In which quadrant(s) do the graphs of y=x^2 and y=3x+10 intersect?

Answers

Answer:

Quadrants I and II

Step-by-step explanation:

y = x²

y = 3x + 10

x² = 3x + 10                     Substitute x² for y

x² - 3x - 10 = 0                 set the equation = 0

(x - 5) (x + 2)                     Factoring

x - 5 = 0 ; x + 2 = 0

x = 5 or x = -2

Now solving the y

y = x²     or     y = x²

y = (5)²   or y = (-2)²  

y = 25   or  y = 4

The points of interception is points (5, 25) or (-2, 4)  

(5, 25)  in Quadrant I ; (-2, 4) in Quadrant II

Answers

Answer:

1024

Step-by-step explanation:

The expression can be written as [tex]8 * 2^7[/tex]

What is power?

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

Example: The standard form of the polynomial 5 + 2x + x² is expressed.

We shall first determine the polynomial's degree before expressing it in standard form.

The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.

Given:

8*2^7

The above expression can be written as

[tex]=8 * 2^7[/tex]

= 8 x 128

= 1024.

Hence, the expression can be written as [tex]8 * 2^7[/tex]

Answer:

  c = 108°

  d = 106°

Step-by-step explanation:

There are 2 basic rules involved here. From them, a number of others can be derived in order to simplify some calculations.

angles forming a linear pair are supplementary (total 180°)interior angles of a triangle total 180°

The derived relations we can use in this problem are ...

vertical angles are congruentan exterior angle of a triangle is equal to the sum of the opposite interior angles

__

c

The vertical angle to 78° is one of two remote interior angles with respect to exterior angle c. The other is the one marked 30°. That means ...

  c = 78° +30* = 108°

__

d

Angles d and 30° are two of the three angles in the largest triangle. The third is the vertical angle to 44°, so it is 44°. The sum of angles in that triangle is 180°:

  d + 30° +44° = 180°

  d = 180° -74° = 106°

list the side of the triangle in order from shortest to longest.

Answers

Answer:

shortest to longest -

B-77

A-59

C-44

Step-by-step explanation:

To put the sides in order of longest to shortest, first find the largest angle -- the longest side is opposite this angle. Then, find the second largest angle and the side opposite from it to find the next largest angle, and finally, the shortest side will be opposite the smallest angle.

Answers

Answer:

2nd option

Step-by-step explanation:

given a quadratic in standard form

y = ax² + bx + c

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here a = - 1 < 0 then maximum

The maximum value is the value of the y- coordinate of the vertex

The x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

Here a = - 1 and b = 3 , then

x = - [tex]\frac{3}{-2}[/tex] = [tex]\frac{3}{2}[/tex]

Substitute this value into the equation for corresponding y- value

y = - ([tex]\frac{3}{2}[/tex] )² + 3([tex]\frac{3}{2}[/tex] ) - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{9}{2}[/tex] - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{18}{4}[/tex] - [tex]\frac{4}{4}[/tex] = [tex]\frac{5}{4}[/tex]

Sara’s mother is now four times as old as Sara. In five years, she will be three times as old as Sara. What are their ages now?​

Answers

Answer:

Sara's mother age : 40 years

Sara's age : 10 years

Step-by-step explanation:

Let Sara's mother age be x

and Sara age be y

Given , Sara's mother is now four time as old as Sara

• x = 4y ...1

also, in five years , she will be three times as old as Sara

In five years , Sara's mother age :- ( x + 5 )

Sara age :- ( y + 5 )

according to the question,

x + 5 = 3 ( y + 5 )

x + 5 = 3y + 15

x - 3y = 10 ... 2

putting value of x from 1 into 2

4y - 3y = 10

y = 10

putting y value in 1

x = 4y = 4 ( 10 ) = 40

So, Sara's mother age is 40years

and Sara's age is 10years .

Lucy spent $3.19 on a sparkly headband and $2.67 on a shiny bracelet. How much more did Lucy spend on the sparkly headband?

Answers

Answer:

$0.52

Step-by-step explanation:

3.19 (headband) - 2.67 (bracelet) = 0.52

Lucy spent 52 cents more on the sparkly headband than the shiny bracelet.

To find the answer, you would subtract the amount of the sparkly headband with the amount of the shiny bracelet, which would leave you with a sum of 0.52 cents.

3.19-$2.67=0.52

Answer:

n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.

Step-by-step explanation:

Answer:

Natural numbers are simply positive integers.  For now, refer to the middle number (the third number), as x.  Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2.  Simply add all these numbers to get 5x, a number that is divisible by 5.  As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.

#5) Its line “k”

Well to solve this you need to know what negative slopes are.

They decrease from height from left to right

And also a slope is always calculated like this

rise -> run

Think of it like a bed.

You have to wake up which means you have to rise and then you run to do whatever it is you gotta do.

Rise is going vertical and run is going horizontal.

So for line K you have it because since its negative its -3/1 so technically its -3 rise(basically fall since its negative), 1 run (right).

#6) 1/2  is the slope of line N. Or (c)

Well n is a potsive slope so we can automatically remove a and b.

And we can count like this, it started from the orgin it looks like (but you can use any given point really) and then just follow it, rise 1 and run 2. Rise 2 and run 3 doesn’t work so it has to be 1.2 or (c)
