Answer:
the ladder reaches up to 9.75 ft. high
Step-by-step explanation:
a^2+b^2=c^2
plug in the numbers
a^2+49=144
then subtract 49 from 144
a^2=95
then sq 95
a=9.75
Answer:
-1
Step-by-step explanation:
Answer: Domain: 0,1,2,3 and 4 and Range: 1,2,4,8 and 4
Step-by-step explanation:
The domain is the set of all inputs that makes the function definable. As we see the function looks like an exponential function which means the domain is all real numbers.
So the inputs are 0,1,2,3 and 4
the outputs are 1,2,4,8 and 4
Step-by-step explanation:
1. C:arithmetic, 34, 39, 44
2. B: geometric, -64, 128, -256
3. C: geometric, 1, 1/3, 1/9
If we have 2 more blue pens than black pens, our blue pens can be rewritten as blue = 2 + black. Now we can set up an equation. Originally this equation would involve both blue and black, but since we only have 1 equation to set up, we can only have 1 unknown. That's why we base the number of blue pens on the number of black pens and do a substitution. So instead of blue + black = 94, we have (black + 2) + black = 94. That simplifies to 2 black + 2 = 94, and 2 black = 92. Now if we divide by 2, we get that the number of black pens is 46. If we have 2 more blue than black, the number of blue pens we have is 48. 46 + 48 = 94, so there you go!
