Mathematics
1 answer:
Serjik [45]3 years ago
4 0

Answer:

Complex Roots. The Fundamental Theorem of Algebra states that every polynomial of degree one or greater has at least one root in the complex number system (keep in mind that a complex number can be real if the imaginary part of the complex root is zero).

Step-by-step explanation:

What is the distance around a triangle that has sides measuring 21/8 feet, 31/2 feet and 21/2 feet?
sleet_krkn [62]
Add all of the sides together. Make sure to use a common denominator because you are adding fractions. Don't forget your unit label (feet)
\frac{21}{8} + \frac{31}{2} + \frac{21}{2}
\frac{21}{8} + \frac{124}{8} + \frac{84}{8}
\frac{229}{8} feet

The table shows the proof of the relationship between the slopes of two perpendicular lines. What is the missing statement in st
Assoli18 [71]

Answer:

\frac{AB}{BC} = \frac{CE}{ED}

Step-by-step explanation:

Given

The attached proof

Required

Complete the missing piece

In (a), we have:

\triangle ABC \to \triangle CED

This implies that, the following sides are similar:

AB \to CE

AC \to CD

BC \to ED

An equation that compares the triangle can be any of:

\frac{AB}{BC} = \frac{CE}{ED}

\frac{AB}{AC} = \frac{CE}{CD}

.....

From the options;

\frac{AB}{BC} = \frac{CE}{ED} is true

Can someone help me with these
Stolb23 [73]

Answer:

Problem 2) : the gradient is "-2", and the y-intercept is "3"

Problem 3)

A is  y=2x+2

B is y=x+2  

Step-by-step explanation:

Problem 2)

In the line given by the equation:   y=-2x+3

the "gradient" (also known as "slope") is the numerical coefficient that multiplies the variable "x". So in this case the gradient is "-2"

the y-intercept is the numerical term "+3" because that is the y-value result of evaluating the expression for x = 0

y=-2x+3\\y=-2\,(0)+3\\y=3

Problem 3)

Consider the two lines :

y=x+2  and  y=2x+2

notice that both have the same y-intercept (that is the numerical term "2" at the end of both expressions. That means that both lines cross the y-axis at the point y=2.

Now notice that the gradient of one of them is "1"  (for y=x+2 ) that is the coefficient that multiplies the variable "x". While for the other line ( y=2x+2)  the gradient is "2" and therefore steeper than the previous one.

Then, the line identified as "A" which is the one with steeper gradient, corresponds to the equation   y=2x+2, and the line identified with "B" is the one with smaller gradient  y=x+2  .
