Sophie has 5 pieces of string that are 4 yards each. She uses 3 pieces that are each 3 feet long. How much string does Sophie ha

stich3 [128]

Alright, lets get started.

Sophie has 5 pieces of string that are 4 yards each.

1 yards = 3 feet,

So, 4 yards = $4 * 3 =12$ feet

Total number of string she has = 5 piece

So, total length she has = $5*12 = 60$ feet

It means she had 60 feet string in starting.

Now, She uses 3 pieces that are each 3 feet long, means

She uses = $3*3 = 9$ feet

So, remaining string length will be = $60 - 9 = 51$ feet

Means 51 feet string does Sophie have. : Answer

Hope it will help :)

The graph of f(x) = 2x + 4 shifts five units to the right when it is replaced with the graph of f(x) = 2x - k. What is the value

DIA [1.3K]

<h2>Answer</h2>

C.) 1

<h2>Explanation </h2>

Remember the rules for shifting functions:

$f(x)+b$ shifts the function b units upward

$f(x)-b$ shifts the function b units downward

$f(x+b)$ shifts the function b units to the left

$f(x-b)$ shifts the function b units to the right

Since we want tho shift $f(x)=2^{x+4}$ 5 units to the right, we are using the rule: $f(x-b)$ shifts the function b units to the right; in other words, we need to subtract 5 units to the input of the function:

$f(x)=2^{x+4-5}$

$f(x)=2^{x-1}$

But notice that there is already a negative sign in $f(x)=2^{x-k}$ , so to get $f(x)=2^{x-1}$ , k must be equal to positive 1.

<h2>○=> <u>Correct options</u> :</h2><h2>□ $\color{plum}\tt\bold{(C) \: SR = 27}$ </h2><h2>□ $\color{plum}\tt\bold{(D) \: QR = 54 }$ </h2><h3><u>Steps to derive the correct options</u> :</h3>

Since two sides and one included angle is equal in △PQS and △PRS, we can conclude that they are congruent under the SAS congruence criterion.

Which means :

▪︎Angle S = Angle S

▪︎PS = PS

▪︎QS = RS

Given :

Measure of segment QS = 6n+3

Measure of segment RS = 4n+11

Thus :

$= \tt6n + 3 = 4n + 11$
