Answer:

It's pretty simple

Step-by-step explanation:

First divide 18 and 3 = 6

then divide 30 by 6 = 5

7 multiplied by 6 = 42

Then divide 48 divided by 6 = 8

10 multiplied 6 = 60

hope this works!

60°=10

SO right angle 90°=15

Answer:

x= -5

Step-by-step explanation:

f(x)  =  [ x^2  -  25 ] / [ x + 5 ]  =  [ (x + 5) ( x- 5)]  / [ x + 5 ]  =  x - 5

This will be the graph of  f(x) =   x - 5  with a  "hole"  at   x  =  - 5

The graph of the rational function f(x) = (x² - 25)/(x + 5) is represented by the graph second option (B) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The equation of the rational function:

f(x) = (x² - 25)/(x + 5)

As we know, in the rational function the denominator cannot be zero.

x + 5 ≠ 0

x ≠ -5 (there will be a hole at x = -5)

f(x) = (x - 5)(x + 5)/(x + 5)

Because: a² - b² = (a - b)(a + b)

f(x) = (x - 5)

The above function represents the linear function.

The slope of the linear function is positive.

m = 1

The y-intercept of the linear function is c = -5

Thus, the graph of the rational function f(x) = (x² - 25)/(x + 5) is represented by the graph second option (B) is correct.

Step-by-step explanation:

y = -50x -100

When x= 0, plug in 0 to x.

y = -50(0) -100

= 0 - 100

= -100

So in the first y box, you would put -100

I can't tell what the number is in bottom right box so i don't know what x is going to be

Answer:

3,848 feet.

Step-by-step explanation:

1) Square 70

2) Multiply 4,900 (the square of 70) by pi

3) Divide 15,393.804 (4,900 times pi) by 4 (to find a quarter of the tank)

4) Round 3,848.451 (15,393.804 divided by 4) to the nearest whole number and you get 3,848 feet.

Answer:

Step-by-step explanation:

The material Nabil need in order to make the second prism is 87.5

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.

So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.

So area of first figure = k² × area of second figure

Similarly,

Volume of first figure = k³ × volume of second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

We are given that;

Volume of material= 1000 cm³

Volume of prism= 8.7 cm³

Now,

Find the volume of the first prism using the formula: V = (1/2)bhℓ1, where b is the base, h is the height of the triangle, and ℓ is the length of the prism. Plug in the given values: V = (1/2)(8.7)(8.7)(10) = 378.45 cm³

Find the volume of the second prism using the same formula, but multiply each dimension by 5 since it is a dilation with a scale factor of 5: V = (1/2)(5b)(5h)(5ℓ) = (1/2)(43.5)(43.5)(50) = 46593.75 cm³

Subtract the volume of material he has from the volume of material he needs for both prisms: 1000 - (378.45 + 46593.75) = -45972.2 cm³

Since he needs more material than he has, he needs to get more material with a volume equal to | -45972.2 | cm³ or 45972.2 cm³.

Therefore, by dilation the answer will be 87.5

Answer:

y=-2x

Step-by-step explanation:

if x<-5

x+5<0

x-5 also<0

so

|x-5|=-(x-5)=-x+5

|x+5|=-(x+5)=-x-5

Hence

y=-x+5-x-5

or

y=-2x,if x<-5

Answer:

-37

Step-by-step explanation:

for the first equation to equal 4 the x must equal -6.

because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.

So now plug -6 into the new problem so now it is

5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!

Answer:

I have a parrot

I have an African grey parrot, his name is Yaco (pronounce the "a" in his name the same way you'd pronounce the "a" in taco lol). He's 23 years old and the species can normally live in the range of 50-85 years old! Yes! He does do things on his own, eat, drink, play, and talk. One question you asked is "Does he ever steal food?" No, but he's worse than the dog when it comes to begging for human foods and snacks, he can have quite a vary of human foods such as some fruits, nuts, and crackers and such. Also, he has about a 300 word vocabulary and with a wide range of different sounds and noises. And with him being a parrot, he's picked up all these words, phrases, and sounds from people and movies and pets that are always often around him and in our home. He has been around 7 years longer than me. He's a very neet and VERY smart bird. In your free time go onto you.tube and search up 'Einstein the talking african grey parrot' it'll give you an idea of their intelligence.
