Answer:
[tex]-y\sqrt{3}[/tex]
Step-by-step explanation:
Under the radical there is a perfect square, one can take the perfect square out, and write it by its square root. The result of taking the principal square root is always positive, but it is given that the perfect square factor is negative, thus, one must multiply the square root by the negative sign to ensure that the result is positive.
Answer:
[tex]-y\sqrt{3}[/tex]

Write the equation in standard form of the line that
passes through the point (4, -2) and has a slope of -1/2.
Answer:
x+2y=0
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-1/2(x-4)
y+2=-1/2x+4/2
y+2=-1/2x+2
y-(-1/2x)=2-2
y+1/2x=0
1/2x+y=0
2(1/2x+y)=2(0)

Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation? Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation?
Answer: [tex]6+\sqrt{21}\ \text{and}\ 6-\sqrt{21}[/tex]
Step-by-step explanation:
Given
Quadratic equation is
[tex]x^2-12x+15=0[/tex]
Solving by completing the square method
[tex]\Rightarrow x^2-2\cdot 6\cdot x+15=0\\\text{add and subtract 36}\\\Rightarrow x^2-2\cdot 6\cdot x+15+36-36=0\\\Rightarrow x^2-2\cdot 6\cdot x+36+(-36+15)=0\\\text{using}\ (a-b)^2=a^2+b^2-2ab\\\Rightarrow (x-6)^2-21=0\\\Rightarrow (x-6)^2=21\\\Rightarrow x-6=\pm \sqrt{21}\\\Rightarrow x=6\pm \sqrt{21}[/tex]
The solution set of the equation is [tex]6+\sqrt{21}\ \text{and}\ 6-\sqrt{21}[/tex]

Three less than a number is 14 more than 2 times that number. What is the number?
Answer:
-20 = - 20
Step-by-step explanation:
Suppose the number is x
three less than a number means x - 3 which is equal to 14 more than twice a number means 2x +14.
So we can write
x - 3 = 2x +14 - - - - - A
subtract x from both sides
x - x - 3 = 2x - x +14
-3 = x +14
Subtract 14 from both sides
-3 - 14 = x +14 - 14
-17 = x
Or x = - 17
Now can verify our answer by putting the value of x in Eq A
-17 - 3 = 2 x (-17) +14
-20 = - 34 +14
-20 = - 20
I hope this helps. :)

Taylor noticed that for the rectangle below she could multiply 2 times 3 to get its area of 6 square inches. How else could she find the area?
Answer:
Add 2+2+3+3
Step-by-step explanation:
Correct me if i'm wrong but that's my answer. I studied this 3 years ago.
Answer:
3 x 2 or 3 + 3
Given: Taylor noticed the rectangle she could multiply 2 times 3 to get its area of 6 square inches.
so, if we did 3 times 2 its 6 but if we did 3 + 3 it also 6 so therefore she could do 3 x 2 or 3 + 3 to find the area.

Step-by-step explanation:
Hey There! Allow me to explain how to solve this (I will not say the answer bc I also don't know but here is how you can find it). As you see the shape is a Cyclinder & the formula for it is V=Bh or V=πr2h. You might wanna start with solving the problems (8x - 4) & (11x + 12) Use the order of PEMDAS (Parrenthesis, Exponets, Multiplication, Division, Addition, Subtraction.) to solve is so if solving (8x - 4) And if x = 8 than first begin with mutiliplying 8 x 8 (Because it says 8x and x = 8 which means we are multiplying) than subtract that with 4 (Which will be 64 - 4). Than for (11x + 12) you will wanna do 11 x 8 which is 88 added by 12 which that will be 100. Than use the formula (V=Bh or V=πr2h) And you should have you're answer! I hoped this help and sorry for not finding the answer but atleast I explained to you on how to solve it! <3

The half-life of radium is 1690 years. If 90 grams are present now, how much will be present in 400 years?
Answer:
76.38 g
Step-by-step explanation:
Below expresion can be used in calculating the remaining amount of radium
A(t)=A(0) (1/2)^(t/h)
Let A(t)=the remaining amount of radium
Let A(0)= amount of radium at the beginning= 90 grams
t= amount of time in years= 400 years
h=the half-life time= 1690 years
A(t)=A(0) (1/2)^(t/h)
If we substitute the values into the expresion we have
A(t) = 90 × (1/2)^(400/1690)
A(t)= 76.38 g
Help me plz!!!! For number 17
Answer:
x=40
Step-by-step explanation:
x + 320 = 360
-320 -320
x = 40
Answer:
x=40
Step-by-step explanation:
So, since the figure has 4 sides, we know that the sum of the interior angles is 360. To check: (n-2)*180=(4-2)*180=28180=360.
That means x equals 360 minus the sum of the other three angles.
100+120+100=320
360-320=40
x=40 degrees

Answer:
the solution to that is 26.
Answer:
26
Step-by-step explanation:
Substitute x = - 6 into the expression
x² + x - 4
= (- 6)² + (- 6) - 4
= 36 - 6 - 4
= 30 - 4

3 people invest in a business in the ratio 2:3:5.if the profit from the business is $450 000.how much does each person get?
Answer:
$90,000;$135,000;$225,000Step-by-step explanation:
In this question we have to find the share of each person
First we have to find the sum of all the ratios,
[tex]2 + 3 + 5 \\ = 10[/tex]
Then we have to represent their share as a fraction and then multiply it by the total value,
The share of first person:-
[tex] \frac{2}{10} \times 450000 \\ = 2 \times 45000 \\ = 90000[/tex]
So the first person share is $90,000
The share of second person:-
[tex] \frac{3}{10} \times 450000 \\ = 3 \times 45000 \\ = 135000[/tex]
So the second person share is $135,000
The share of third person:-
[tex] = 450000 - (135000 + 90000) \\ = 450000 - 225000 \\ = 225000[/tex]
So the third person share is $225,000
(This is your answer hope it helps :))

Answer:
∠ V = 130°
Step-by-step explanation:
In a parallelogram opposite angles are congruent and consecutive angles are supplementary.
∠ S and ∠ V are not opposite angles, they are consecutive, then
∠ S + ∠ V = 180°
50° + ∠ V = 180° ( subtract 50° from both sides )
∠ V = 130°

5 Gretchen borrowed $50 from her parents for 3 months. They charged her 14% interest. How much does she need to pay her parents to pay off the loan?
Step-by-step explanation:
simple interest = principal×rate×time
S.I = $50×(14÷100)×3
S.I=$50×0.14×3
S.I=$21
Amount= principal + simple interest
Amount = $50+$21
Amount = $71

Lab group A got a residual of 14.1005 grams of silver at the end of an experiment. Lab group B got a residual of 11.023 grams of silver at the end of a similar experiment. Using significant digits, find how much more silver lab group A got compared to lab group B.
A. 3.077 g
B. 3.0775 g
C. 3.078 g
D. 3.75 g
Answer:
C. 3.078
Step-by-step explanation:
14.1005 - 11.023 = 3.0775
Then you round the ten thousands place turning 75 into 8 equaling 3.078
Subtraction is a mathematical operation. The amount of silver lab group A got compared to lab group B is 3.0775 gm more.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
The amount of silver that group A got is 14.1005gm, while the amount of silver that group B got is 11.023 grams. Therefore, the amount of silver lab group A got compared to lab group B is,
14.1005 gm - 11.023 gm = 3.0775 gm
Hence, the amount of silver lab group A got compared to lab group B is 3.0775 gm more.
