1/7-11/2:(3×2+5)/4-(2-1×7)/7
= 1/7-11/2: 11/4 +5/7
= 1/7-11/2 ×4/11 +5/7
=1/7 -2 +5/7
=(1 -2×7 + 5)/7
=(1-14+5)/7
=-8/7➡ANS

❇NOTE:
↪Same rule is applied here like in the question before....
▶solve ( ) bracket first
▶ : means ratio sign and is same as / sign
▶DMAS rule is followed throughout the question

▶11/2: 11/4=11/2× 4/11 ...here ratio sign can be converted into Multiplication sign by reciprocating the term after : sign

A man traveled 24 miles in 20 minutes and 18 miles in 15 minutes. Assume that the distance varies linearly with time. How far wi

Norma-Jean [14]

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles

According to the Rational Root Theorem, the following are potential roots of f(x) = 60x2 – 57x – 18. Which is an actual root of

emmainna [20.7K]

Answer: The correct option is third, i.e., $-\frac{1}{4}$ .

Explanation:

The given function is,

$f(x)=60x^2-57x-18$

The Rational Root Theorem states that the rational roots are in the form of,

$r=\frac{\text{factors of constant term}}{\text{factor of leading coefficient}}$

These rational roots are possible rational roots not the actual roots of f(x).

For actual roots of f(x), the value of the function is 0.

Put each value of x from the option in the function, if we get the value of f(x) is 0, then that value is the actual root of f(x).

Put x=3.

$f(3)=60(3)^2-57(3)-18=351\neq 0$

Put x=6

$f(6)=60(6)^2-57(6)-18=1800\neq 0$

Put $x=-\frac{1}{4}$

$f(-\frac{1}{4})=60(-\frac{1}{4})^2-57(-\frac{1}{4})-18=0$

Put $x=-\frac{6}{5}$

$f(-\frac{6}{5})=60(-\frac{6}{5})^2-57(-\frac{6}{5})-18=136.8\neq 0$

Only for $x=-\frac{1}{4}$ the value of function is 0, therefore the correct option is third.

Scientists studied a deer population for 10 years. They generated the function f(x) = 248(1.15)x to approximate the number of de

tamaranim1 [39]

For this case we have an exponential function of the form:

$f (x) = A (b) ^ x$

Where,

A: the initial number of deer
b: rate of change
x: number of years

We then have the following function:

$f (x) = 248 (1.15) ^ x$

After three years we have:

$f (x) = 248 (1.15) ^ 3\\f (x) = 377$

Answer:

the population 3 years after beginning the study is 377.

Find the slope of the line (-4,4) (-3,-2)

AlexFokin [52]

Answer:

$-6$

Step-by-step explanation:

The formula for finding slope is

$\frac{y_{2} -y_{1}}{x_2-x_1}$

Inserting your numbers would make the equation look like this:

$\frac{-2-4}{-3+4}$

Simplify:

$\frac{-6}{1}$
