Answer:

sinΘ = [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex]

The opposite is 24, but we require the hypotenuse h

Using Pythagoras' identity

h² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )

h = [tex]\sqrt{625}[/tex] = 25

Thus

sinΘ = [tex]\frac{24}{25}[/tex]

Answer:

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape.

Answer: 72.9 in^3

Step-by-step explanation:

The softball is a sphere, and we know that the volume of a sphere is:

V = (4/3)*pi*r^3

where pi = 3.14 and r is the radius.

We also know that the radius is half the diameter, and the diameter is 5.2 in

r = 5.2in/2 = 2.6in

Then the volume is:

V = (4/3)*pi*(2.6in)^3 = 72.9 in^3

The correct answer is 73.6 in^3

Answer:

the answer is C

Step-by-step explanation:

Rotate 90 degrees counterclockwise , the translate three units to the left

Option C is the correct transformation to transform ABCD to A'B'C'D'.

Rotation

Rotate the square ABCD counterclockwise about the origin. Sides AD and BC of square ABCD will become parallel to the sides A'D' and B'C' respectively of the square A'B'C'D'. The square ABCD is, thus, oriented the same way as the square A'B'C'D'.

Vertical Translation

After the rotation, the side AB is 1 unit above the y-axis, which is the same as that of the square A'B'C'D'. So, the vertical position of the square ABCD is the same as that of the square A'B'C'D'.

Horizontal Translation

The side AD of the square ABCD is 5 units to the left of the x-axis. The side A'D' of the square A'B'C'D' is 8 units to the left of the x-axis. So, translate the square ABCD to the left by 3 units to coincide with the position of A'B'C'D'.

Thus, to obtain A'B'C'D' from ABCD first rotate it by 90° counterclockwise then, translate it to the left by 3 units.

Answer: 26

Step-by-step explanation:

From -10 to 0 will be 10

1 to 16 are 16

Answer:

Step-by-step explanation:

There are several things you need to know in order to write the absolute value equation for a situation. First is how to formulate what you need. The absolute value equation follows the formatting:

| x - midpoint | = the distance between the midpoint and one of the endpoints.

That means we also need to be able to find the midpoint of -10 and 16. Finding the midpoint is finding the middle, which is the same as finding an average of the 2 numbers.

[tex]M=\frac{-10+16}{2}=3[/tex]

So the midpoint is 3. The distance between 3 and either one of the endpoints is going to be the same, by definition of the midpoint of the 2 numbers. The distance between 3 and 16 is 13 units. The distance between 3 and -10 is also 13 units. So, to put this into an absolute value equation,

| x - 3 | = 13

Answer:

x= -3,      x = 1

Step-by-step explanation:

Zeros are values of x, when f(x) = 0.

0=(x+3)(x-1)

x+3 = 0,  x - 1=0

x= -3,      x = 1

Answer:

x = -3, x = 1

Step-by-step explanation:

To determine the zeroes of the factored quadratic equation, we need to look back at its definition. The zeroes are a function are specific x-values that result in a y-value of 0.

In this case, we want the numbers inside of the parantheses to equal 0. If we substitute in x = -3, we get (0)(x - 1), and we know that is just 0. Similarly, if we substitute in x = 1, we get (x + 3)(0), and we know that is just 0.

As such, these are your solutions.

Answer: [tex]1\dfrac{4}{21}[/tex] .

Step-by-step explanation:

Given problem : [tex]\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)[/tex]

First we convert mixed fraction into improper fractions as

[tex]-5\dfrac{5}{6}=-\dfrac{5\times6+5}{6}=-\dfrac{30+5}{6}=-\dfrac{35}{6}\\-4\dfrac{9}{10}=-\dfrac{10\times4+9}{10}=-\dfrac{40+9}{10}=-\dfrac{49}{10}[/tex]

Now , plug these values in the given expression , we get

[tex]\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)=-\dfrac{35}{6}\div\left(-\dfrac{49}{10}\right)\\\\=\dfrac{-35}{6}\times\dfrac{-10}{49}\ \ \ [\text{By Property of fraction}]\\\\=\dfrac{350}{294}\\\\=\dfrac{25}{21}=1\dfrac{4}{21}[/tex]

Hence, the answer is [tex]1\dfrac{4}{21}[/tex] .

Answer: The number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .

Step-by-step explanation:

Given word = "EQUATION"

Total letters = 8

Total Vowels (EUAIO)=5

Total number of ways to arrage letters = 8!

Number of ways to arrange vowels in alphabetical order = 5!

Then, The number of ways that all the vowels are in alphabetical order will be :

[tex]\dfrac{8!}{5!}=\dfrac{8\times7\times6\times5!}{5!}=336[/tex]

Hence, the number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .

Total cause of the laptop

429.99+25.7994= 455.79

No, the cost of the laptop after applying sales tax is $455.79.(option c)

A sales tax is a consumption tax imposed by the government on the sale of goods and services.

We have,

Lewis saved dollar for a new laptop = 450 dollar

Laptop sticker price = 429.99 dollar

Sales tax rate = 6%

According to the question

Sales tax rate of 429.99 dollar

=429.99 × 6/100

= 25.7994

Total cause of the laptop

429.99+25.7994= 455.79

Hence, the cost of the laptop after sales tax is 455.79 dollar

Answer:

C

Step-by-step explanation:

yeah its C

The requried function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
The x-intercept is the point where the graph of a function intersects the x-axis. At this point, the value of y is 0. To find the x-intercept of each function, we set y equal to 0 and solve for x.

A. f(x) = 3x – 9

0 = 3x – 9

3x = 9

x = 3

B. f(x) = 1/x + 4

0 = 1/x + 4

-4 = 1/x

x = -1/4

C. f(x) = √(x+1)

0 = √(x+1)

x = -1

D. f(x) = x²

0 = x²

x = 0

Therefore, the function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.

Answer:

Step-by-step explanation:

since there is no sales tax,

Amount of money used to pay

= change + total price of items bought

Let's find the total price of the items she bought.

Chicken

1 package ----- $12.36

2 packages ----- 2($12.36)= $24.72

Broccoli

1 pound ----- $1.98

½ pound ----- $1.98 ÷2= $0.99

Milk

1 gallon ----- $3.49

Total amount paid

= $24.72 +$0.99 +$3.49

= $29.20

Thus, amount of money Susan used to pay

= $29.20 +$0.80

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = [tex]\frac{h}{c}[/tex]

c = [tex]\frac{h}{\text{tan}47}[/tex]

c = [tex]\frac{4.8}{\text{tan}47}[/tex]

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = [tex]\frac{h}{b}[/tex]

b = [tex]\frac{h}{\text{tan}37}[/tex]

b = [tex]\frac{4.8}{1.0724}[/tex]

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = [tex]\frac{h}{a}[/tex]

a = [tex]\frac{h}{\text{tan}27}[/tex]

a = [tex]\frac{4.8}{0.5095}[/tex]

a = 9.42 m
