PLEASE HELP, I'LL GIVE 90 POINTS, I JUST RLLY NEED SOMEONES HELP RN

Step-by-step explanation:

Rounding to the nearest hundredth means the rounding of any decimal number to its nearest hundredth value. In decimal, hundredth means 1/100 or 0.01. For example, the rounding of 2.167 to its nearest hundredth is 2.17.

You didn't show her answer so I don't know her mistake, but you round to the nearest hundredth by looking at the ten's value, if it's a 5 or greater, add one to the hundredths digit. If its lesser than five, leave the hundredth place.

Ex. Rounding 1,567. Because the tens digit is a 6, you round the 5 up to a 6 and get rid of the tens and one digit. 1,567 rounds to 1,600

Ex. Rounding 1,445. Because the tens digit is a 4, you leave the hundredths digit and get rid of the rest. 1,445 rounds to 1,400.

Hope this helps!

Step-by-step explanation:

Using angle sum property for angles For, the given triangle, the value of x = 23°

The angle sum feature is a characteristic shared by all varieties of triangles. Triangles have an angle sum property of 180 degrees. This indicates that a triangle's internal angles add up to 180 degrees.

The angle 135 ,makes a linear pair with the line

So, the angle will be -

180 - 135

= 45°

Using angle - sum property,

x + 45 + 112 = 180

x + 157 = 180

x = 180 - 157

x = 23

The values of a and b are 8 and 54 respectively

The given parameters are:

WVY= 4a + 58

XVY = 2b - 18

From the question, we understand that WX is perpendicular to YZ

This means that

WVY= 90

XVY = 90

So, we have

4a + 58 = 90

2b - 18 = 90

Solve for a in 4a + 58 = 90

4a = 90 - 58

Evaluate

4a = 32

Divide by 4

a = 8

Solve for b in 2b - 18 = 90

2b = 90 + 18

Evaluate

2b = 108

Divide by 2

b = 54

Hence, the values of a and b are 8 and 54 respectively

Answer:

L = 32

W = 8

Step-by-step explanation:

Set it up algebraically:

A = L x W

A = 40 m^2

L = 4w

40 = 4w x w

40 = 5w

40/5 = 5w/5

W = 8

L = 4(8)

L = 32

Answer:

x = 1, x = 3

Step-by-step explanation:

Given function:

[tex]f(x)=\left(\log(3x)-2 \log(3)\right) \cdot \left(x^2-1\right)[/tex]

The roots of the function are when f(x) = 0:

[tex]\begin{aligned}f(x) & = 0\\ \implies \left(\log(3x)-2 \log(3)\right) \cdot \left(x^2-1\right) & = 0\\\\ \textsf{Therefore,} \:\:\:\log(3x)-2 \log(3) & = 0\\ \textsf{and }\:\:\:x^2-1 & = 0 \end{aligned}[/tex]

Case 1

[tex]\begin{aligned}\left(\log(3x)-2 \log(3)\right) & = 0\\\log(3x) & = 2 \log(3)\\ \log(3x) & = \log (3)^2\\ \log(3x) & = \log (9)\\ 3x & = 9\\ x & = 3\end{aligned}[/tex]

Case 2

[tex]\begin{aligned}\left x^2-1\right & = 0\\x^2 & = 1\\ x & = \pm 1\end{aligned}[/tex]

As logs of negative numbers cannot be taken, x = 1 only.

Therefore, the roots of the given function are: x = 1, x = 3

Answer:

7/4≤x ≤-1

Step-by-step explanation:

Given the set of inequalities

−5x−3≥2 and 4x−2≥5

We are to write the solution in interval notation. We need to solve them individually first as shown;

For −5x−3≥2

add 3 to both sides

−5x−3+3≥2+3

-5x ≥5

divide both sides by -5 (note that dividing by a negative value will change the sense of the inequality sign)

-5x/-5 ≤5/-5

x ≤ -1

For the inequality 4x−2≥5;

add 2 to both sides

4x−2+2≥5+2

4x≥7

divide both sides by 4;

4x/4 ≥ 7/4

x≥7/4 or 7/4≤x

Combining 7/4≤x and x ≤ -1, the solution in interval notation is expressed as 7/4≤x ≤-1

Correct answer is D. The statement that shows Sam's purpose for making the investment,  is; Sam wants an investment that offers a higher return than stocks.

Sam desires an investment that delivers a larger return than stocks, which is the phrase that best demonstrates his motivation for making the investment.

Bonds are a sort of investment that may be held for a time in the hopes of earning returns, as is common knowledge. The two most popular forms of investments traded on the stock market are bonds and stocks. Buyers just hold them in the belief that they will generate returns.

Bonds, however, are often safer investments than stocks. In actuality, stocks are a type of investment that is excessively volatile.

Answer:

b) -8

c) 11

d) {x is a member of all real numbers | except for 2}

Answer:

(a) Choice C is correct

(b) f(x) = -8  Point is (1, -8)

(c) x =11  Point is at (11,2)

(d) Domain of f is x is [tex]\:x < 2\quad \mathrm{or}\quad \:x > 2\:[/tex]  
    In interval notation [tex]\:\left(-\infty \:,\:2\right)\cup \left(2,\:\infty \:\right)[/tex]

(e)  x intercept is at x = -7

(f) y-intercept is at [tex]-\frac{7}{2} = -3.5[/tex]

Step-by-step explanation:

(b) Plug in x = 1 into the equation [tex]\:\:\frac{x+7}{x-2} = \frac{1+7}{1-2} = \frac{8}{-1} = -8[/tex]

(c) If f(x) = 2 then we get [tex]2 = \:\:\frac{x+7}{x-2}[/tex]  

==> 2(x-2) = x + 7

==>   2x - 4 = x + 7

==> 2x - x = 7 +4 =11

==>  x = 11

(d) Domain of f is all values of x -∞ < x < ∞ except at x = 2 since at x = 2 the denominator is 0 and division by zero is undefined; So we can say the domain is x < 2 or x  >2

(e) To get the x-intercept set y = 0 and solve for x
We get (x+7)/(x-2) = 0

x+7 = (x-2)(0) = 0

x = -7 and the x intercept is at point (-7, 0)

(f) [tex]y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0[/tex]

Substitute for x = 0 to get y = (0+7)/(0-2) = -7/2

The Algebra of Functions

Like terms, functions may be combined by addition, subtraction, multiplication or division.

Example 1. Given f ( x ) = 2x + 1 and g ( x ) = x2

+ 2x – 1 find ( f + g ) ( x ) and

( f + g ) ( 2 )

Solution

Step 1. Find ( f + g ) ( x )

Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;

( f + g ) ( x ) = ( 2x + 1 ) + (x2

+ 2x – 1 )

= 2x + 1 + x2

+ 2x – 1

= x

2

+ 4x

Step 2. Find ( f + g ) ( 2 )

To find the solution for ( f + g ) ( 2 ), evaluate the solution above for 2.

Since ( f + g ) ( x ) = x2

+ 4x then;

( f + g ) ( 2 ) = 22

+ 4(2)

= 4 + 8

= 12

Example 2. Given f ( x ) = 2x – 5 and g ( x ) = 1 – x find ( f – g ) ( x ) and ( f – g ) ( 2 ).

Solution

Step 1. Find ( f – g ) ( x ).

( f – g ) ( x ) = f ( x ) – g ( x )

= ( 2x – 5 ) – ( 1 – x )

= 2x – 5 – 1 + x

= 3x – 6

Step 2. Find ( f – g ) ( 2 ).

( f – g ) ( x ) = 3x – 6

( f – g ) ( 2 ) = 3 (2) – 6

= 6 – 6

= 0

Answer: 15-2x

The solution of the geometric system is (x, AB, BC, AC) = (10, 14, 19, 33).

In accordance with geometry, three points are collinear if and only if these points lie on the same line. Then, the geometric system is represented by the following model:

AC = AB + BC

If we know that AB = x + 4, BC = 2 · x - 1 and AC = 4 · x - 7, then the value of x and the lengths of the line segments are, respectively:

4 · x - 7 = (x + 4) + (2 · x - 1)

4 · x - 7 = 3 · x + 3

x = 10

AB = 10 + 4

AB = 14

BC = 2 · 10 - 1

BC = 20 - 1

BC = 19

AC = 4 · 10 - 7

AC = 40 - 7

AC = 33
