Mathematics
1 answer:
sladkih [1.3K]1 year ago
8 0

Step-by-step explanation:

  • in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
  • If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
  • Now let us plug in the value of x=-3
  • y =  - 3( - 3) + 7 \\ y =  - 9 + 7 \\ y =  - 2
  • now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
  • therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.

What is the geometrick mean of 27 and 8 with the pothagereom theorem
enyata [817]

Answer:

x = 6√6

Step-by-step explanation:

27/x = x/8

x² = 27 × 8

x = √(27 × 8)

x = √(9 × 4 × 6)

x = 3 × 2 × √6

x = 6√6

I need help with these two problems. [9 and 10] FORMULAS GIVEN!!
zaharov [31]
<h2>Question 9:</h2>

1. Use Pythagorean Theorem (a²+b²=c²) to solve for missing side of triangle and rectangle. x²+16²=20², or x²+256=400. So, x²=144, and x=12

2. Use formula: 1/2(h)(b1+b2). 1/2 (12) (30+14).

3. Simplify: 1/2 (12) (44)=1/2(528)=264

Area of whole figure is 264 square mm.

<h2>Question 10:</h2>

Literally same thing but with trigonometry.

1. Use sine to find out length of dotted line: sin(60°)=x/12

2: Simplify: 12*sin(60°)=x. x≈10.4 (rounded to the nearest tenth)

3. Use Pythagorean Theorem to find out last leg of triangle: 10.4²+x²=12²

4: Simplify: 108.16 +x²=144. x²=35.84 ≈ 6

5: Use formula: 1/2(h)(b1+b2). 1/2 (10.4) (30+36)

6: Simplify: 1/2 (10.4) (66) =343.2

7: Area of figure is about 343.2

Remember, this is an approximate answer with rounding, so it might not be what your teacher wants. The best thing to do is do it yourself again.

The mass of a tiger at a zoo is 235 kilograms. Randy's cat has a mass of 5,000 grams. How many times greater is the mass of tige
ANTONII [103]
Solutions 

We know that <span>the mass of a tiger at a zoo is 235 kilograms. Randy's cat has a mass of 5,000 grams. To solve the problem we have to convert 235 kilograms into grams. 

</span>235 kilograms = 235000 grams 

<span>Randy's cat has a mass of 5,000 grams 
</span>
Randy's cat = <span>5,000 grams 
</span>
Tiger = <span>235000 grams  
</span>
Our next step is to subtract 5000 from <span>235000 grams  
</span>
235000 grams  - <span>5000 grams = 230000 
</span>
Answer = <span>230000  grams </span>
