Final answer:

The positive solution to the equation 2x² + 25 = 73 is x = √24, which is approximately 4.9.

Explanation:

The student is asking for the positive solution to the equation 2x² + 25 = 73. To solve this, we first isolate the quadratic term by subtracting 25 from both sides of the equation, resulting in 2x² = 48. Then, we divide both sides by 2, simplifying to x² = 24. Taking the square root of both sides gives us two solutions, x = √24 and x = -√24. Since we're seeking the positive solution, we take the positive square root, which yields x = √24 or about 4.9.

Hey there!

Let's make a system of equations using x and y to find the two numbers.X is smaller and y will be larger.

x+y=98

y-4x=18

Now, let's solve the bottom equation for y so we can use substitution.

y=18+4x

Now we plug this into the first equation.

x+18+4x=98

5x+18=98

5x=80

x=16

Now, we plug this into the first equation to find y.

y=82.

So, the larger number is 82 and the smaller number is 16.

I hope this helps! Have a great day!

Answer:

x = 8

Step-by-step explanation:

Two secants drawn from an external point to the circle.

The (outside ) × (whole) of one secant is equal to the (outside) × (whole) of the other secant, that is

(x + 2)(x + 2 + 2x - 8) = (x + 1)(x + 1 + 2x - 5)

(x + 2)(3x - 6) = (x + 1)(3x - 4) ← expand both sides using FOIL

3x² - 12 = 3x² - x - 4  ( subtract 3x² - x - 4 from both sides )

x - 8 = 0 ( add 8 to both sides )

x = 8

230 is the  value of the company in 2018.

Option (B) is correct.

To find 230 represent in the function.

science that deals with the addition, subtraction, multiplication, and division of numbers.

It is given that:

The equation of a exponential growth function is equal to

[tex]V(t)=a(1+r)^{t}[/tex]

where,

V(t) is the value of the company

t is the number of years after 2018

a is the initial value or y-intercept

r is the rate of change

Put the value,

a=230

1+r=1.12

r=1.12-1=0.12

r=12%

so 230 is the value of the company when the value of t is equal to zero.

Remember that t is the number of years since 2018

Therefore ,230 is the  value of the company in 2018.

Answer:

14/45

Step-by-step explanation:

Answer:

x = -29/11 , y = 5/11

Step-by-step explanation:

-x+3y=4 ,..........(1)

3x+2y=-7 ............(2)

Solve simultaneously using elimination method

Multiply equation 1 by 3

It gives

-3x + 9y = 12

3x + 2y = -7..........(2) , add both equations

--------------------------

11y = 5

Divide both sides by 11

y = 5/11

Put value of y into equation (2)

3x +2y = -7

3x + 2(5/11) = -7

3x + 10/11 = '-7

Subtract 10/11 from both sides

3x +10/11 - 10/11 = -7  - 10/11

3x = -87/11

Divide both sides by 3

3x/3 = -87/11 ÷ 3

x = - 87/11 × 1/3

x = -29/11

Therefore x = -29/11 , y = 5/11

Answer:$48.09 please give brainliest!

Step-by-step explanation: you need to turn the percent to decimal so you move the decimal points to places to the right so the percent now is 0.25 so then you do 38.47 *0.25 =9.62 so then you add 9.62 +38.47 =48.09

Answer:

$9.62

Step-by-step explanation:

total cost= $38.47

tip            = 25% = [tex]\frac{25}{100}[/tex]

=> tip       = [tex]\frac{25}{100}[/tex] * $38.47

               ≈ $9.62 (to the nearest cent)

NOTE: the question is solely asking for the tip, therefore, there is no need to add the tip to the total.

The vertex form of a parabola is given as

[tex]y = a {(x - h)}^{2} + k[/tex]

If this parabola opens downward, then a<0.

This means for a function opening downward not to have a solution, the k value must also be negative and taking a square root of a negative number will not give real solution.

Answer:

Volume of the cylinder = [tex]7686.72\,inches^3[/tex]

Step-by-step explanation:

Radius(r) of the cylinder= [tex]12\,inches[/tex]

Height(h) of the cylinder= [tex]17\,inches[/tex]

Volume of a cylinder is :

                   [tex]\pi \times r^2\times h[/tex]

As,

          [tex]\pi =\dfrac{22}{7}=3.14[/tex]

Volume is:  

            [tex]=3.14\times (12\times 12)\times 17\\\\=3.14\times 144 \times 17\\\\=3.14\times 2448\\\\=7686.72\,inches^3[/tex]

The volume of the cylinder is: [tex]7686.72\,inches^3[/tex]                    

Problem setup:

The shape is way too complicated by itself, so I cut the shape into 5 different parts.

Please refer to the attached image or my answer will not make much sense.

Shape 1:

This is a triangle. The base is 3 and the height is 2. Thus, the area is:

[tex]A=\dfrac{1}{2}*3*2[/tex]

[tex]=3[/tex]

Shape 1 has an area of 3 square units.

Shape 2:

This shape is also a triangle. The base is 4 and the height is 2. Thus, the area is:

[tex]A=\dfrac{1}{2}*4*2[/tex]

[tex]=4[/tex]

Shape 2 has an area of 4 square units.

Shape 3:

This a unit square (the side lengths are 1).

Thus, Shape 3 has an area of 1 square unit.

Shape 4:

This shape is a rectangle. The base is 3 and the height is 4. Thus, the area is:

[tex]A=3*4[/tex]

[tex]=12[/tex]

Shape 4 has an area of 12 square units.

Shape 5:

This shape is also a rectangle. The base is 4 and the height is 2. Thus, the area is:

[tex]A=4*2[/tex]

[tex]=8[/tex]

Shape 5 has an area of 8 square units.

Total shape:

Add the areas of all 5 shapes to find the area of the shaded figure.

[tex]A=3+4+1+12+8[/tex]

[tex]=26[/tex]

The figure has a total area of 26 square units.

Side notes:

There is a way to solve this problem by only dividing this into only 3 different shapes, can you figure it out?

Answer:

-77, -78, -79

Step-by-step explanation:

let one of the integers be x

since the integers are consecutive, the other 2 integers must be

(x+1) and (x+2)

given that sum of the integers is -234,

x + (x+1) + (x+2) = -234

x + x + 1 + x + 2 = -234

3x + 3 = -234   (subtract 3 from both sides)

3x = -234-3

3x = -237  (divide both sides by 3)

x = -237 / 3

x = -79  (answer)

hence the other two numbers are

(x + 1) = -79 + 1 = -78 (answer)

and

(x+2) = -79 + 2 = -77 (answer)

Answer:

Step-by-step explanation:

let the first integer is 'x', and by adding 1 in it we get the second integer that is 'x+1', and for third integer we need to add 1 in the previous integer i.e. is 'x+1' we get 'x+2'. Now all three integers we have are

x,x+1 and x+2.

since sum or add all three integer we get -234. so

x+x+1+x+2=-234

x+x+x=3x, and 1+2=3

3x+3=-234

3x=-234-3

3x=-237

x=-237/3

now the first integer is -237/3 or -79,

second integer is -78 and third integer is -77.

for verification add all three to get -234.

-79-78-77=-234. hence proved.

Answer:

y=9

y=1

y= -7

y= -15

Step-by-step explanation:

You have to use the number in the x colum and fill in itnot te equation

y= -4x+1

Start with the first number, -2

y= -4(-2)+1          multiply -4 and -2 because of PEMDAS

y=8+1                         simplify

y=9

Now do the next number, 0

y= -4(0)+1        Multiple -4 and 0  because of PEMDAS (Anything times 0 is 0)

y=1

Now do the next number, 2

y= -4(2) + 1      Multiply -4 and 2 because of PEMDAS

y= -8 + 1       Simplify

y=-7

Now do the next number, 4

y= -4(4) +1         Multiply -4 and 4 because of Pemdas

y = -16 +1

y= -15

To round 721295.198715 to the nearest ten, we increase the tens place from 9 to 0 due to the ones place being 5, resulting in 721300.

To round the number 721295.198715 to the nearest ten, we should look at the digit in the ones place, which is 5. Since the ones digit is 5 or greater, we need to round up the tens place.

Therefore, the tens digit increases by one from 9 to 0, and all digits to the right of the tens place become zero.

Thus, 721295 rounds up to 721300 when rounded to the nearest ten.

Note that we ignore the decimal and its subsequent numbers because they do not influence the rounding of a number to the nearest ten.

Length of other two sides is 27:33

Option B

Step-by-step explanation:

Here we have , The sides of a triangle are in ratio 9:11:13.The largest side of a triangle like this is 39. Let's calculate other two sides of the second triangle:

[tex]9:11:13[/tex] is the ratio  ,largest ratio value is 13 which represents largest side ratio whose length is 39 :

⇒ [tex]13x = 39\\[/tex]

⇒ [tex]x = \frac{39}{13}\\[/tex]

⇒ [tex]x = 3[/tex]

Now, other two sides are 9 x and 11 x

i.e. [tex]9x = 9(3) = 27[/tex]

 [tex]11x = 11(3) = 33[/tex]

So, lengths of all the three sides are 27:33:39 . And, Length of other two sides is 27:33`

[tex](n+4)^{\frac{3}{5}}[/tex] is the equivalent expression for [tex]\sqrt[5]{(n+4)^{3}}[/tex].

Solution:

Given expression:

[tex]\sqrt[5]{(n+4)^{3}}[/tex]

To find the equivalent expression for the given expression.

[tex]\sqrt[5]{(n+4)^{3}}[/tex]

Using radical rule: [tex]$\sqrt[m]{a}=a^{\frac{1}{m}}[/tex]

      [tex]$=\left((n+4)^{3}\right)^{\frac{1}{5}}[/tex]

Using exponent rule: [tex]$\left(a^{b}\right)^{c}=a^{b c}[/tex]

      [tex]$=(n+4)^{3 \cdot \frac{1}{5}}[/tex]

      [tex]$=(n+4)^{\frac{3}{5}}[/tex]

[tex]\sqrt[5]{(n+4)^{3}}=(n+4)^{\frac{3}{5}}[/tex]

Hence [tex](n+4)^{\frac{3}{5}}[/tex] is the equivalent expression for [tex]\sqrt[5]{(n+4)^{3}}[/tex].

[tex]5x - 30[/tex]

Step-by-step explanation:

We want to simplify

[tex]5(x - 6)[/tex]

We use the distributive property of real numbers which says that:

[tex]a(b + c) = ab + ac[/tex]

We apply the distributive property to get;

[tex]5(x - 6) = 5 \times x - 5 \times 6[/tex]

This implies that:

[tex]5(x - 6) = 5 x - 30[/tex]

Therefore the correct answer is 5x-30
