The discriminant of a quadratic equation is 16. Which number represents the number of real solutions to the equation?

0

3

Answers

Answer 1

Answer:

The

number 2

Step-by-step explanation:

What we need here is just the sign of the discriminant

From the question in this case, the discriminant is positive

Thus, whenever we have a positive discriminant, then the number of real solution is 2 and these two are distinct (different from one another).

Step-by-step explanation:

3 Drag the tiles to the boxes to form correct pairs. Match the expressions with the property used to generate 5y + 2y+ 6+2. Distributive Property 6y - y + 2y + 10 - 4 + 2 5y + 2(y + 3) + 2 combining like terms 5y + 2 + 6 + 2y Commutative Property € cared​

Answers

Answer:

Distributive Property = 5y+2(y+3)+2

combining like terms = 5y+2+6+2y

Commutative Property = 6y-y+2y+10-4+2

Step-by-step explanation:

The correct matching of the properties will be:

Distributive Property = 5y+2(y+3)+2

combining like terms = 5y+2+6+2y

Commutative Property = 6y-y+2y+10-4+2

Original expression: 5y + 2(y + 3) + 2

How to match the value

Apply the distributive property by multiplying 2 to the terms inside the parentheses:

5y + 2y + 6 + 2

Combine like terms:

(5y + 2y) + (6 + 2)

7y + 8

Rearrange the terms using the commutative property:

(7y + 2y) + (6 + 2)

9y + 8 + 8

Simplifying further, we have:

9y + 16

Therefore, the simplified expression is 9y + 16.

f) One number is 78 more than
another. If you add 12 to tbe
smaller number, the result is 50.
What is the larger number?​

Answers

Answer:

The larger number = 116

Step-by-step explanation:

Let the smaller number = x

Given that one number is 78 more than  another, so

The larger number = x+78

Given that if we add 12 to the  smaller number, the result is 50, so

[tex]x+12=50[/tex]

subtract 12 from both sides

[tex]x+12-12=50-12[/tex]

Simplify

[tex]x=38[/tex]

Therefore,

The smaller number = 38The larger number = x+78 = 38+78 = 116

Thus, the larger number = 116

Find the missing angles.

Answers

Answer:

a=30  b=30 c= 75

Step-by-step explanation:

By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.

Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.

So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180

Subtract 30 from both sides and you are left with:

2c = 150

Divide by 2 on each side:

c= 75

Find the zeros of y = x2 – 6x – 4 by completing the square.

Answers

Answer:

The solutions to the quadratic equations are:

[tex]x=\sqrt{13}+3,\:x=-\sqrt{13}+3[/tex]

Step-by-step explanation:

Given the function

[tex]y\:=\:x^2\:-\:6x\:-\:4[/tex]

substitute y = 0 in the equation to determine the zeros

[tex]0\:=\:x^2\:-\:6x\:-\:4[/tex]

Switch sides

[tex]x^2-6x-4=0[/tex]

Add 4 to both sides

[tex]x^2-6x-4+4=0+4[/tex]

Simplify

[tex]x^2-6x=4[/tex]

Rewrite in the form (x+a)² = b

But, in order to rewrite in the form x²+2ax+a²

Solve for 'a'

2ax = -6x

a = -3

so add a² = (-3)² to both sides

[tex]x^2-6x+\left(-3\right)^2=4+\left(-3\right)^2[/tex]

[tex]x^2-6x+\left(-3\right)^2=13[/tex]

Apply perfect square formula:  (a-b)² = a²-2ab+b²

[tex]\left(x-3\right)^2=13[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

solve

[tex]x-3=\sqrt{13}[/tex]

Add 3 to both sides

[tex]x-3+3=\sqrt{13}+3[/tex]

Simplify

[tex]x=\sqrt{13}+3[/tex]

now solving

[tex]x-3=-\sqrt{13}[/tex]

Add 3 to both sides

[tex]x-3+3=-\sqrt{13}+3[/tex]

Simplify

[tex]x=-\sqrt{13}+3[/tex]

Thus, the solutions to the quadratic equations are:

[tex]x=\sqrt{13}+3,\:x=-\sqrt{13}+3[/tex]

If AX:XB as AB:AC, find missing length
AX = 5, CB = 4, AC =6, find AB

Answers

Answer:

AB = 15 ÷ 2

Step-by-step explanation:

The computation of the AB is shown below;

Given that

AX : XB as AB : AC

AX = 5

XB = 4

AC = 6

AB = x

Based on the above information

We can write as

5 : 4 as to x : 6

ratios can be written as fractions

5 ÷ 4 = x ÷ 6

(4)(x) = (5)(6)

4x = 30

x = 30 ÷ 4

x = 15 ÷ 2

Hence, the AB = 15 ÷ 2

If the 8 men on a construction crew make up 40% of the entire crew, how many people are in
the crew?

Answers

Answer:

20

Step-by-step explanation:

Since 40% of the crew are men, which means n.40=8 n=8/.40 n=20 total number of crew 20 - 8=12 are women.

The number of people in the crew is 20.

Let the number of people in the crew be represented by x.

Therefore, 40% of x will be 8. This can then be written as:

40% of x = 8

40/100 × x = 8

0.4 × x = 8

0.4x = 8

Divide both side by 0.4

0.4x/0.4 = 8/0.4

x = 20

Therefore, the number of people in the crew is 20.

A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angular speed of the wheel, in radians per second? Round your answer to the nearest hundredth.

Answers

Answer: 3,140 radians per minute.

Step-by-step explanation:

We know that the wheel does 500 revolutions per minute.

This is called the frequency of the wheel, and this is written as:

f = 500 rev/min = 500 RPM

The angular speed (or Angular velocity) is written as

ω = 2*pi*f

And this quantity is in radians/unit of time.

where pi = 3.14

then:

ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min

This means that the angular velocity  (or angular speed) is 3,140 radians per minute.

To most, he is known simply as Picasso. He was born on October 25th, 1881, and died on April 8, 1973. Pablos father was a drawing teacher, and he encouraged his sons artistic ability. When Pablo was ten years old, the family moved to Barcelona, Spain, where Pablo took an exam to enter a famous and prestigious art school, called La Llonga. The exam was supposed to take one month, but Pablo finished it in one day! He later moved to Paris, where was worked as an artist creating and exhibiting his drawings. During this time, he created his famous Blue Period works. They were called this because of their devotion to the color, and because they were quite somber in nature. In 1907, Picasso painted Les Demoiselles dAvignon, which is known to have been the first painting in the modern art movement. Artists from all over the world travelled to see this painting. Picasso created cubism, with a colleague named George Braque In the 1920s, Picasso continued his work by creating theatre sets. His work during this period was considered neo-classical, modern, surreal, and cubist. In 1937, there was a terrible bombing in a small Spanish town called Guernica. Picasso reacted by creating one of his most famous murals, a masterpiece named after the town of Guernica. Picasso then moved on to print making and lithography. He was never content to use a medium the way it was traditionally used, and came up with many inventive new ways to create art. He worked on etchings, engravings, and worked on many other techniques. Just before his 87th birthday, he completed a series called the 347 Series, in which he created three hundred and forty seven pieces of etching and engraving work between March and October! One of the most interesting things about Picasso is that he was the first artist to be famous during his own lifetime. He was quite a celebrity, and is considered one of the most important artists of the twentieth century.
