What is 3+p=8 can i get the answer

1 answer:

7 0

I’m just guessing but I think you subtract the three from itself and from eight . To in the end get five.

Ex:

3+p=8
-3 -3

p=5

Answer:

80°

Step-by-step explanation:

$\angle COB$ is central angle and arc BC is the corresponding arc.

$\therefore \: m (arc \: CB) = m\angle COB \\ \\ \therefore \: m (arc \: CB) =80 \degree$

Katie owns a pretzel stand. Her profit, in dollars, is given by the function , where is the number of pretzels sold. What is the

olga nikolaevna [1]

Using the vertex of the quadratic equation, it is found that the maximum profit she can earn is of $106.

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

$y = ax^2 + bx + c$

The vertex is given by:

$(x_v, y_v)$

In which:

$x_v = -\frac{b}{2a}$

$y_v = -\frac{b^2 - 4ac}{4a}$

Considering the coefficient a, we have that:

If a < 0, the vertex is a maximum point.

If a > 0, the vertex is a minimum point.

In this problem, her profit is modeled by:

$P(x) = -x^2 + 14x + 57$

Which is a quadratic equation with coefficients a = -1, b = 14, c = 57, hence, her maximum profit in dollars is given by:

$y_v = -\frac{14^2 - 4(-1)(57)}{4(-1)} = 106$

Prove that the points P(-1,1) ,Q(2,3) and R(2,1) are the vertices of a salence triangle. Plz ans fast.

guajiro [1.7K]

Step-by-step explanation:

P(-1,1), Q(2,3), R(2,1)

Let P(-1,1)be x1and y1

Q(2,3)be x2 and y2

therefore, by distance formula

d(PQ)= root (x2-x1)^2+(y2-y1)^2

= root[ 2-(-1)] + (3-1)

=root (2+1)^2+2^2

= root (3square +2square )

= root 9+4

d( PQ) = root 13.........(1)

Now find distance QR and PR then prove that the three sides are not equal and therefore it is a scalene triangle

2nd also do the same.
