what is 8 thousandths less than 4.989?

Answer:

see explanation

Step-by-step explanation:

(13)

v² - 11v + 18 = 0 ← in standard form

(v - 2)(v - 9) = 0 ← in factored form

Equate each factor to zero and solve for v

v - 2 = 0 ⇒ v = 2

v - 9 = 0 ⇒ v = 9

solutions are v = 2, v = 9

(14)

5x² - 12x + 7 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 7 = 35 and sum = - 12

The factors are - 5 and - 7

Use these factors to split the x- term

5x² - 5x - 7x + 7 = 0 ( factor the first/second and third/fourth terms )

5x(x - 1) - 7(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(5x - 7) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

5x - 7 = 0 ⇒ 5x = 7 ⇒ x = [tex]\frac{7}{5}[/tex]

solutions are x = 1, x = [tex]\frac{7}{5}[/tex]

Step-by-step explanation:

Answer:

1.

1) The area of the sector is 168.8π mi²

2) The area of the sector is 529.9 mi²

2.

1) The area of the sector is 42.3π in²

2) The area of the sector is 132.7 in²

Step-by-step explanation:

The formula of the area of a sector in a circle is A = [tex]\frac{x}{360}[/tex] × π r², where

1.

∵ The central angle subtended by the arc of the circle is 270°

∴ x = 270°

∵ The radius of the circle is 15 mi.

∴ r = 15

→ Substitute them in the formula of the area above

∵ A = [tex]\frac{270}{360}[/tex] × π (15)²

∴ A = 168.75π mi²

→ Round it to the nearest tenth

∴ A = 168.8π mi²

1) The area of the sector is 168.8π mi²

∵ π = 3.14

∴ A = 168.75 × 3.14

∴ A = 529.875 mi²

→ Round it to the nearest tenth

∴ A = 529.9 mi²

2) The area of the sector is 529.9 mi²

2.

∵ The central angle subtended by the arc of the circle is 90°

∴ x = 90°

∵ The radius of the circle is 13 in

∴ r = 13

→ Substitute them in the formula of the area above

∵ A = [tex]\frac{90}{360}[/tex] × π (13)²

∴ A = 42.25π in²

→ Round it to the nearest tenth

∴ A = 42.3π in²

1) The area of the sector is 42.3π in²

∵ π = 3.14

∴ A = 42.25 × 3.14

∴ A = 132.665 in²

→ Round it to the nearest tenth

∴ A = 132.7 in²

2) The area of the sector is 132.7 in²

Answer:

y = [tex]\frac{7}{4}[/tex] x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

7x - 4y = 28 ( subtract 7x from both sides )

- 4y = - 7x + 28 ( divide all terms by - 4 )

y = [tex]\frac{7}{4}[/tex] x - 7 ← in slope- intercept form

Answer:

A=(A+B/2)H

Hope I helped and good luck :)

Answer:

Step-by-step explanation:

Given;

Total people surveyed = 1700 people

Total number of people that owned car = 425 people;

Percentage of people satisfied are those that owned car = 425/1700 * 100

Percentage of people satisfied = 42500/1700

Percentage of people satisfied = 25%

Hence 25% of the people surveyed were satisfied with the​ car

Answer:

y=4/5x+2

Hi! first things first, you want to find the slope. you do that by taking both y values, in this case they are 2 and -6.

then, you need to identify the two 2 x values, 5 and -5.

next, follow this formula: Y2-Y1/X2-X1. y value#2 is -6, and y value#1 is 2. subtract those numbers, to end up with -8. this will go on top of the fraction.  x value#2 is -5, x value#1 is 5. subtract (=-10) and put it on the bottom of the fraction.

now you have your slope! we now have y= -8/-10, or simplified is 4/5.

Now we find the y intercept. to do that, you want to pick a set of points. i'm going to be using (5, 2) because it will be the easiest.

lastly, set up the equation to find the y int: y- y1= m (x- x1)

y- 2= 4/5 (x- 5) = 2

Answer:

she got back 63 times

Step-by-step explanation:

Here, we want to know the number of times she is at bat

from the question, we are made to know that she strikes out twice after 9 times

So striking out 14 times, the number of times she has got back will be ;

14/2 * 9 = 63 times

Answer:

(3,7)

Step-by-step explanation:

Answer:

A. The slope is  [tex]\frac{3}{2}[/tex]

B.  the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point.

Step-by-step explanation:

PART A: Slope

Given tangent line;

[tex]y = \frac{3x}{2} + \frac{9}{2}[/tex]

The slope of the tangent line is equal to the derivative of the function;

[tex]\frac{dy}{dx} =\frac{3}{2}[/tex]

the slope = [tex]\frac{3}{2}[/tex]

PART B: Correct statement that describe the slope of a tangent line:

A secant line is a straight line joining two points on a function and the slope of the function is equal to average rate of change of the function between the two points.

A tangent line is a straight line that touches a function at only one point, and the slope of the function is equal to the instantaneous rate of change of the function at that one point.

Thus, the correct statement is " the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point".

brainlyest plz

Answer:

y-3

Choose a point, any is fine. (I chose point c)

Count how many spaces it to get from point C to where point C' is on the x axis. (It already gave it to us. its 8)

Then count how many spaces it takes to get to C' on the y axis. (In this case you are counting down because A'B'C' is beneath ABC.)

Answer:

2nd One

Step-by-step explanation:

The answer is the 2nd one because it is not a line, and the rest are functions. This line is curved. Non-linear functions mean the graph is not a straight line, which would perfectly describe this one because it starts straight and curves up.

Answer:

$40 and $72, see below :)

Step-by-step explanation:

One way we can do this is to add the total ratios and then divide that from 112.

10x + 18x = 28x = 112

28x = 112

x = 4

That means, for every ratio, you just have to multiply the amount by 4.

so for example, 10 is just 10 * 4 = 40

So, your answer would be you share the money into $40 and $72
