What is the answer to -5+2/3 hurry please

Note: this is assuming you haven't reached complex numbers yet

=============================================================

Explanation:

The given equation 13u^2+23u = -112 is the same as 13x^2+23x = -112

and we can add 112 to both sides getting 13x^2+23x+112 = 0

We see the equation is in the form ax^2+bx+c = 0

The discriminant is

D = b^2 - 4ac

D = 23^2 - 4(13)(112)

D = -5295

The negative discriminant means there are no real number solutions.

-----------

Extra info:

If D = 0, then there would be exactly one real number solution.

If D > 0, then there would be two distinct real number solutions.

Answer:

it is complex solution

no real number solution

Step-by-step explanation:

13u²+23u=-112

13u²+23u+112=0  

a=13, b=23 , c=+112

u= (-b±√(b²-4ac))/2a

u=[(-23±√(23)²-4(13)(112)]/2(13)

u=(-23±√-5295)/26

u=(-23±i√5295)/26

Answer:

[tex] Quotient = \frac{8 - 2t}{3} [/tex]

Step-by-step explanation:

Quotient, in maths, is what you get when two number or expressions together. That is, dividend over the divisor.

Thus, from what we're given:

dividend is 8 decreased by 2 times t, which can be expressed as [tex] 8 - 2*t = 8 - 2t [/tex].

The divisor is 3.

[tex] Quotient = \frac{8 - 2t}{3} [/tex]

Answer:

CD = √11 and CE = √11

Step-by-step explanation:

We know that m∠D is 45° (by using the sum of interior angles in a triangle) so therefore, ΔDCE is a 45 - 45 - 90 triangle (the 45, 45, and 90 refer to the angle measures). The ratio of sides in a 45 - 45 - 90 triangle is 1 : 1 : √2 where the 1s are the sides and the √2 is the hypotenuse. We need to solve for x in x : x : √22. If you notice that √22 = √2 * √11, we can use this to find x, therefore, x = 1 * √11 = √11 so CD = √11 and CE = √11.

Answer:

[tex]\huge \boxed{CD =\sqrt{11} } \\ \\ \huge \boxed{CE =\sqrt{11} }[/tex]

Step-by-step explanation:

The triangle is a right triangle.

We can apply trigonometric functions to solve for the missing sides.

sin θ  = opp/hyp

sin 45 = CD /√22

Multiply both sides by √22.

√22 sin 45 = CD

√11 = CD

cos θ = adj/hyp

cos 45 = CE /√22

Multiply both sides by √22.

√22 cos 45 = CE

√11 = CE

There's "8. '' In the first, is this also included? Or it's the number of the expression?

Answer:

Step-by-step explanation:

Darren has 84 DIMES and 144 PENNIES:

the ratio of dimes to penny=84/144=7/12

12 is GCF : 84/12=7, 144/12=12

Eugene has 63 DIMES and 112 PENNIES :

the ratio is 63/112=9/16

GCF of (63 and 112) is 7 : 63/7=9 , 112/7=16

7/12 = 0.58333            9/16=0.5625

7/12 is higher than 9/16

Darren has the higher ratio of DIMES TO PENNIES in his piggy bank

this can be solved by finding the percentage 7/12=0.5833=58.3% and 9/16=0.5625 which is 56.25%

[tex]-\frac{2}{21}[/tex]

Step-by-step explanation:

Step 1: Have a common denominator

[tex]\frac{12}{21}a -\frac{14}{21}a\\[/tex]

Step 2: Subtract to get answer

[tex]\frac{12}{21}a -\frac{14}{21}a = \frac{-2}{21}a[/tex]

Therefore the answer is [tex]\frac{-2}{21}a[/tex]

Answer:

-2/21a

Step-by-step explanation:

The common number  for this two denominator, 7 and 3, is 21.

21/7=3, so you multiply 3 with the numerator 4. giving 12/21a.

You do the same you -2/3a, and you end up getting the equation of:

12/21a-14/21a=-2/21a.

Answer:

3

Step-by-step explanation:

Hello!

It is asking for the answer is p is equal to 3 so we put 3 in for p

3 = 2n - 3

Add 3 to both sides

6 = 2n

Divide both sides by 2

3 = n

The answer is 3

Hope this helps!

Answer:

n = 3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

*3-(2*n-3)=0

Pull out like factors:

*6 - 2n  =   -2 • (n - 3)

Solve:

*-2   =  0 (This has no equation so we solve for the next side.)

*n-3 = 0 (Add 3 to both sides)

Answer:

3/5

Step-by-step explanation:

A conic section with a focus at the origin, a directrix of x = ±p where p is a positive real number and positive eccentricity (e) has a polar equation:

[tex]r=\frac{ep}{1 \pm e*cos(\theta)}[/tex]

Given the conic equation   [tex]r=\frac{3}{5-3cos(\theta)}[/tex]

We have to make the conic equation to be in the form [tex]r=\frac{ep}{1 \pm e*cos(\theta)}[/tex].

[tex]r=\frac{3}{5-3cos(\theta)}\\\\Multiply\ the\ numerator\ and \ denominator\ by \ 1/5\\r=\frac{3*\frac{1}{5} }{(5-3cos(\theta))*\frac{1}{5}}\\\\r=\frac{3*\frac{1}{5} }{5*\frac{1}{5}-3cos(\theta)*\frac{1}{5}}\\\\r=\frac{\frac{3}{5} }{1-\frac{3}{5}cos(\theta)}[/tex]

Comparing with  [tex]r=\frac{ep}{1 \pm e*cos(\theta)}[/tex]. gives:

e = 3/5, p = 1

The eccentricity is 3/5

Greetings from Brasil...

Here, just apply the Metric Relationships to the Rectangle Triangle

AB² = BC · BD

10² = 16 · X

16X = 100

X = 100/16

        simplify

          100 ÷ 4 = 25

          16 ÷ 4 = 4

X = 25/4

In triangles ABD and CAD, The value of x in the figure is,

⇒ x = 25 / 4

Triangle is a three sided polygon, that has three vertices and three angles which has the sum 180 degrees, is called a triangle.

We have to given that;

Two triangles ABD and CAD are similar.

⇒ Δ ABD ≈ Δ CAD

Hence, We can Just apply the Metric Relationships to the Rectangle Triangle as;

⇒ AB² = BC · BD

Substitute all the values , we get;

⇒ 10² = 16 × x

⇒ 16x = 100

Divide by 16 both side, we get;

⇒ x = 100/16

⇒ x = 25/4

Therefore, In triangles ABD and CAD,

We get;

The value of x in the figure is,

⇒ x = 25 / 4

Answer:

The correct option is;

B. The difference of 2 perfect squares

Step-by-step explanation:

Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation

In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.

For example, we have;

x² - 5² = 11

We subtract 11 from both sides to get;

x² - 5² - 11  = 11 - 11

x² - 36 = 0

x² - 6² = 0

(x - 6) × (x + 6) = 0

Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.

Answer:

$0.50 per pint

Step-by-step explanation:

First, we need to convert cups to pints.

There are 2 cups in 1 pint. We are given 8 cups, which is 4 times 2. So, we multiply 1 pint by 4:

1 * 4 = 4 pints

There are 4 pints in 8 cups.

We also know that 8 cups cost $2, which also means that 4 pints cost $2.

To find the cost per pint, we divide 2 by 4:

2 / 4 = $0.50

Thus, the price is $0.50 per pint.

Answer:

Temperature of the water

Step-by-step explanation:

In every study, there must be a dependent variable and an independent variable. The effect of the independent variable on the dependent variable is monitored by carefully manipulating the independent variable and observing the response it produces on the dependent variable.

In this study, the independent variable is the temperature of the water while the dependent variable is plant growth. The various temperatures of the water used to water the plant will after its growth.

Answer:

x = 68 degrees

Step-by-step explanation:

Step 1: We know this is a isosceles triangle

Since we know it is a isosceles triangle it has 2 of the same angle so the unknown side(not x) is 59

Step 2: Use the 2 angles to find 'x'

Angles in a triangle add up to 180 so we subtract 59 x 2 from 180 to get 68

Therefore angle x is 68 degrees

Answer:

Step-by-step explanation:

This is because u have to do the math - LOL

So

- an isosceles has 2 same sides. The pic shows an isosceles triangle

- 2 sides are the same which is 4

- 1 side is different and is 1.5

Same length = Same angles

So

- 4 = 4

- 56 = 56

Total angle - angle 1 - angle 2 = angle 3 or ?

- Total angle = 180

- Angle 1 = 56

- Angle 2 = 56

- Angle 3 = ?

180 - 56 - 56 = 68

Hello!

        Part A            

Peter can use the fact that 10% of 87 is 8.70 to find the amount he would save because 40% is just 4 times bigger than 10% so he can take 8.70 from to total of the coat 4 times to find out how much it cost.

        Part B            

Using the same method we know that 10% of 64 is 6.40 so we subtract that from the price of the coat 4 times to find out how much it cost

64 - 6.40 = 57.6

57.6 - 6.40 = 51.2

51.2 - 6.40 = 44.8

44.8 - 6.40 - 38.4

The price of the coat is $38.4
