The sum of 7 to the 9th power and y is expressed as 7⁹ + y

This statement will result in an exponential equation since we will have a base and an exponent

7 raise to the 9th power is expressed as 7⁹

Taking the sum of the result and y;

The final expression will be 7⁹ + y

Hence the sum of 7 to the 9th power and y is expressed as 7⁹ + y

The graph of the function f(x) = (x + 6)(x + 2) is shown. Which statements describe the graph? Check all that apply.

dedylja [7]

Answer: The correct statements are ,

The domain is all real numbers.

The function is negative over (–6, –2).

The axis of symmetry is x = –4. .

Given that,

Function f(x) = (x + 6)(x + 2) .

We have to find,

The vertex, axis of symmetry, domain for the given function f(x).

The vertex represents the lowest point on the graph or the minimum value of the quadratic function.

Which is x = -6 for the function f(x).

So, The vertex is the minimum value x = -6.

The axis of symmetry is the vertical line that goes through the vertex of a parabola so the left and right sides of the parabola are symmetric.

Axis of symmetry =

So, f(x) = (x + 6)(x + 2) =

Then, Axis of symmetry = = -4.

The domain of a quadratic function f(x) is the set of x -values for which the function is defined.

The domain for f(x) = (x + 6)(x + 2) is -6 and -2 which are all real number.

A function is called monotonically increasing (also increasing or non-decreasing).

The function is increasing over (–∞, –6) for function f(x) = (x + 6)(x + 2) .

The y-value decreases as the x-value increases: For a function y = f(x): when < then, The function is negative over (–6, –2).

The sum of two numbers is 18, 5 times the number subtracted from 4 over 7 of the second number is 14 find the number

AURORKA [14]

Answer:

First number x = -0.6

Second number y = 18.66

Step-by-step explanation:

Let the first number = x

and Second number = y

Sum of two numbers is 18. We can write it in mathematical expression as:

$x+y=18$

5 times the number subtracted from 4 over 7 of the second number is 14. We can write it in mathematical expression as:

$\frac{4}{7}y-5x=14$

So, solving the equations simultaneously we can find value of x and y

Let:

$x+y=18--eq(1)\\\frac{4}{7}y-5x=14--eq(2)$

Finding value of x from equation 1 and put it in eq(2)

$x+y=18\\x=18-y$

Put in equation 2

$\frac{4}{7}y-5(18-y)=14\\\frac{4}{7}y-90+5y=14\\\frac{4y-90*7+5y*7}{7}=14\\ \frac{4y-90*7+5y*7}{7}=14\\ \frac{4y-630+35y}{7}=14\\ \frac{39y-630}{7}=14\\39y-630=14*7\\39y-630=98\\39y=98+630\\39y=728\\y=18.66$

So, Value of y= 18.66

Now finding value of x, By putting value of y in eq(1)

$x+y=18\\18.66+x=18\\x=18-18.66\\x=-0.6$

So, First number x = -0.6

Second number y = 18.66

A highway makes an angle of 6 degrees with the horizontal. This angle is maintained for a horizontal distance of 8 miles

lyudmila [28]

Complete Question

A highway makes an angle of 6 degrees with the horizontal. This angle is maintained for a horizontal distance of 8 miles

To the nearest hundredth of a mile, how high does the highway rise in this

*mile section?

Answer:

$h=0.84miles$

Step-by-step explanation:

From the question we are told that:

Angle $\theta = 6 \textdegree$

Horizontal distance traveled $d=8miles$

Generally the Trigonometric equation for Height is mathematically given by

$Tan \theta=\frac{h}{5}$

$h=8*tan(6)$

$h=0.84miles$
