Answer:

C. 24 ft.

Step-by-step explanation:

There is a right triangle which can be drawn in side the pyramid with height h, hypotenuse 25 ft and bas = 1/2 * 14 = 7.

So using Pythagoras:

25^2 = h^2 + 7^2

h^2 = 25^2 - 7^2

h^2 = 576

h = √576 = 24 ft.

Which of the following point-slope form equations could be produced with the points (4, 5) and (-3, -5)?

NikAS [45]

Answer:

Equation; y = 1 3 / 7x - 5 / 7

Step-by-step explanation:

First consider the slope of this equation we must derive;

Slope Formula = Rise / Run,

y2 - y1 / x2 - x1 ⇒

5 - ( - 5 ) / 4 - ( - 3 ) ⇒

10 / 7 ⇒ Slope : 1 3 / 7

So far we can formulate an equation as such;

y = 1 3 / 7 * x + b, where b ⇒ y - intercept

Given one of the points, substitute into this equation solving for b;

5 = 1 3 / 7 * ( 4 ) + b,

5 = 40 / 7 + b,

b = - 5 / 7

From this we can derive one point - slope from equation to be :

Equation; y = 1 3 / 7x - 5 / 7

1.Use Euler’s Formula to find the missing number. Edges: 40

PtichkaEL [24]

Answer:

Euler's Formula states that:

V -E +F = 2 meaning that the vertices minus the edges plus the faces of a convex polyhedron will always equal two.

So, for the initial question, we have 40 edges and 24 faces.

So, vertices = 2 + Edges -Faces

Vertices = 2 + 40 - 24

Vertices = 18

Use set-builder notation to describe the following sets: (a) {1,2,3,4,5,6,7} (b) {1, 10, 100, 1000, 10000} (c) {1,1/2, 1/3, 1/4,

Alja [10]

Answer:

A) The set builder notation is: {n | n∈Z, 1≤n≤7}.

B) The set builder notation is: $\{10^x | x=0,1,2,3,4\}$

C) The set builder notation is: $\{\frac{1}{n} | n\in z\}$

D) The set builder notation can be: $\{x\ \in R | x=x^3\ and\ x\neq 1\}$

Step-by-step explanation:

Consider the provided information,

We need to use set-builder notation to describe the following sets.

(a) {1,2,3,4,5,6,7}

Here, the number are integer starting from 1 to 7.

Thus, the set builder notation is: {n | n∈Z, 1≤n≤7}.

(b) {1, 10, 100, 1000, 10000}

The above set can be written as:

$\{1, 10, 100, 1000, 10000\}=\{10^0, 10^1, 10^2, 10^3, 10^4\}$

Thus, the set builder notation is: $\{10^x | x=0,1,2,3,4\}$

(c) {1, 1/2, 1/3, 1/4, 1/5, ...}

Here the numerator is 1 for each term but denominator is natural number.

Thus, the set builder notation is: $\{\frac{1}{n} | n\in z\}$

(d) {0}

The set builder notation can be: $\{x\ \in R | x=x^3\ and\ x\neq 1\}$
