Answer:

I’m assuming you’re talking about what percentage was taken off, so in that case the answer would be approximately 20.6%

Step-by-step explanation:
67.5/85 X/100

cross multiply then divide by 100 to find for x and you get 79.4117

then, subtract this number from 100 and you will get 20.6%

Which graph shows data that would result in the most accurate prediction of the number of games a baseball team will win in a se

Lynna [10]

Any graph that can be used to accurately predict number of games a baseball team will win in a season based on the total number of home runs scored that season will be a graph that has home runs on the x-axis and wins on the y-axis.

<h2>Straight line graph</h2>

A straight line graph is a graph that obeys the equation; y = mx + c

m = slope
c = intercept

For there to be the possibility of prediction, the graph must increase or decrease linearly.

Therefore, any graph that can be used to accurately predict number of games a baseball team will win in a season based on the total number of home runs scored that season will be a graph that has home runs on the x-axis and wins on the y-axis. Points are grouped together in a line and increase.

a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. wri

Natasha2012 [34]

Answer: -6<x<5

Step-by-step explanation:

Given

Length is 3 m more than three times the width

Suppose width is x

So, the length is 3x+3

The area of a rectangle is $length\times width$

Area= $(3x+3)x$

$\Rightarrow 3x^2+3x-90$

F(x)=cos(x). Find the x-intercepts of f(x) on [0, 2).

balu736 [363]

The x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2

<h3>What is the x-intercept of the function?</h3>

The x-intercept of the function is the point or points where the graph of the function crosses the x-axis i.e. the point where the function equals 0

<h3>How to find the x-intercepts of the function?</h3>

The function is given as

f(x) = cos(x)

And the interval is given as

[0, 2)

The above means that we determine the value of x when the function f(x) equals 0

So, we have

cos(x) = 0

The above equation can be solved graphically

See attachment for the graph of the function f(x) = cos(x)

In the interval [0, 2), the graph crosses the x-axis at points x = π/2 and 3π/2

Hence, the x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2
