The output value of f(5) in the given function f(x) = -4x - 5 is -25

A function is simply a set of ordered pairs where each first element is paired with one and only second element and also no element in either pair is without a partner.

Given the data in the question;

To determine the output value of f(5), replace the variable x with 5 and simplify.

f(x) = -4x - 5

f(5) = -4(5) - 5

Perform the multiplication operation to remove the parenthesis.

f(5) = -4(5) - 5

f(5) = -20 - 5

f(5) = -25

Therefore, the output value of f(5) in the given function f(x) = -4x - 5 is -25.

Answer:

Answer: 57 & 59

Step-by-step explanation:

Let us assume first odd integer is 'x'

Then, next consecutive integer should be 'x+2'. RIGHT?

Now, put in the form of equation:

x + (x+2) = 116

x + x + 2 = 116

2x + 2 = 116

2x = 116 - 2

2x = 114

x = 114 / 2 => 57

Now, put the value of 'x' in second step:

           x + 2 => 57 + 2 = 59

Therefore, answer would be 57 & 59

The measure of ∠B round to the nearest whole number is 76°.

Cosine is the trigonometric function that is equal to the ratio of the side adjacent to the acute angle in a right angled triangle.

Mathematically,

           Cos = Base/Hypotenuse

Now given that, a triangle ABC,

AB = 21

BC = 7

∠C = 90°

Thus, we have

hypotenuse = AB

Base = BC

Perpendicular = AC

So, for angle B

CosB = Base/Hypotenuse

⇒ CosB = BC/AB

Put the values we get,

⇒ CosB = 7/21

or,

CosB = Cos(75.53°)

⇒ B = 75.53°

Now the nearest whole number to 75.53° is 76°

Thus, we get

B = 76°

Thus, the measure of ∠B round to the nearest whole number is 76°.

Step-by-step explanation:

The negation is "antarctica is not in the northern hemisphere" &  the truth value of the original proposition is FALSE and its negation is TRUE.

The sentences that can be classified as true or false , but not both are called as propositions.

For Example , "Shirt is yellow" is a proposition whereas "a is less than 2" is not a proposition as the value of a is not fixed.

Negation of proposition means writing the opposite of the given proposition.

If the proposition is true then it's truth value is "True".

If the proposition is false then it's truth value is "False".

According to the given Question

The negation of the statement "antarctica is in the northern hemisphere" is "antarctica is not in the northern hemisphere"

The truth value of the original proposition is FALSE as Antarctica is in the Southern hemisphere.

The truth value of the negation is TRUE as Antarctica is not in the Northern hemisphere it is in southern Hemisphere.

first you take out the exponent (2) by getting the square root of 18 so the equation will be 4x+3=18squared rooted. the primary factors of 18 are 2*3 squared. so instead of 18 put the factors is.so now you will get

4x+3=3^2*2 square rooted.

then you apply the radical rule so square root each of the digits.that will simplify to 4x=3square rooted by 2 divide by 4 on both sides minus 3/4 and if you simplify it should give you the answer

Answer:

a = 10

Step-by-step explanation:

The image is showing a linear pair which equals 180°
104° is shown.

If you take 180° and subtract 104° you should get the answer to what (8a -4)° should equal to.

180° - 104° = 76°

Your equation should look like : 8a - 4 = 76°
-- Add 4 to both sides

8a - 4 = 76°
     +4    +4

= 8a = 80
-- Divide 8 on both sides

8a/8 = 80/8

a = 10

Proof:

8(10) - 4 =
80 - 4 = 76°

104° + 76° = 180°

Answer:

[tex]f(x)=-x^2 + 11x - 24[/tex]

Step-by-step explanation:

Well for this problem, you want to start off by writing it in factored form.

In factored form, you can represent a quadratic as: [tex]f(x)=a(x-b)(x-c)[/tex], where x=b, and x=c are zeroes of the function, since plugging them into the function makes one of the factors zero, and multiplying zero by the other factors will just give you zero.

The "a" in front of the two factors generally defines the stretch/compression of the function.

So let's start by plugging in the zeroes into the function, and then we can solve for "a" later: [tex]f(x) = a(x-3)(x-8)[/tex]

Now let's use one point on the graph, which is not a root/zero to solve for "a". It's important to not use a zero/root since if we use that point the entire thing will be zero regardless of the value of "a"

Luckily we have one point provided that is not a zero and is: (4, 4)

So let's plug it in: [tex]4=a(4-3)(4-8)\\4=a(1)(-4)\\4=-4a\\a=-1[/tex]

So now let's plug this into the factored form to get: [tex]f(x)=-(x-3)(x-8)[/tex]

using foil to multiply these two factors you get: -[x^2 -8x - 3x + 24]

Now combine like terms

-[x^2 - 11x + 24]

distribute the negative sign

-x^2 + 11x - 24

[tex] \large \bf \implies{y = { - x}^{2} + 11x - 24}[/tex]

The solution of the given equation by rounding off it to the nearest ten-thousandth is 10.0427.

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation:  log 4 + 2 log x = 6

We are given a logarithmic expression: log 4 + 2 log x = 6  

We know that e^(log b) = b

a log b = (log b)^a

log a + log b = log (ab)

Using exponential on both sides, we have

e^(log 4 + 2 log x) = e^6

e^(log 4 + log x² ) = 403.428

e^(log 4x² ) = 403.428

4x² = 403.428

x² = 403.428 / 4

x² = 100.857

x = 10.0427

Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 10.0427.

In this problem we find four points set on Cartesian plane, each of which has to be transformed by using the following transformation rule about the origin:

(x', y') = (x · cos θ - y · sin θ, x · sin θ + y · cos θ)

Where:

(x, y) - Coordinates of the original point.

θ - Angle of rotation, in degrees.

If we know that B(x, y) = (- 2, 0), C(x, y) = (- 4, 3), Z(x, y) = (- 3, 4), X(x, y) = (- 1, 4) and θ = 90°, then the coordinates of the resulting point:

B'(x, y) = (- 2 · cos (- 90)° - 0 · sin (- 90°), - 2 · sin (- 90°) + 0 · cos (- 90°))

B'(x, y) = (0, 2)

C'(x, y) = (- 4 · cos (- 90°) - 3 · sin (- 90°), - 4 · sin (- 90°) + 3 · cos (- 90°))
