When f(x)=0 x=-1, 0, 8

F(x) = 0 is the same as saying y = 0. When y = 0, the line will cross the x-axis. Look for where the line crosses the x-axis.

The line crosses the x-axis at x = -1, x = 0, and x = 8. At these x-points, y will equal 0.

The answer is 'When f(x) = 0, x = -1, 0, -8.'

A geographer found that the land area of Aruba is 75 square miles and the land area of Bermuda is 19 square miles. Based on thes

MakcuM [25]

The interpretation of<em> </em><em>x</em> in the equation 75•x + 19•y = T, used by the geographer, based on the land area of Aruba, 75 m², and Bermuda, 19 m², is the population in a square mile of Aruba

<h3>Which method can be used to find the interpretation of <em>x </em>in the equation?</h3>

The land area of Aruba = 75 m²

Land area of Bermuda = 19 m²

The total number of residents is given in the question by the equation;

75•x + 19•y = T

Therefore;

x = The number of people in a square mile in Aruba

y = The number of people in a square mile in Bermuda

Which gives;

The interpretation of the variable, <em>x </em>in the context is the population of Aruba per square mile.

Hey can you please help me posted picture of question

Debora [2.8K]

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

$x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}$

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15

Using the values, we get:
$x= \frac{11+- \sqrt{121-4(2)(15)} }{2(2)} \\ \\ 
x= \frac{11+-1}{4} \\ \\ 
x=3, x= 2.5$

So, the correct answer to this question are option B and D

A ball is thrown upward from the top of a 40 foot high building at a speed of 80 feet per second. The ball's height above

tekilochka [14]

it takes 5 seconds to reach a height of 40 ft. and It takes 2.5 seconds to reach maximum height.

Let h(t) represent the height of the ball at time t.

Given that the height is given by:

h(t) = -16t² + 80t + 40

1) For the ball to reach a height 0f 40 ft, h(t) = 40, hence:

40 = -16t² + 80t + 40

16t² - 80t = 0

t(t - 5) = 0

t = 0 or t = 5

Hence it takes 5 seconds to reach a height of 40 ft.

2) The maximum height is at h'(t) = 0,

h'(t) = -32t + 80

-32t + 80 = 0

32t = 80

t = 2.5

It takes 2.5 seconds to reach maximum height.

Alborosie

Answer:

Bolt A will fit Nut A and Nut B

Step-by-step explanation:

We have the following statements:

Nut C fits on Bolt C.

Nut B fits on Bolt B.

Nut A fits on Bolt A.

Bolt C is larger than Bolt B.

Bolt A and Bolt B are exactly the same.

Then we can say that Bolt A will fit Nut A and Nut B...
