Find the missing side of the triangle.

Mathematics

1 answer:

Ronch [10]3 years ago

6 0

Answer:

x=1

Step-by-step explanation:

Since you know two sides and are trying to find the missing side, you can use the Pythagorean Theorem. So fashion the equation like this:

x^2 + 3^2 = sqrt10^2. After simplify, which leads to x^2 + 9 =10. Then have the variable to one side by subtracting 9 on both sides. This leads to x^2=1. Finally, square root both sides which leads to 1. Note that any root of 1 is 1. So your answer becomes x=1.

Hope this helps!

Freddy has a shelf that is 72 over 5 inches wide. How many catalogs can Freddy arrange on the shelf if each catalog is 4 over 5

andrew-mc [135]

<h2>Answer:</h2>

Option: D is the correct answer.

D: 18, because the number of catalogs is 72 over 5 divided by 4 over 5.

<h2>Step-by-step explanation:</h2>

Let Freddy could arrange n catalogs on the shelf.

The dimension of the shelf is:

72 over 5 inches wide.

The dimension of the catalog is:

4 over 5 of an inch thick.

n × Dimension of one catalog=Dimension of shelf.

i.e.

n×(4 over 5 inches)=72 over 5 inches

i.e.

n=72 over 5 inches/ 4 over 5 inches

i.e.

n=72/4

i.e.

n=18

Hence, Freddy could arrange 18 books in the shelf.

The grid shows figure Q and its image figure Q’ after a transformation. Which transformation was applied on figure Q?

photoshop1234 [79]

Answer:

B.) Clockwise rotation of 90° about the origin.

Step-by-step explanation:

We see that the co-ordinates of the figure Q are (2,4), (3,7), (7,5), (5,4) and (4,2).

It can be seen that the co-ordinates changed after the transformation are (4,-2), (7,-3), (5,-7), (4,-5) and (2,-4).

That is,

Q Q'

(2,4) ---------------------> (4,-2)

(3,7) ----------------------> (7,-3)

(7,5) ----------------------> (5,-7)

(5,4) ----------------------> (4,-5)

(4,2) ----------------------> (2,-4)

Thus, the co-ordinates are changing by the rule (x,y) → (y,-x).

Hence, the transformation applied is 'Clockwise rotation of 90° about the origin'.

So, option B is correct.

How to find the discriminant of

Sonbull [250]

the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0

13x^2-16x = x^2 -x

we need to get in it the standard form

subtract x^2 from each side

12x^2 -16x = -x

add x to each side

12x^2 -15x = 0

12x^2 -15x -0 =0

a=12 b=-15 c=0

b^2 -4ac

the discriminant = b^2

b^2 = (-15)2 = 225
