Answer:
Step-by-step explanation:
Finding the vertex or the end of the shape.
Find the y -intercept, (0,f(0)) ( 0 , f ( 0 ) ) .
Solve f(x)=0 f ( x ) = 0 to find the x coordinates of the x -intercepts if they exist.
Make sure that you've got at least one point to either side of the vertex. ...
Sketch the graph.
To find the hypotenuse of a right triangle you can use the Pythagorean theorem. (a² + b² = c²) Using the measurements provided we can solve like this.
Both a² & b² = 7²
7 x 7 = 49
49 + 49 = 98
Now we need to find the square root of 98 (c²) to get our answer.
9.9 x 9.9 = 98.01 or about 98
The measurements for the tirangle are 7 units, 7 units, and 9.9 units.
Hope this helps!
96 necklaces
You divide the amount of beads total by the amount of beads on each necklace.
( 8160 divided by 85 and 2880 by 30)
12^2 is 144 and 13^2 is 169. 151 is between those two numbers, so the answer is 12 and 13.
Answer:
Option B. $72, because the price of each pack is $8
Step-by-step explanation:
Looking at the double number line we have that
The price of 2 packs of spaghetti is $16
The price of 4 packs of spaghetti is $32
The price of 6 packs of spaghetti is $48
The price of 8 packs of spaghetti is $64
To find out he units rate, divide the price by the number of packs
Find out what is the price of 9 packs of spaghetti
Multiply the unit rate by 9
therefore
The price of 9 spaghetti packs is $72
