Answer:

91.7 inches to 1 decimal place

Step-by-step explanation:

We will use Pythagoras's theorem to find the height of the pyramid.

The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.

We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in

slant height = 92.3in

Therefore height = $\sqrt{92.3^{2} -10.2^2} =91.73in$

The height of the pyramid is 91.73inches to 1 decimal place

Which is an x-intercept of the continuous function in the table?

Ad libitum [116K]

Answer:

B. (3, 0)

Step-by-step explanation:

The x-intercept is the point where the graph of the function meets the x-axis.

At x-intercept, y=0 or f(x)=0

So look through the table and find where f(x)=0.

From the table, f(x)=0 at x=3.

We write this as an ordered pair.

Therefore the x-intercept is (3,0)

The correct choice is B.

Rachel is using grouping to find the factors of a quadratic expression. She has reached the step shown below. Determine the fact

Feliz [49]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

If the factored form is given by

$(3x-4)(x+2)$

Then its standard form will be given by

$(3x-4)(x+2)\\\\=3x^2+6x-4x+8\\\\=3x^2+2x+8$

if factored form is given by

$(3x+2)(x+4)$

Then its standard form will be given by

$(3x+2)(x+4)\\\\=3x^2+12x+2x+8\\\\=3x^2+14x+8$

Hence, only first option is correct.

Evaluate: log1255 - | - | N | DONE o o o

Bas_tet [7]

Answer:

$\log_5(125) =3$

Step-by-step explanation:

Question:

To evaluate $\log 125$ to the base 5

Solution:

We will apply log properties to evaluate.

We will use the following property of logarithms

If $\log _ab=x$

Then, $a^x=b$

Let $\log_5(125) =x$

So, we have

$5^x=125$

We can write $125=5\times 5\times 5=5^3$

$5^x=5^3$

∴ $x=3$

Thus, we have

$\log_5(125) =3$
