Algebra I

Step-by-step explanation:

Step 1: Define

We are given a graph of a quadratic function f(x).

Step 2: Evaluate

f(-3) is x = -3 for the function f(x). According to the graph, when x = -3, y = -9.

∴ f(-3) would equal -9.

The value of f(-3) from the graph of the quadratic function is -9

A polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables. Polynomials are classified based on degree as linear, quadratic, cubic etc.

A quadratic equation is a polynomial of degree 2.

The value of f(-3) can be obtained from the graph. From the graph, the value of f(-3) is -9

Período, t = 3 meses = 3/12

Usando la relación:

Equidad en el documento = Valor nominal (1 - rt)

Equidad en el documento = $ 25000 (1 - 0.25 * 0.09)

Answer:

x is equal to give

Hope am correct

Answer:

x = 5.

Step-by-step explanation:

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

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

x^2 + x = x^2 + 3x - 10

x = 3x - 10

-2x = -10

x = 5.

Answer:

X = -2

Step-by-step explanation:

4x + 2 = x3

Subtract 2 from both sides:   4x = x3 -2

Subtract x3 from both sides: 4x - 3x = -2

This leaves 1x = -2 which can also be written as x = -2

x = -2

Answer:

61% is the answer

Step-by-step explanation:

for paper 1:

[tex] \frac{75}{100} \times 60 = 45[/tex]

for paper 2:

[tex] \frac{55}{100} \times 140 = 77[/tex]

For paper 1, hisham's score is 45 out of 60

For paper 2, hisham's score is 77 out of 140

Therefore, his total score is 122 out of 200.

Therefore his total percentage score is now,

[tex] \frac{122}{200} \times 100 = 61[/tex]

Answer:

the answer is 5x - 3y = 30!!

Answer: x = 16.9

Concept:

Here, we need to know the idea of basic trigonometry.

Sine = Opposite / Hypotenues = O / H

Cosine = Adjacent / Hypotenues = A / H

Tangent = Opposite / Adjacent = O / A

Solve:

Angle θ = 50°

Opposite = x

Hypotenues = 22

Given formula

Sine = Opposite / Hypotenues

Substitute the value into the formula

sin (50) = x / 22

Multiply 22 on both sides

sin (50) × 22 = x/22 × 22

x = 22 sin (50)

x = 16.9

Answer:

1) b) r = 7

2) e) 82

Step-by-step explanation:

Progressão aritmética:

Em uma progressão aritmética, a diferença entre termos consecutivos é sempre a mesma, chamada de razão.

O n-ésimo termo de uma PA é dado por, tomando o primeiro termo como referência:

[tex]a_n = a_1 + (n-1)r[/tex]

Tomando o m-ésimo termo como referência, tem-se que:

[tex]a_n = a_m + (n-m)r[/tex]

1) Se o 5o e o 9-o termos de uma PA são, respectivamente, 40 e 68, então a razão r da progressão é:

[tex]a_5 = 40, a_9 = 68[/tex]. Então:

[tex]a_n = a_m + (n-m)r[/tex]

[tex]68 = 40 + 4r[/tex]

[tex]4r = 28[/tex]

[tex]r = \frac{28}{4} = 7[/tex]

Então a resposta correta é dada pela alternativa b.

2) Inserindo-se 6 números entre 72 e 107, de modo que a sequência (72, a2, a3, a4, a5, a6, a7 ,107) seja uma progressão aritmética, tem-se a3 igual a:

O primeiro termo é [tex]a_1 = 72[/tex] e o oitavo termo é [tex]a_8 = 107[/tex]. Com isso, é possível encontrar a razão.

[tex]a_n = a_1 + (n-1)r[/tex]

[tex]107 = 72 + 7r[/tex]

[tex]7r = 35[/tex]

[tex]r = \frac{35}{7} = 5[/tex]

Então, o terceiro termo é:

[tex]a_3 = a_1 + 2r = 72 + 2(5) = 82[/tex]

Logo, a resposta correta é dada pela alternativa e.

Answer:

99.7%

Step-by-step explanation:

Note that 92 and 128 are 3 standard deviations from the mean

The emperical rule or the  68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean

95% of outcomes are within 2 standard deviations from the mean

99.7% of outcomes are within 3 standard devations from the mean

This is 3 standard deviations so the answer is 99.7

9/7 is equivalent to 18/14 or 27/21 or 36/28 etc

Answer:

p/100*m

Step-by-step explanation:

Ok so first off, we know that,

percent means out of 100

therefore,

p/100 *of* (means multiplication in math) m  

So if we would replace *of* with multiplication, the problem would look like this

p/100 * m  and that would be your answer.

the reason we do not simplify it further is because it only asks for the algebraic expression, not the final result!

Cheers! I hope this helps and you can understand now.

An expression is defined as a set of numbers, variables, and mathematical operations. The given statement p% of m can be written in the form of an expression as pm/100.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given statement p% of m can be written in the form of an expression as shown below,

p% of m

p% × m

= (p/100) × m

= (p × m)/100

= pm/100

Answer:

adult $8.00

child $5.50

Step-by-step explanation:

Let the price of 1 adult ticket = x.

Let the price of 1 child ticket = y.

2x + 4y = 38

3x + 3y = 40.5

Multiply the first equation by 3. Multiply the second equation by -2. Then add them.

         6x + 12y = 114

(+)      -6x - 6y = -81

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

                  6y = 33

y = 33/6

y = 5.5

2x + 4y = 38

2x + 4(5.5) = 38

2x + 22 = 38

2x = 16

x = 8

Answer:

adult $8.00

child $5.50

Answer:

An adult ticket is $8.00 and a child's ticket is $5.50.

Step-by-step explanation:

We form a system of 2 equations and solve them.

Let a be the price of adult ticket and c the price of a child's.

2a + 4c = 38         (A)

3a + 3c = 40.5      (B)

Multiply equation A by 3 and equation B by -2:

6a + 12c = 114

-6a - 6c = -81        Adding these 2 equations:

0 + 6c = 33

c = 33/6 = 5.5.

Now we substitute for c in equation A:

2a + 4(5.5) = 38

2a = 38 - 22

2a = 16

a = 6.

Let's now check these results by substitution in equation B:

3a + 3c = 40.5

3(8) + 3(5.5) = 24.0 + 16.5 = 40.5

- so it checks out.

[tex]y^2 = 55[/tex]

[tex]x^2 = 80\\x = \sqrt{80} \\x= 4\sqrt{5}[/tex]

Answer:

A

Step-by-step explanation:

The x value of the center = 0

The y value of the center = 220/2 + 11 = 110 + 11 = 121

so the center is at (0,121)

The radius is 220/2 = 110

The equation of the Ferris Wheel is

x^2 + (y - 121)^2 = 110^2

x^2 + (y - 121)^2 = 12100

Step-by-step explanation:

PLACE YOUR GRAPH TOWARDS A MIRROR.....

The new coordinate of the image after the reflection in the x-axis is [tex]P'(3, 4)[/tex].

Reflection is a type of rigid geometrical transformation that maintains the object's size and shape, unlike other transformations such as dilation, which changes the size of the shape, reflection results in congruent images.

The rule for the reflection over the x axis is "if the point (x, y) reflected in axis the it becomes (x, -y).

According to the given question.

We have a coordinates of the image of P(3, -4).

So, when the coordinates of the image is reflected in the x-axis then the x coordinate remains same but the y coordinate changes its sign from negative to positive and we get the new coordinate of the image that is [tex]P'(3, 4).[/tex]

Hence, the new coordinate of the image after the reflection in the x-axis is [tex]P'(3, 4)[/tex].
