Quiz 1 4/25= 16%
Quiz 2 31/33= 93.3%
Percentage difference 93.3%-16%= 77.9%

First test: 21 out 25 = 84%
Second test: 31 out of 33 = 93%
So the percent difference would be 9%.

If the domain of the square root function f(x) is x<7, which statement must be true?
Delicious77 [7]

Answer:

The x-term inside the radical has a negative coefficient

Step-by-step explanation:

The argument of a square root should be ALWAYS greater or equal to zero. If the domain of the function is x<7, rearranging, we have: 0<x-7

Therefore the argument is: x-7, and the function is: y = √(x-7)

The statement "The x-term inside the radical has a negative coefficient" is the right answer.

The gradient of the given graph is 1.5

<h3>Calculating Gradient </h3>

From the question, we are to determine the gradient of the graph

Gradient is given by the formula

m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }

Where m is the gradient

Picking the points (-2, -2) and (2, 4) on the line

Then,

x₁ = -2

y₁ = -2

x₂ = 2

y₂ = 4

Putting the parameters into the equation, we get

m = \frac{4--2}{2--2}

m = \frac{4+2}{2+2}

m = \frac{6}{4}

m = 1.5

Hence, the gradient of the given graph is 1.5

Eya is 5 years younger than 3 times Bills age. If Eya is 28 how old is Bill?
Sedaia [141]
Bill's age = x

Eya's age = 3x - 5

Eya is 28

28 = 3x - 5

28 (+5) = 3x -5 (+5)

33 = 3x

33/3 = 3x/3

x = 11

Bill = x

x = 11

Bill is 11 years old

hope this helps

F(x)=tan(x)
AleksAgata [21]
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>
