f(x)=x^2+12x+34
Answer:
(-6, -2)
Step-by-step explanation:
[tex]f(x) = {x}^{2} + 12x + 34[/tex]
[tex] = f(x) = {1x}^{2} + 12x + 34[/tex]
= a = 1, b = 12
[tex] = x = - \frac{12}{2 \times 1} [/tex]
[tex] = x = - \frac{12}{2} [/tex]
= x = -6
[tex] = f(x) = {x}^{2} + 12x + 34.. = - 6[/tex]
[tex] = f( - 6) = - 2[/tex]
= (-6, -2)

Trista has 8 mg of iron and 0.83 mg of tin.
How much more iron does she have than tin?
8.83 mg
7.17 mg
7.27 mg
71.7 mg
Here, we need to subtract the quantity of tin from the quantity of iron in order to find how much more iron Trista has than tin
The quantity of iron Trista has more than tin is 7.17 mg
Quantity of iron = 8 mg
Quantity of tin = 0.83 mg
Quantity of iron Trista has more than tin = Quantity of iron - Quantity of tin
= 8 mg - 0.83 mg
= 7.17 mg

Karima earns $400 per week plus a holiday bonus of $250. Write an expression to represent the total amount she earns after working w weeks. Then, find the amount she earns after she works 4, 12, and 36 weeks.
Expression:
Earnings at 4 weeks:
Earnings at 12 weeks:
Earnings at 36 weeks:
Answer:
Step-by-step explanation:
Earnings per week = $ 400
Earning for 'w' week = 400*w + holiday bonus
= 400w + 250
Earnings at 4 weeks = 400*4 + 250
= 1600 + 250
= $ 1850
Earnings at 12 weeks = 400*12 + 250
= 4800 + 250
= $ 5050
Earnings at 36 weeks = 400*36 + 250
= 14400 + 250
= $ 14650

Which expression is equivalent to 180?
Answer:
[tex] \sqrt{2.2.3.3.5} [/tex]
[tex]\sqrt{2.2.3.3.5}[/tex] is equivalent to [tex]\sqrt{180}[/tex]. Correct option is 1. First, we look for perfect square factors within 180. We can factor 180 as follows: [tex]\(180 = 2^2 \times 3^2 \times 5\)[/tex]
Next, we can group the perfect square factors together:
[tex]\(180 = (2 \times 3)^2 \times 5\)[/tex]
Since we are taking the square root of 180, we can rewrite it as the square root of its perfect square factors multiplied by the remaining non-perfect square factor:[tex]\(\sqrt{180} = \sqrt{(2 \times 3)^2 \times 5}\)[/tex]
The square root of a perfect square is just the value of the number itself:
[tex]\(\sqrt{180} = 2 \times 3 \times \sqrt{5}\)[/tex]
Finally, we can simplify the expression by multiplying the numbers outside the square root [tex]\(\sqrt{180} = 6\sqrt{5}\)[/tex]
So, the expression [tex]\(6\sqrt{5}\)[/tex] is equivalent to [tex]\(\sqrt{180}\)[/tex], and it represents the positive square root of 180 with any perfect square factors taken outside the square root sign.

Find the image of (-1, 3) obtained by translating
2 units down, followed by a rotation of 180°
counterclockwise about the origin.
HELP QUICK
Answer:
(1, - 1 )
Step-by-step explanation:
A translation of 2 down means subtract 2 from the y- coordinate
(- 1, 3 ) → (- 1, 3 - 2 ) → (- 1, 1 )
Under a counterclockwise rotation about the origin of 180°
a point (x, y ) → (- x, - y ) , then
(- 1, 1 ) → (1, - 1 )
Overall
(- 1, 3 ) → (- 1, 1 ) → (1, - 1 )
The image of (-1, 3) was obtained by translating 2 units down, followed by a rotation of 180° counterclockwise about the origin is (1,-1).
What is coordinate?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The given point with coordinates of (-1,3), when translated downwards will have the coordinated equal,
(-1,3) ⇒ (-1, 3-2) ⇒ (-1, 1)
Now, since the translation is about 180° in the counter-clockwise direction, the coordinates of the new point will be equal to,
(-1,1) ⇒ (1, -1)
Hence, the image of (-1, 3) obtained by translating 2 units down, followed by a rotation of 180° counterclockwise about the origin is (1,-1).

Point N is on line segment \overline{MO}

. Given MN=2x,MN=2x, NO=x-2,NO=x−2, and MO=2x+9,MO=2x+9, determine the numerical length of \overline{MN}.
MN
.
Answer:
NO = 10
Step-by-step explanation:
The segment addition theorem tells you ...
MN + NO = MO
Substituting the given expressions for these lengths, we have ...
x + 5x = 3x+6
3x = 6 . . . . . . . . . subtract 3x
x = 2 . . . . . . . . . . divide by 3
We can use this value to find the length NO:

Which equation represents a population of 370 animals that increases at an annual rate of 11% ?
Answer:
D.
Step-by-step explanation:
the starting number is 370 and it gets multiplied by 1.11 every year so you would root the equation by t
The equation fourth represents the population of 370 animals that increases at an annual rate of 11% option fourth is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x
where a is a constant and a>1
We have:
A population of 370 animals that increases at an annual rate of 11%
Initial value a = 370
rate r = 11% = 0.11
The equation:
[tex]\rm p = a(1 + r)^t[/tex]
[tex]\rm p = 370(1 + 0.11)^t[/tex]
Thus, the equation fourth represents the population of 370 animals that increases at an annual rate of 11% option fourth is correct.

an angle measures 15 degrees more than its complement. Find the measures of the two angles
Answer:
The first angle is 37.5° and the second would be 52.5°
Step-by-step explanation:
Angles are complementary when their sums add up to 90°.
[tex]x+(x+15) = 90\\x+x+15=90\\x+x=75\\x=37.5[/tex]
The first angle is 37.5° and the second would be 52.5°, after we plug in x.
Have a nice day. Feel free to ask questions. Spread The Love.
Answer:
Angle 1 = x = 37.5°Angle 2 = x + 15 = 52.5°Concept:
Here, we need to know the idea of the complementary angle.
Two angles are said to be complementary if they add up to 90 degrees.
Be aware that three or more angles cannot be complementary even if their sum is 90 degrees.
Solve:
Given information
Angle 1 = x
Angle 2 = x + 15
Given expression deducted from the definition of the complementary angle
Angle 1 + Angle 2 = 90
Substitute values into the expression
(x) + (x + 15) = 90
Combine like terms
(x + x) + 15 = 90
2x + 15 = 90
Subtract 15 on both sides
2x + 15 - 15 = 90 - 15
2x = 75
Divide 2 on both sides
2x / x = 75 / 2
[tex]\boxed{x=37.5}[/tex]
Find the measure of angle 2
Angle 2 = x + 15 ⇔ Given expression
Angle 2 = (37.5) + 15 ⇔ Substitute values into the expression
Angle 2 = [tex]\boxed{52.5}[/tex] ⇔ Simplify by addition
