Find the radius

Answers

Answer 1

Answer:

The radius is 20 units.

Step-by-step explanation:

(r)^2 + 21^2 = (r+9)^2

r^2 + 441 = r^2 + 18r + 81

360 - 18r = 0

360 = 18r

20 = r

A box has a surface area of 450 cm². Its length and width are 6 and 8 respectively. What is its height?

Answers

Answer:

9.4 cm

Step-by-step explanation:

Given: Box; Length = 6 cm, Width = 8 cm, Surface area = 450 cm²

To Find: Height

Solution:

Divide the volume by the product of the length and width to calculate the height of a rectangular object.

6 × 8 = 48

450 ÷ 48 = 9.4

For this box, the rectangular object has a length of 6 cm, a width of 8 cm, and a volume of 450 cm². The product of 6 and 8 is 48, and 450 divided by 48 results in 9.4.

The height of the object is 9.4cm.

Answers

Answer:

see explanation

Step-by-step explanation:

(a)

The area is calculated as length × breadth

area = 2x(2x + 6) ← distribute

= 4x² + 12x

(b)

area = x(x + 4) ← distribute

= x² + 4x

(c)

shaded area = 4x² + 12x - (x² + 4x)

= 4x² + 12x - x² - 4x ← collect like terms

= 3x² + 8x

Answers

Answer:

Step-by-step explanation:

To use the Elimination method, you must get rid of one pair of variables, so that one side is set to zero. So, in this case, we must get rid of [tex]\displaystyle x,[/tex]therefore we will split the second equation in negative half :

[tex]\displaystyle \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}[y = 4x + 7]}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}y = -2x - 3\frac{1}{2}}} \right. \\ \\ \frac{1}{2}y = -\frac{1}{2}; -1 = y, -2 = x \\ \\ \\ \boxed{[-2, -1]}[/tex]

helpp. Pleasee need answerr

Answers

Answer:

This probaly sounds a little confusing

Step-by-step explanation:

1 day = 10 laps

1 lap = 400 meters

1 km = 1000 meters

12 km = ? days

We can use this information to find out a lot that we don't know.

HOW MANY METERS PER DAY??

In order to find the number of meters in a day, we think, "She ran 400 meters 10 times... 400 times 10... that's 4000 meters in one day."

1 day = 4000 meters (10 x 400 meters)

HOW MANY KILOMETERS PER DAY?

In order to find the number of km in a day, we can think, "One thousand is a kilo. There are 4 'one thousand's in 4000. Kali ran 4 kilometers (literally 4 thousand meters) per day.

1 day = 4 km (4000 m / 1000)

From here you can solve simply by thinking "How many 4km does it take to get to 12km?"

4 x ? = 12

? = 12 / 4

? = 3

Please help, Describe two methods that can be used to find the area of the composite figure.

Answers

A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

Area of the composite figure can be find by using additive areas method and subtractive areas method

What is Composite figure?

Composite geometric figures are made from two or more geometric figures. The composite figure below is made from parts of a rectangle and a circle

Since, Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Area of the composite figure can be find by using two methods,

Additive areas method and Subtractive areas method

In Addictive areas method

Break the composite shape into basic shapes

Find the area of the each basic shapes

Add all the areas of basic shapes together

In Subtractive areas method

Break the composite shape into basic shapes. That shape maybe larger than the composite shapes.

Find the area of the each basic shapes

Area of the composite shape will be the difference between the area of the larger shape.

Hence, the area of the composite figure can be find by using additive areas method and subtractive areas method

How do I solve this arithmetic sequence?

Answers

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82

If p(x)=x^2+x+1 and Q(x)=5x^2-1, find the following

1. Q(4)
2.p(-4)
3.p(1/2)

Answers

Answer: 1. 79

2. 13

3. 7/4

Step-by-step explanation:

Q(x)=5x^2-1

Q(4)=5(4)^2-1

=5(16)-1

=80-1

Q(4) = 79

p(x)=x^2+x+1

p(-4)=(-4)^2+(-4)+1

=16-4+1

p(-4) =13

p(x)=x^2+x+1

p(1/2)=(1/2)^2+(1/2)+1

=1/4+1/2+1

2+4+8/9

=14/8

p(1/2) = 7/4

Complete the table for the given rule.
Rule: y = 52

Answers

~Answer~

Substitute your numbers:

y = 5x

For the first one, y equals 5, so substitute 5 for y.

So, 5 = 5x.

What multiplied by 5 gives 5? The answer is 1.

So, the first one is 1.

Do the same for all the others.

So, 4 = 5x.

4 = 5(4/5)

As a decimal that equals 0.8.

For the last one, I can't tell if that is saying 2 or .2 so I'll do both.

for 2, you will do 2 = 5x and for .2, you will do .2 or 0.2 = 5x.

For 2, it would be 2/5 or 0.4.

For .2 or 0.2, it would be 0.04.

So,

x y

1 5

4/5 or 0.8 4

0.4 if it is 2 and 0.04 if it is 0.2. 2

(looking back, I'm pretty sure it was just 2 and not .2)

I hope this is what u were looking for, if not I'm so sorry for a useless answer. I wasn't completely sure whether I was doing it right since I haven't done these types of math problems in some time.

I need someone to tell me if my first paragraph of my argument paper sounds good. i feel like it sounds weird.my topic is: should poetry be taught more in school?(first paragraph must have: transition, first reason, evidence and explanation 3x in that order)The first reason is that poetry helps express emotions and feelings better and it strengthens overall mental health. A lot of people struggle to talk about their feelings face to face with someone. Sometimes its easier to express your feelings through writing. Poetry allows you to express your feelings and get it all out without having to share those emotions with others. We are similar because we go through the same joys and sorrows, through the same illusions and disappointments. The supreme law of living makes us equals, and to a greater or lesser degree, we all feel euphoria and depression, sadness and happiness, hope and disappointments. (How Does Poetry Communicate Feelings and Emotions?) Not everyone can tell their stories through poetry because they were never taught how to make connections. Through poetry, you can pour all your emotions out onto a piece of paper. Maybe if poetry was taught more in schools, more people would go on into life without bottling up their emotions and going through depression. They would go move on in life knowing they have some way of expressing all their feelings without sharing them with a person. Its never good to sit there and bottle up your emotions. You can take all those bottled-up emotions and write them down using several types of poetry. A well-crafted phrase or two in a poem can help us see an experience in an entirely new way. We can gain insight that had evaded us many times, that gives us new understanding and strength. (Five Reasons Why We Need Poetry in Schools) The brain processes poetry a lot like music. A lot of people use music to express themselves or make themselves happier when theyre upset. (Poetry Lights Up the Brain) MRIs have shown that both art forms stimulate regions in the brains right hemisphere that are linked to reward and emotion. So even when reading poetry, you can start to feel better. So many people can understand the way others feel. Reading certain poetry can make you feel included and not so alone. 1.
