There is no solution for this equation. :)

Please mark as brainliest!! :)

Check the picture below.

5+4+10+9+14 = 42.

Step-by-step explanation:

For a parabola y = ax² + bx + c, the vertex occurs at x = -b / (2a).

For f(x), a = -2, b = 0, and c = 9.  So the vertex is at:

x = -0 / (2×-2)

x = 0

At x=0:

f(0) = -2(0)² + 9

f(0) = 9

The maximum of g(x) is at 11.

So g(x) has a greater maximum value than f(x).

Answer:

2 eggs and 6 ounces of flour.

Step-by-step explanation:

To calculate this, we have to find 1/3 of 6 eggs and 18 ounces of flour separately.

So to calculate 1/3 of 6 eggs, multiply 6 by 1/3, which is to say divide 6 by(reciprocal) .Then you get 2 eggs.

Then similarly to calculate 1/3 of 18 ounces of flour, multiply 18 by 1/3, or divide it by 3. Then you get 6 ounces of flour.

So your answer is 2 eggs and 6 ounces of flour.

Step-by-step explanation:

Lateral Area:

We have five congruent triangles with base = 7in and height h = 9in.

The formula of an area of a triangle:

[tex]A_triangle=\dfrac{bh}{2}[/tex]

Substitute:

[tex]A_\triangle=\dfrac{(7)(9)}{2}=\dfrac{63}{2}=31.5\ in^2[/tex]

The Lateral Area:

[tex]L.A.=5A_\triangle\to L.A.=5\cdot31.5=157.5\ in^2[/tex]

Surface Area:

S.A. = L.A. + B

L.A. - lateral area

B - area of a base

The base is the regular pentagon. The formula of an area:

[tex]B=\dfrac{a^2}{4}\sqrt{25+10\sqrt5}\approx1.72048a^2[/tex]

Substitute a = 7in:

[tex]B\approx1.72048(7^2)=84.303552\ in^2\approx84.3\ in^2[/tex]

The Surface Area:

[tex]S.A.=157.5+84.3=241.8\ in^2[/tex]

The answer is 27 i think..

This triangle is a right triangle.

We know that the sum of the angles is 180°.

So:

90° + (x+23)°+ (x+13)° = 180°

90 + (x+23) + (x+13) = 180

(x+23)+(x+13) = 180-90

(2x+36) = 90

(2x) = 90-36

(2x) = 54

x = (54/2)

x = 27

=> x = 27

Answer:

(-2, -3)

Step-by-step explanation:

2x + 1 = 3x + 3

minus 3 from both sides

2x - 2  = 3x

minus 2x from both sides

-2 = x

then plug in -2 for x

y = 2(-2) + 1

y = -4 + 1

y = -3

(-2, -3).

Answer:

9x^(3/2)=9 √(x^3 )  

Step-by-step explanation:

We are given

9x^(3/2)

We have to write the expression in radical form, for that the power has to be a multiple of ½

=9x^(3*1/2)

As we can see now the power is a multiple of 1/2. ½ will convert to square root while 3 will become the power of radicand.

So, 9 will remain outside of the square root while x will be inside the square root while having power 3.

=9 √(x^3 )

Hence,

9x^(3/2)=9 √(x^3 )

Answer:

fish 1 dollar

castle 6 dollars

Step-by-step explanation:

4x + y = 10

4x + 2y = 16

Multiply the first equation by -1

- 4x - y = -10

4x + 2y = 16

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

0x  +y   = 6

y = 6

This means the castle costs 6 dollars

Substitute this into the first equation

4x+y =10

4x+6=10

Subtract 6 from each side

4x+6-6=10-6

4x=4

Divide by 4

4x/4=4/4

x=1

This means each fish costs 1 dollar

So x=1 the answer is 1

Final answer:

To convert 134.7 grams to milligrams, multiply by the conversion factor of 1000, resulting in 134700 milligrams.

Explanation:

To complete the statement 134.7 g = blank mg, one needs to understand the conversion between grams and milligrams. There are 1000 milligrams (mg) in 1 gram (g). When converting from a larger unit to a smaller unit, we multiply by the conversion factor. Therefore, multiplying 134.7 g by 1000 gives us the equivalent number of milligrams.

134.7 g × 1000 = 134700 mg

Thus, 134.7 g is equal to 134700 mg.

Answer:

x = 25

Step-by-step explanation:

4x = 100

Divide each side by 4

4x/4 = 100/4

x = 25

Answer:

Step-by-step explanation:

Given

f(x) = - 2x² + 4x - 2

To find the y- intercept set x = 0

f(0) = 0 + 0 - 2 = - 2 ← y- intercept

The equation of the axis of symmetry is of the form x = c

where c is the value of the x- coordinate the line goes through.

Given the equation in standard form

with a = - 2, b = 4 then the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex] = - [tex]\frac{4}{-4}[/tex] = 1

Equation of axis of symmetry is x = 1

Answer:

The y-intercept is -2

The equation of the axis of symmetry is x = 1

Step-by-step explanation:

* Lets revise the general form of the quadratic function

- The general form of the quadratic function is f(x) = ax² + bx + c,

 where a, b , c are constant

# a is the coefficient of x²

# b is the coefficient of x

# c is the y-intercept

- The meaning of y-intercept is the graph of the function intersects

 the y-axis at point (0 , c)

- The axis of symmetry of the function is a vertical line

  (parallel to the y-axis) and passing through the vertex of the curve

- We can find the vertex (h , k) of the curve from a and b, where

 h is the x-coordinate of the vertex and k is the y-coordinate of it

# h = -b/a and k = f(h)

- The equation of any vertical line is x = constant

- The axis of symmetry of the quadratic function passing through

  the vertex then its equation is x = h

* Now lets solve the problem

∵ f(x) = -2x² + 4x - 2

∴ a = -2 , b = 4 , c = -2

∵ The y-intercept is c

∴ The y-intercept is -2

∵ h = -b/2a

∴ h = -4/2(-2) = -4/-4 = 1

∴ The equation of the axis of symmetry is x = 1

Given a=33 and c=44,

b = 29.10326 = 11√7

Step-by-step explanation:

The following is one way to perform the calculation. It may not be the best way.

b =√c2 - a2

=√442 - 332

=√847

=29.10326 = 11√7

∠α =arcsin(a/c)

=arcsin(33/44)

=arcsin(0.75)

=0.84806 rad = 48.59° = 48°35'25"

∠β =arcsin(b/c )

c

=arcsin(29.10326442171/44)

arcsin(0.66143782776615)

=0.72273 rad = 41.41° = 41°24'35"

h =a×b/c

=33 × 29.10326442171/44

=21.82745

area =a×b/2

=33 × 29.10326442171/2

=480.20386=363√7/2

perimeter =a+b+c

=33 + 29.10326442171 + 44

=106.10326

inradius =a×b/a+b+c

=960.40772591645/106.10326442171

=9.05163

circumradius =c/2

=44/2

=22

Answer:

No there cannot be the same number of stickers on each page.

Step-by-step explanation:

If you want to find out how many stickers need to be in every page to be even you would add all the stickers up. 6+6+9+10+11= 42. Take the 42 and divide it by 5 to see how many stickers would go in each page. This will give you 8.4. However since this number is a decimal it can't be split evenly in whole stickers for each page. Meaning that it wouldn't be possible for each page to have a evenly distributed number of stickers per each page.

Answer:

C) 1/4,3/8,2/5

Step-by-step explanation:

First of all, let's rewrite all the fractions listed as decimal numbers:

[tex]\frac{2}{5}=0.400[/tex]

[tex]\frac{1}{4}=0.250[/tex]

[tex]\frac{3}{8}=0.375[/tex]

So the correct order from least to greatest should be

0.250, 0.375, 0.400

Which corresponds in fractional form to

1/4, 3/8, 2/5

So the correct option is

C) 1/4,3/8,2/5

The correct set of fractions ordered from least to greatest is C) 1/4, 3/8, 2/5.

To determine the set of fractions ordered from least to greatest, we need to compare them by finding a common denominator or converting them to decimals.

Let's convert the fractions to decimals:

Next, we order the decimals from smallest to largest:

Therefore, the correct order from least to greatest is: C) 1/4, 3/8, 2/5.

Step-by-step explanation:

If we want to share the money in equal parts, we have to consider that Eli has 9 shares, Freda has 13 shares and Geoff has 18 shares. So, in total, we have to split the money in

[tex]9+13+18 = 40[/tex]

parts. So, each part is

[tex]\dfrac{800}{40} = \dfrac{80}{4} = 20[/tex]£

Now, we distribute the shares:

Answer:

Eli gets £180

Freda gets £260

Geoff gets £360

Step-by-step explanation:

First, you need to make a ratio comparing their ages.

9 : 13 : 18 which is Eli : Freda : Geoff

Next, you need to work out the sum their ages (9+13+18) which is 40.

Then you divide the £800 (the amount that is being shared) by the sum of their ages 800÷40 which gives £20.And finally you need to multiply 20 by each section of the ratio.

So, 9×20 : 13×20 : 18 ×20 but then you need to simplify to get 180: 260 : 360.

Option B. 5P5 × 20P15

Step-by-step explanation:

It is very important to remember that the second grade students are sitting in the front row, therefore, it is only necessary to organize 15 first grade students in 20 seats.

Permutations allow you to calculate the number of ways in which m objects can be arranged in n positions.

The permutation of m in n is written as:

nPm

Where n is the number of elements and m are chosen.

The way in which the 5 second grade students can be organized in the 5 seats is from the first row is:

5P5

Then, the number of ways in which 15 first-year students can be organized into 20 seats is:

20P15

Then, the number of ways to organize all students on the bus is the product of both permutations

Answer:

0.61

Step-by-step explanation:

The average rate of change of H(s) in the closed interval [ a, b ] is

[tex]\frac{H(b)-H(a)}{b-a}[/tex]

here [ a, b ] = [ 80, 100 ]

H(b) = H(100)

= 0.003 × 100² + 0.07 × 100 - 0.027

= 30 + 7 - 0.027 = 36.973

H(a) = H(80)

= 0.003 × 80² + 0.07 × 80 - 0.027

= 19.2 + 5.6 - 0.027 = 24.773

Hence

average rate of change = [tex]\frac{36.973-24.773}{100-80}[/tex] = [tex]\frac{12.2}{20}[/tex] = 0.61

(B) The employee subtracted the wrong percent's.

Answer:

b she substracted wrong

Step-by-step explanation:

Step-by-step explanation:

Because the length of ST is calculated using pythagorean theorem:

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

Where the square of the hypotenuse is equal to the sum of squares of the other two sides of a right triangle. In this case, the hypotenuse is ST and the other two sides are distances between S and T over the X and Y axis. Those are easily calculated:

[tex]x = |sx - tx| \\ y = |sy - ty| [/tex]

Where x is the distance between S and T over X axis and Y distance over Y axis, sx and tx are X coordinates of S and T, sy and ty are Y coordinates of S and T.

Using that formula, you get that y = 17 and x = 8.

Back to the pythagorean theorem, if we put those number in the formula of the pythagorean theorem, we get something like this:

[tex] {c}^{2} = {x}^{2} + {y}^{2} \\ {c}^{2} = {8}^{2} + {17}^{2} = 64 + 289 \\ {c}^{2} = 353 \\ c = \sqrt{353} [/tex]

And finally, the correct answer is in fact 353.
