Answer:

false

Step-by-step explanation:

as a guy who studied calculus, a lot of things were done that are just mathematically incorrect. for instance,

infinity - infinity is not 0.

0÷0 is undefined. so you cant just equate it to ( 2 × infinity)

to sum up this proof is entirely false.

GCF is the highest value that can divide an expression. The equivalent expression to  10x^2y + 25x^2 is 5x^2 (2y + 5)

GCF is the highest value that can divide an expression. Given the expression below

10x^2y + 25x^2

Find the factor of each

10x^2y = 5 * 2 * x^2 * y

25x^2 = 5 * 5 * x^2

Since 5x^2 is common to both factors, hence

10x^2y + 25x^2 = 5x^2 (2y + 5)

The equivalent expression to  10x^2y + 25x^2 is 5x^2 (2y + 5)

Answer:c x=13

Step-by-step explanation:

straight line =180

180-50=130

7x+3x=10x

130/10=13

So the answer is x=13

Answer:

4. y = |x| + 2

Step-by-step explanation:

"g(x) = |x| + k" means that f(x) will be translated however many units up or down depending on k. If k is positive, the graph will translate up. If k is negative, the graph will translate down. Because we need to translate up, the value of k needs to be positive. The best answer choice is choice 4, y = |x| + 2.

We can eliminate choices 1 and 2 because the way the equations are set up are for the horizontal translations.

g(x) = |x - h| are for horizontal translations.

g(x) = |x| + k are for vertical translations.

The third choice is wrong as well because k is negative, not positive.

Answer:

x = 5

Step-by-step explanation:

using the sine or cosine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2x = 10 ( divide both sides by 2 )

x = 5

Here is why:

Correct choice is D.

Answer:

Hanna

Step-by-step explanation:

In order to find out how fast Thomas has drove as compared to Hanma we have to compare the speed of each other,

Speed of Hanna = 50mph (as given in ur question)

Speed of Thomas

Since the unit of time of the distance traveled by Thomas is not same as that of Hanna we have to convert the minutes into hour,

Distance traveled = 12miles

Time taken = 15minutes

Speed = 12miles/15mim

Converting minutes into hours we have to multiply by a number whose product will be 60 and that will 4

that is 15 times 4 is 60. But to make the ratio equal

we have to multiply the distance too by 4.

= 12*4/15*4

=48 miles/60minutes

=48miles/1hour

=48mph

Comparing both speeds

Speed of Hanna compared to Speed of Thomas,

50mph > 48mph

Hence, Hanna has the faster speed.

the formula for gradient is difference in y divided by difference in x . therefore

10-4 divided by 6 - 3 equals to 6 divided by 3 = 2

the gradient is 2

1.) The measure of each angle of  ABC is equal to the corresponding angle of  A'B'C' , the measures of this angle is preserved when you rotate the triangle.

2.) It was clear that triangle A'B'C' is dilated form ABC, meaning the angles will be the same.

3.) The rules for dilation only change the length of the triangle not the angles.

Answer:

9

Step-by-step explanation:

let's assume ;

12=a

15=c

?=b

so;

a2+b2=c2

(12)2+b2=(15)2

144+b2=225

b2=225-144

b2=81 (square root both sides)

You'll get

b=9

NB; 2 is used as squared

From the calculations, the volume of the sculpture is 27 times the volume of the model.

The volume of a cube is obtained using the formula;

Volume = l^3

Where l is the length of each edge. We should note that the lengths of all the edges in a cube are equal.

Hence,

volume of the model = (25)^3 = 15625 in^3

volume of the sculpture = (3 * 25)^3 = 421875  in^3

Ratio of the volume of the sculpture to the volume of the model = 421875  in^3/15625 in^3

= 27:1

Hence, the volume of the sculpture is 27 times the volume of the model.

The most likely next step in the series is 5 rows with 4 dots in each row and 4 columns.

Option C is the correct answer.

A series of patterns is a sequence of recurring designs or motifs that follow a particular order or progression.

Patterns can be found in many different fields, such as mathematics, science, art, and literature.

We have,

From the series of patterns,

We see that,
