If f(x) = 2x2 + 4 and g(x) = x - 6, determine f(-5) - g(-5).
53
-49
55
65
which one is the answer
Answer:
65
Step-by-step explanation:
f(x) = 2x² + 4
g(x) = x - 6
f(-5) = 2 * (-5)² + 4
= 50 + 4
= 54
g(-5) = - 5 - 6
= - 11
f(-5) - g(-5) = 54 + 11 = 65

Answer:
step 2 is the answer. when you start the question it's already in pemdas order. 48÷6 equals 8 then multiply it by the other 8 then you can add that quotient to the 10 which is 74 then subtract it by 7 and you get 67. step 2 goes the wrong way and ads the 8 with the 10 before multiplying the 8 by the 8 making everything go in wrong turns.
Any languages have what some consider a significant limitation: they lack a gender-neutral third-person singular pronoun. When using a pronoun to refer to a person, speakers must either specify a gender or say something like "he or she." Not only can this be cumbersome, but it means that there is no good pronoun choice when a person's gender is unknown to the speaker. Sweden addressed this problem in 2015 by adding a new pronoun—hen—which refers to a person without specifying a male or female gender. Hen does not replace the Swedish pronouns han, meaning "he," or hon, meaning "she"; it simply adds another option. Thus, Swedes now have their choice of three,

Choose the graph of the solution to this inequality. c – 12 ≥ –16 A number line with a closed dot at negative 4 shaded to the right. A number line with a closed dot at 4 shaded to the left. A number line with a closed dot at 4 shaded to the right. A number line with a closed dot at negative 2 shaded to the right.
A number line with a closed dot at -4 is shaded to the right. Option A is correct.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
Given inequality,
c – 12 ≥ –16
Add 12 on both sides
c ≥ -4
So the required number line would be as a closed dot at -4 and shaded to the right.
Thus, A number line with a closed dot at -4 is shaded to the right. Option A is correct.

The height (one of the legs) and the hypotenuse of an isosceles right triangle are 40 feet and 40√2 feet, respectively.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
The triangle is an isosceles right triangle.
That means, the triangle has two equal sides.
Let, base b = height h.
The area of the triangle = 1/2 x base x height.
800 = (1/2)b²
b² = 1600
b = 40 feet.
Now, using the Pythagoras theorem,
Hypotenuse = √(1600 + 1600)
Hypotenuse = √(3200)
Hypotenuse = 40√2 feet.
Therefore, height = 40 feet and hypotenuse = 40√2 feet.

What is an exponential graph?A curve that depicts an exponential function is known as an exponential graph. A curve with a horizontal asymptote and either an increasing slope or a decreasing slope called an exponential graph. i.e., it begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates.
Given the graph of function,
The graph of any exponential function is parallel to an axis and drop and increase show the decay or growth,
since the equation,
y = -2(3ˣ) + 5
has a negative sign the graph will go down,
y-intercept for the graph is 3,
when x = 0, y = 3
and the graph will be in the fourth quadrant.
Hence the graph will be in the fourth quadrant.

What is trigonometric ratio?In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent.
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
Given in the figure,
ABC is right angle triangle
∠BAD = 90°
∠ABD = ?
AB = 125 ft
AD = 140 ft
tan ∠ABD = AB/AD

The circumference of a circle is 106.76 meters. What is the circle's diameter?
Answer:
33.98
Step-by-step explanation:
To find the diameter of a circle when you have a circumference, all you need to do is divide the circumference by pi. (So 106.76 ÷ π)
So:
106.76 ÷ π = 33.98276344.... (irrational number)
I just cut off the rest of the numbers at the hundredth place for simplicity. Another way you could put it is:

Remark
The general equation for a line is y = mx + b
You know that m = 1/4. The problem is what do you do about (2,0)?
Solution
y = 1/4 x + b Let x = 2 when y = 0
0 = 1/4 * 2 + b multiply 2 * 1/4
0 = 1/2 + b Subtract 1/2 from both sides
b = - 1/2
