Answer:

33

Step-by-step explanation:

b² - 4ac, where a = -3, b = 3 and c = 2

= (3)² - 4(-3)(2)

= 9 + 24

= 33

Answer:

33

Step-by-step explanation:

Sub all the values as they are

(3)^2 - 4(-3)(2)

9 + 12(2)

9 + 24

Hence...Ans = 33

Top soil is sold by the cubic yard. How much top soil, to the nearest cubic yard, is needed to create a flower bed with soil 4 f
Montano1993 [528]
You find the volume of the flower bed (4 times 25 time 6) this is 600. but you then realize that you need to convert the 6 inches into ft. so you do 25 times 4 /2 which is 50. 50/9 is rounded up to 6. Just notes: Although, when you do this, your units are in ft squared. you need to get them into yards. there are 3 feet in one yard. So, divide 600 by 9. (you need to multiply 3 times 3 to cancel out the ft squared). your answer is a

Find the measure of the angle x to the nearest tenth. Question 7 options: 33. 5° 56. 5° 28. 9° 44. 3°.
Nina [5.8K]

The question is an illustration of right-angled triangles

The approximated value of x is 33.5 degrees

The given parameters are:

\theta = x

Hypotenuse = 58

Opposite = 32

To determine the measure of angle x, we simply make use of the following sine ratio.

\sin(\theta) = \frac{Opposite}{Hypotenuse}

So, we have:

\sin(x) = \frac{32}{58}

\sin(x) = 0.5517

Take arc sine of both sides

x = \sin^{-1}(0.5517)

This gives

x = 33.5

Hence, the approximated value of x is 33.5 degrees

Someone please help me in this question it is kind of confusing it is a question under pre calculus in first year calculus i wil

Neither P, nor A are on the sketch 
I guess P is the upper right corner of the rectangle 
and A=(0,1) 

P belongs to the line going through (1,0) and B(0,y) 
<span>but we don't know the y-coordinate of B </span>

<span>the triangle is right and isosceles, so pythagoras a²+a²=2² ... 2a²=4 ... a²=2 ... a=sqrt2 </span>
now look at the right triangle BOA 
<span>his hypotenuse is AB=sqrt2 and the <span>the kathete</span> OA is 1 </span>
so y²+1²=(sqrt2)² ... y²+1=2 ... y²=1.. y=1 
so the coordinates of B are (0,1) 

the line going through (1,0) and (0,1) is L(x)=-x+1 

P belongs to this line, so the coordinates of P are P(x,-x+1) (0<x<1) 

b) so if that's P, the height of the rectangle is -x+1 and the width=2x 
<span>so its area A(x)=2x*(-x+1)= -2x²+2x 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
