Answer: 13

Step-by-step explanation: In the picture, you have angle H congruent to angle N, Side MN congruent to side GH, and angle G congruent to angle M. That means that these two triangles are congruent by ASA. Therefore by CPCTC, side GI is congruent to side MO, which means that MO is 13.

The answer to this is 13

For the function below, (a) find the vertex; (b) find the axis of symmetry; (c) determine whether there is a maximum or a
minimum value and find that value; and (d) graph the function.
f(x) = -x2 - 6x-4

Answers

Answer:

Step-by-step explanation:

f(x) = ax² + bx + c

"x" coordinate of vertex is ( - [tex]\frac{b}{2a}[/tex] )

axis of symmetry is x = - [tex]\frac{b}{2a}[/tex]

If a > 0 the function opens upward and has minimum value.

If a < 0 the function opens downward and has maximum value.

f(x) = - x² - 6x - 4

(a). x = - [tex]\frac{-6}{-2}[/tex] = - 3 ; y = - (- 3)² - 6( - 3) - 4 = 5

Coordinates of vertex are (- 3, 5)

(b). The axis of symmetry is x = - 3

(c). The given function opens downward

y = 5 is a maximum of a given function.

An iron rod of length 25cm weighs 196.5g.What will be the weight of an iron rod of length 1.6m?

Answers

Answer:

1257.6 g

Step-by-step explanation:

1 m = 100 cm

1.6 m = 1.6 * 100 cm = 160 cm

Use a proportion.

196.5/25 = x/160

25x = 196.5 * 160

25x = 31,440

x = 1,257.6

The figure below is made up of a square with height, h, units and a right triangle with height, h units, and a base length, b units.

The area of this figure is 80 square units.


Write an equation for the area of the shape below.

Answers

Answer:

Step-by-step explanation:

A = 12 × 16 + (1/2)(12 + 8)(10) = 292 units²

The Equation for Area of figure is area of Figure, h² + 1/2(h)(b) = 80

What is Area?

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given:

We have the figure consist of one rectangle and one right triangle.

Now, Area of Figure,

=Area of rectangle + area of Triangle

= length x width + / x base x height

=  16 x 12 + 1/2 x 10 x 20

= 192+ 100

=292 unit²

and, if the square with height, h, units and a right triangle with height, h units, and a base length, b units.

Then, area of Figure= h² + 1/2(h)(b) = 80 square units.

Explain the rules for multiplication and division to convert units. How do you know when to multiply and when to divide to convert units of measurements

Answers

Answer:

The basic rule is: If you need to convert from a larger unit to a smaller unit, multiply. If you need to convert from a smaller unit to a larger unit, divide. You will make the number smaller and, as you already know, division is all about making numbers smaller.

Answer:

addiemoss23/this person wrote this NOT me, it is right btw

Step-by-step explanation:

To convert units into smaller units, multiply. When the units are smaller , you need more of them to express the same measure. To convert smaller units to larger units, divide. When the units are larger , you need fewer of them to express the same measure.

Look at where the line intersects with the other line perfectly and find the two closest times when that happens, then go up and over and count it.

So for the first one it is: up 1 over 1. That as a fraction is, 1/1 and that equals 1. So the slope is 1.

For the second one it is up 1 over 2. That as a fraction is 1/2. So the slope is 1/2.

You have quarters. You find ​% more quarters in your room. Then you go shopping and spend ​% of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping.​ Calculate, in​ dollars, the amount of money you have left.

Answers

Complete question :

You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.

A. Write an expression that represents the total number of quarters you take with you when you go shopping.

B. How much money do you have left?

Answer:

[20 + (0.4*20)] = 28 quarters

$3.5

Step-by-step explanation:

Given that:

Initial number of quarters = 20

Quarters in room = 40%

Hence, Numbe of quarters in room = 0.4 * 20 = 8

Total number of quarters taken for shopping :

(Initial amount + Numbe of quarters in room)

(20 + 8) = 28 quarters

50% of quarters was spent on shopping :

0.5 * 28 = 14 quarters

Total left :

28 - 14 = 14

Quarters left in dollars :

1 quarter = 25 cent = 0.25 dollars

14 * $0.25 = $3.5

Find the equation of the line that passes through (1,-1) and is parallel to 2x+y−3=0.
Leave your answer in the form y=mx+c

Answers

Answer: y= -2x + 1

Step-by-step explanation:

We can formulate the slope equation of that line by

S= Y-Y1/X-X1

By the given statement "parallel", the slope of the function "y=3-2x" shall then equals the first line -->1

to conclude, we will use the first point at x=1 ( Like the given point of the line) and additional point at x=0...

y(1)=3-2(1)=1, Hence, (1,1)

y(0)=3-2(0)=3, Hence, (0,3)

By the fact 1

then we shall conclude with simple linear equation as follow

m=y2-y1/x2-x1 = 1-3/1-0=-2

The general formula of the Required function is y=mx+c

In fact the line passes through the point (1,-1)

Hence y in x=1 equals -1

-1= -2(1)+C

C= -1+2=1

Then FINALLY the line formula isy= -2x + 1

the diagram shows a circle inside a square ABCDB AB = 20 cm. the radius of the circle is 9 cm. work out the area of the shaded region

Answers

Step-by-step explanation:

Area of the square = a²

= 20²

= 400cm²

Area of the circle = πr²

= 22/7 × 9²

= 22/7 × 81

= 254.57cm²

Area of the shaded region = Area of the square - Area of the circle

= 400cm² - 254.57cm²

= 145.43cm²

Answers

Answer:

y = 130

Step-by-step explanation:

Those two exterior angles are equal (property of parallel lines)

y is thsupplement of 4x - 14

2x + 18 = 4x - 14                     Add 14 to both sides

2x + 18 + 14 = 4x - 14 + 14      Combine like terms

2x + 32 = 4x                           Subtract 2x from both sides

2x-2x+32=42-2x                    Combine

32 = 2x                                   Divide by 2

32/2 = x

16 = x

Write an equation of a line that has a slope of -2 and passes through the point (1,4)

Answers

Answer:

y = -2x + 6

Step-by-step explanation:

Since we already have the slope we just need to find the y-intercept.

To do that just plug in the point you were given. (1,4)

4 = -2(1) + b (b represents the y-intercept)

4 = -2 + b (add 2 on both sides)

6 = b

y = -2x + 6 is the equation

Hope this helps!!

Answer:

The equation (in y=mx+b form) would be y= -2x+6

Step-by-step explanation:

The slope is given from the start, which is -2, so you would plug that in for m to make the equation y=-2x but this IS NOT YOUR ANSWER

I was able to graph it, although there are multiple ways to do this.

Next you have to find the y-intercept. You use your coordinate (1,4) and go up twice (positive) (1,6) and go to the left (negative) to get the point (0,6) giving you your intercept.

Plugging it into the equation for b, your equation would now be y= -2x + 6 giving you your final answer

The little mermaid wants to save the life of the drowning human prince in the ocean. C. The little mermaid is worried that the prince will reach her fathers palace before her. D. The little mermaid is in a hurry to get to her fathers palace and escape the shipwreck. The Little Mermaid by Hans Christian Andersen (excerpt)The little mermaid now perceived that the crew was in danger; even she was obliged to be careful, to avoid the beams and planks of the wreck which lay scattered on the water. At one moment it was pitch dark so that she could not see a single object, but when a flash of lightning came it revealed the whole scene; she could see everyone who had been on board except the prince. When the ship parted, she had seen him sink into the deep waves, and she was glad, for she thought he would now be with her. Then she remembered that human beings could not live in the water, so that when he got down to her father's palace he would certainly be quite dead.No, he must not die! So she swam about among the beams and planks which strewed the surface of the sea, forgetting that they could crush her to pieces. Diving deep under the dark waters, rising and falling with the waves, she at length managed to reach the young prince, who was fast losing the power to swim in that stormy sea. His limbs were failing him, his beautiful eyes were closed, and he would have died had not the little mermaid come to his assistance. She held his head above the water and let the waves carry them where they would.
