Are you taking the quiz for math 1? This bout to be real awkward if you aren't who I think you are :/
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
Alright, so in this you want to use the slope formula: m=y2-y1/x2-x1. You plug the coordinates of the points into the formula to get the slope. (x1,y1) (x2,y2). So in this problem, 7 is x1, -1 is y1, -2 is x2, -4 is y2. So using the formula, you plug in y2 minus y1, divided by x2 minus x1.
So m (the slope) = -4- (-1) divided by -2-7.
2 negatives make a positive, so -4 + 1 is -3. -2-7 becomes -9. So this is now -3/-9. Again, 2 negatives make a positive, so this is now 3/9. Simplify and the answer is positive 1/3. Hope this helps!
Answer:
0.624999999(repeating) so i would round it to 0.625 or 0.63 (both work and are rounded, its really up to wherever your teacher wants you to round it to if they want you to round it)
Step-by-step explanation:
2/3 x 1/2 (3/4 ÷ 2/5)=
simplify the parentheses (3/4 ÷ 2/5) to 1.875
2/3 x 1/2 x 1.875=
simplify 2/3 x 1/2 to 0.333333(repeating)
0.3333333333 x 1.875 = 0.6249999999(repeating)
round it to 0.625 or 0.63 (which ever one your teacher wants you to round it to)
Find the GCF. Which is 4. Pull it out and simplify the remaining terms.
4(5+6g)
Answer:
9.2 seconds.
Step-by-step explanation:
We have been given an equation that represents dive of a bird as 
, where x represents the time the dive lasted in seconds and y represents the height of the bird in meters.
We can see that our given equation is a parabola. The leading coefficient is positive, so our parabola will be an upward opening parabola.
Upon graphing our given equation, we will get our required graph as shown in the attachment.
As x represents the time the dive lasted in seconds and y represents the height of the bird in meters, so the bird will be at the surface when the graph will cross x-axis.
We can see that graph crosses x-axis at 
.
Upon rounding to nearest tenth, we will get:
.
At 
the bird dives in water and goes down the water surface and at 
the bird comes to the surface, therefore, the bird will be at surface after 9.2 seconds.
