Answer:
yes x=4 is a solution
Step-by-step explanation:
45x = 180
divide each side by 45
45x/45 = 180/45
x = 4
x=4 is a solution
Formula
3p < 14
step 1 : 3p / 3 < 14 / 3
; divide 3p, by 3, and 14 by 3
p is about 4.67 ( rounded, original is 4.66666666666666.... etc)
Multiply both sides by <span>cos</span><span>
</span><span>r<span>cos<span>(θ)</span></span>=<span>sec<span>(θ)</span></span><span>cos<span>(θ)</span></span>=1</span><span>
</span><span>x=r<span>cos<span>(θ)</span></span></span><span>
</span><span>x=1</span>
Answer:
Step-by-step explanation:
We have to find a cubic function of x whose zeros are at x = √7, x = -√7 and at x = -4.
Therefore, the factors of the function will be (x - √7), (x + √7), and (x + 4)
Hence, the equation will be y = (x - √7) (x + √7) (x + 4)
