that is 8 units to the right and 2 units up?

Fofino [41]

(x-8, y+2).

When translating figures, a translation to the right subtracts from the x-coordinate (sort of the opposite of how we think of graphs that go to the right). Translations up would be adding to the y-coordinate.

Two chords in a circle intersect. One chord is made of 6 and 5, and the other is made of x +1 and x. What is x?

Zolol [24]

Answer:

x = 5 and -6

Step-by-step explanation:

Using the intersecting chord theorem which states that the products of the lengths of the line segments on each chord are equal.

Hence:

let

a = 6, b = 5, c = x+1 and d = x

Therefore, ab = cd

6*5 = x(x+1)

30 = x²+x

x²+x - 30 = 0

x²+ 6x - 5x - 30 = 0

x(x+6) - 5(x+6) =0

(x-5)(x+6) = 0

x-5 =0 and x+6 = 0

x = 5 and -6

Which is the graph of y= cos(x-pi)

marshall27 [118]

Answer:

graph attached

Step-by-step explanation:

A graph is a pictorial representation that represent the relationship between two or more things.

Cosine function is periodic with period $2\pi$ . If the point $(x,y)$ lies on the graph, point $(x+2k\pi ,y)$ will also lie on the graph where k is any integer.

Here,

$cos(x-\pi )=cos[-(\pi -x)]=cos(\pi -x)=-cos x$

Bart budgeted $285.75 each month for utilities. His utility bills this month were $130.50 for electric, and $240 for gas. How mu

iren2701 [21]

Answer:

$84.75 over budget

Step-by-step explanation:

Barts' budget is 285.75

Bills: 240 + 130.50 = $370.50

(subract by his budget)

370.5 - 285.75 = $84.74

In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment t

GaryK [48]

Using an exponential function, it is found that the mass of the radioactive sample at the beginning of the 13th day of the experiment was of 169.1 mg.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

At the beginning of the first day of the experiment the mass of the substance was 500 grams and mass was decreasing by 8% per day, hence A(0) = 500, r = 0.08, and the equation is given by:

$A(t) = A(0)(1 - r)^t$

$A(t) = 500(1 - 0.08)^t$

$A(t) = 500(0.92)^t$

At the 13th day, the mass is given by:

$A(13) = 500(0.92)^{13} = 169.1$
