Solve the equation for all real solutions in simplest form.
3z^2+17z+16=0
Answers
Answer:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Plug in and solve:
[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]
and
[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]

Simplify (use only positive exponents) : (3y^10)(2y^2)/8y^5
please explain how you did it so that I can understand what I'm doing <3
Answers
So;
(3y^10)(2y^2) is equal to (3)(2)(y^10+2).
6y^12/8y^5
When dividing exponents, you do the opposite and subtract the exponents. And you divide the whole number by half.
6y^12/8y^5 = 3y^7/4

Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).

y = 8x + 12
If x = -6, y = _____
If y = 13, x = _____
Answers
if x = -6
y = 8(-6) + 12
y = -48 + 12
y = - 36
if y = 13
13 = 8x + 12
13-12 = 8x
8x = 1
x = ¹/₈ ≈ 0.125
Answer:
If x = -6, y = -36
If y = 13, x = [tex]\frac{1}{8}[/tex]
Step-by-step explanation:
There is one equation and are asked to find x and y if there is a certain value to substitute either x or y.
Let's start with x, we know that x = -6. Meaning that we need to subtitute x for -6. Do as followed :
y = 8(-6) + 12
y = -48 + 12
y = -36
Now do y, we know that y is 13. Meaning that we need to substitute y for 13. Do as followed :
8x + 12 = 13
We need to isolate x alone, so do as followed :
Subtract 12 from both sides to get 8x alone :
8x = 1
Divide 8 from both sides to get x alone :
x = 1/8

Submit Question
Answers
If y = A sin(x) + B cos(x), then
y' = A cos(x) - B sin(x)
y'' = -A sin(x) - B cos(x)
Substitute these into the ODE:
4y'' + y' + 5y = 2 cos(x)
4 (-A sin(x) - B cos(x)) + (A cos(x) - B sin(x)) + 5(A sin(x) + B cos(x)) = 2 cos(x)
(-4A - B + 5A) sin(x) + (-4B + A + 5B) cos(x) = 2 cos(x)
(A - B) sin(x) + (A + B) cos(x) = 2 cos(x)
Then
A - B = 0
A + B = 2
Adding these equation gives
(A - B) + (A + B) = 0 + 2
2A = 2
A = 1 → B = 1

Density is the amount of mass in a certain volume. Density is recorded in units of grams per milliliter
(g/mL). What is the density of an object is its mass 100g and its volume is 50mL?
a 0.5 g/mL
b 2 g/mL
c 50 g/mL
d 5,000 g/mL
Answers
Answer:
Density = mass/volume
Density = 100g/50mL
Density = 2g/mL, so b is correct
Let me know if this helps!
Answer:
b. 2 g/ml
Step-by-step explanation:
As we know density is defined as mass per unit volume so here
Density is recorded in units of grams per milliliter
So Now
Mass (m) = 100 g
Volume (V) = 50 ml
Density (d)
= m/v
= 100 / 50
= 2 g /ml
