Answer:

around 84.4

Step-by-step explanation:

you add the original price then the store price since that's how much they marked it up and the total would be 422 then you would find 20 percent of 422.

Answer:

The estimated answer is 400.

Step-by-step explanation:

Sticker price is $230

Store is having a sale, 20% off sticker price.

So first you have to do, $230 x 20% to get the price of 20%. Which is 46. Since it says off, you have to subtract. We just found out that $46 is 20%, we have to now take $46 away from the original sticker price, $230, So do

230 - 46, and you get 184. Therefore, $184 is the sticker price after the 20% sale. Now you add $184 to the price of the TV, $192. So do 192 + 184, which is 376. If you want to estimate it, it would be $400.

Answer:

Step-by-step explanation:

B, because -9.2 = -4.5, which is less than -4.12. Also, 17/4 = 4.25 is less than sqrt(20), which is 4.4721

What’s the answer to the top question and steps how to solve?

Leviafan [203]

Answer:

-3.69

Step-by-step explanation:

Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:

$Ln(a^b)=bLn(a)$

Now lets work out this problem:

$16^{2x+3}=13^{x-1}\\Ln(16^{2x+3})=Ln(13^{x-1})\\(2x+3)Ln(16)=(x-1)Ln(13)$

Using calculator, we take the values of Ln 16 and Ln 13 as:

Ln 16 = 2.7726

Ln 13 = 2.5649

Now, we can solve for x:

$(2x+3)Ln(16)=(x-1)Ln(13)\\(2x+3)2.7726=(x-1)2.5649\\5.5452x+8.3178=2.5649x-2.5649\\2.9803x=-10.8827\\x=-3.69$

x is -3.69 (rounded to 2 decimal places)

NEED THE ANSWER ASAP, PLEASE HELP!! What are the coordinates of the focus of the parabola?

Answer:

Vertex is (-8, 4) not one of the answers offered!

Step-by-step explanation:

Factor -1/8 out of the first two terms. Leave a space inside parentheses in which to add a number.

$y=-\frac{1}{8}(x^2 + 16x + \text{-----})-4$

Complete the square by squaring half the coefficient of x and adding it in the space.

$(\frac{16}{2})^2=64$

Add 64 in the space you made, then compensate for that at the end of the expression by subtracting $-\frac{1}{8}(64)=-8$

$y=-\frac{1}{8}(x^2+16x+64)-4+8\\y=-\frac{1}{8}(x+8)^2+4$

The x-coordinate of the vertex is the opposite of +8, the number inside the parentheses. The y-coordinate of the vertex is the number at the end of the expression.

V(-8, 4)
