A parabola and a circle are graphed into the standard (x,y) coordinate plane. The circle has a radius of 4 and is centered at (1

Gala2k [10]

Answer:

Correct answer: Two point of intersection and one touch point.

Step-by-step explanation:

Cartesian form of parabola is: y= a(x-1)² + 5 and point named A(2,4)

when we replace the coordinates of the point A in the formula we get

a = - 1 and parabola is y= - (x-1)² + 5 which means that it faces the opening downwards. The parabola touches the circle in vertex.

Justin deposited $2,000 into an account 5 years ago. Simple interest was paid on the account. He has just withdrawn $2,876. What

RSB [31]

Answer: 8.76%

Step-by-step explanation:

The formula to find the simple interest is given by :-

$I=Prt$ , where P is the principal amount, r is rate of interest () in decimal and t is the time ( in years). (1)

Given : Justin deposited $2,000 into an account 5 years ago.

i.e. P = $2,000 , t= 5 years

He has just withdrawn $2,876. i.e. Future value = $2,876

Interest (I)=$2,876-$2,000=$876 [Subtract Principal value from Future value]

Substitute all the above values of P , t , and I in the formula (1) , we get

$876 =(2000)r(5)\\\\\Rightarrow\ r=\dfrac{876 }{2000\times5}\\\\\Rightarrow r=\dfrac{876}{10000}=0.0876$

In percent , $r=0.0876\times100=8.76\%$

Hence, the rate of interest = 8.76%

mr. walker works as a salesperson at an electronics store. her earns $600 a week, plus $50 for a every computer he sells. write

harkovskaia [24]

Answer:

The number of computer must Mr. walker sale that week to earn at least $ 1250 is 13 .

Step-by-step explanation:

Given as :

The earning of Mr . walker = $ 600 per week + $ 50 for every computer he sell

Let The number of computer does he must sell to earn $ 1250 for the week = n computers

Now, According to question

$ 600 per week + $ 50 × number of computer he sale = total earning that week

Or, $ 600 per week + $ 50 × number of computer he sale = $ 1250

Or, $ 600 per week + $ 50 × n = $ 1250

or, $ 50 × n = $ 1250 - $ 600

Or, $ 50 × n = $ 650

∴ n = $\frac{650}{50}$

I.e n = 13

So, number of computer must he sale to earn $ 1250 = n = 13

Hence The number of computer must Mr. walker sale that week to earn at least $ 1250 is 13 . Answer
