The answer is 28.1 because since 9 is above 5 you would bump it up to the next number which is putting a one in the tenths place

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situa

Lina20 [59]

Answer:

$Expression = x + 150 +(- 26)$

$124 higher

Step-by-step explanation:

Given

$Deposit = \$150$

$Withdrawal = \$26$

Required

Represent the situation

Determine how much higher or lower is the remaining amount

Let the initial amount in his account be represented with x

When he deposited, the balance becomes

$Balance = x + 150$

When he withdrew, the balance becomes

$Balance = x + 150 + (-26)$

Hence, the algebraic expression is

$Expression = x + 150 +(- 26)$

Calculating how much higher or lower

$Balance = x + 150 + (-26)$

Open bracket

$Balance = x + 150 -26$

$Balance = x + 124$

Recall that the initial amount in the account is x

The difference between the balance and the x is as follows

$Difference = x + 124 - x$

$Difference = \$124$

Hence, the account has a higher of $124 after both transactions

I need help with this practice problem solving This is trigonometry from my ACT prep guide

Novay_Z [31]

Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

$f(x)=A\cos (\frac{2\pi}{T}x)+b$

In the given case, you have:

A = 4

T = 3π/4

b = -3

By replacing you obtain:

$\begin{gathered} f(x)=4\cos (\frac{2\pi}{\frac{3\pi}{4}}x)-3 \\ f(x)=4\cos (\frac{8}{3}x)-3 \end{gathered}$

Hence, the answer is:

f(x) = 4cos(8/3 x) - 3

What is the perimeter of ΔABC?

Serggg [28]

Answer:

Choice D: Perimeter = 5 + $\sqrt{65}$ + $\sqrt{34}$ units

Step-by-step explanation:

point B(9, 2) , point C(4, 5), point A (1,1)

Perimeter = D( A, C) + D (A, B) + D (B, C)

where D (A, C) = distance between A and C

so...

D(A, C) = root ( (4 - 1)^2 + (5 - 1)^2) = 5 from a 3-4-5 right triangle.

D(A, B) = root( (9- 1)^2 + (2 -1)^2) = root( 64 + 1) = root(65)

D(B, C) = root( (9 -4)^2 + (2 -5)^2) = root (25 + 9) = root(34)

Perimeter = 5 + root(65) + root(34)

Perimeter = 5 + $\sqrt{65}$ + $\sqrt{34}$ units
