Answer:

See explanations below

Step-by-step explanation:

Given the quadratic formula that expresses the temperature of a chemical reaction

C(t)=-12t² +8t +93

Given that C(t) = 110°, we are to find the value of t

Substitute

110 = -12t² +8t +93

-12t² +8t +93-110 = 0

-12t² +8t -17 = 0

12t² -8t + 17 = 0

Using the general formula;

t = -(-8)±√(-8)²-4(12)(17)/2(12)

t = 8±√64-816/24

t = 8±√-752/24

<em>Since the value of t will give a complex number, hence the time doesn't exist when the reaction reaches 110°C</em>

If cos(θ)=2853 with θin Q IV, what is sin(θ)?

marysya [2.9K]

Answer: $\sin \theta=\frac{-45}{53}$

Step-by-step explanation:

Since we have given that

$\cos\theta=\frac{28}{53}$

And we know that θ is in the Fourth Quadrant.

So, Except cosθ and sec θ, all trigonometric ratios will be negative.

As we know the "Trigonometric Identity":

$\cos^2\theta+\sin^2\theta=1\\\\\sin \theta=\sqrt{1-\cos^2\theta}\\\\\sin \theta=\sqrt{1-(\frac{28}{53})^2}=\sqrt{\frac{53^2-28^2}{53^2}}\\\\\sin \theta=\sqrt{\frac{2025}{53^2}}\\\\\sin \theta=\frac{45}{53}$

It must be negative due to its presence in Fourth quadrant.

Hence, $\sin \theta=\frac{-45}{53}$

Drag each number to show whether it is equal to 90 percent, 90/100,or neither

victus00 [196]

9%= 9/100
9/10= 90%
.9= 90%
90/10= other
.9%= other
.09= 9/100
