Answer:
12. C
13. B
14. B
Step-by-step explanation:
12 - length of ramp = hypotenuse
given the angle 20, we have hypotenuse and opposite, so we use sin
sin 20* = 10/r
13- tan 46 = x/11, x = 11(tan46) = 11.4
14- cos 46 = 12/x = 17.3
I think you're trying to say 6x^6-4x^5+9x-6. ^ Is a symbol that means the number after it is an exponent.
First step, find the gcf (greatest common factor) between the first two parts. The gcf of 6x^6-4x^5 is 2x^5.
Now take it out. You get
2x^5(3x-2)
If you expand that equation, you will get 6x^6-4x^5 which is why you know it's correct.
Now do the same for the second half.
The gcf for the second two parts is 3.
3(3x-2)
Notice anything? Yep, in both of them, after you take out the gcf, you get (3x-2)
Now, you combine them into one equation
2x^5(3x-2)+3(3x-2)
Then you do this
(2x^5+3)(3x-2)
That's your factored form.
Answer: 46
Step-by-step explanation:
Yes !!
So the first thing to do is to simplify both sides of this equation:
<span>12.46x+4.5</span>=162
Next we shall subtract 4.5 from both sides so:
<span>12.46x+4.5−4.5</span>=<span>162−4.5</span>12.46x=<span>157.5
</span>Now that we are done with all those steps now here is the final steps so now we shall divide both sides by 12.46:
<span><span><span>12.46x/</span>12.46 </span>= <span>157.5/<span><span>12.46
</span>Ok so your final answer shall be:
</span></span></span>x=<span>12.640449
</span>I hope this helps you greatly!
A^2 + 5^2 = 10^2
a^2 + 25 = 100
a^2 = 100-25
a^2 = 75
a = sqrt(75) = 5sqrt(3)
answer is A
