Answer:

9s = 378t      

is the same as  (9 x 42)   etc...

Step-by-step explanation:

I don't have the choice of answers of what is being said as proportional but an example is here below of what numbers are multiples of 42 and therefore found its proportion this way.

10s = 420t       (10 x 42)

9s = 378t         (9 x 42)   etc...

8s = 336t

7s = 294t

6s = 252t

5s = 210t    (5 x 42)

4s = 168t    etc....

The function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

f(x) = √x

f(x) is a parent function.

a parent function is the core representation of a function type without manipulations such as translation and dilation.

We have to find the function h(x) which is obtained by transforming the function f(x)

From the given graph, the function f(x) is moved up about 2 units and the shifted left of 5 units

h(x) =√x+2 - 5

Hence, the function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5

Answer:

i think its b.24 minutes

Step-by-step explanation:

sorry if im wrong

Answer:

Samantha spent 24 minutes on language arts.

Step-by-step explanation:

So, 60% = 3/5.

Since Samantha spent 40 minutes in total for homework, the 40 minutes would be the denominator. Let's have the variable "x" equal how many minutes she spent on language arts. If we line up the fractions, it will be like this:

3/5 = x/40

Since we know 5 x 8 = 40, we would also multiply the numerator by 8.

3 x 8 =24.

So, Samantha spent 24/40 minutes on ELA, which is 60% of the total time.

The type of transformation must the line segment have undergone if Sandra transforms a line segment such that the new image is longer than the original line segment, is dilation, so option A is correct.

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.

Given:

Sandra transforms a line segment such that the new image is longer than the original line segment,

The above transformation is an example of dilation, as in dilation the image can be transformed into a large image or a small image,

Thus, the given transformation is an example of dilation.

Step-by-step explanation:

(jk−1) ÷j

[(-4)(-0.8) -1] ÷ (-4)

=[ 3.2 -1] ÷ (-4)

=2.2 ÷ (-4)

= -0.55

The solution of the expression "[tex]\frac{jk-1}{j}[/tex]" is "-0.55".

The given values are:

→ [tex]\frac{jk-1}{j}[/tex]

By putting the value of "j" and "k" in the given expression, we get

→ [tex]\frac{(-4)(-0.8)-1}{-4}[/tex]

By solving the brackets, we get

→ [tex]\frac{3.2-1}{-4}[/tex]

→ [tex]\frac{2.2}{-4}[/tex]

Since both cot(θ) and cos(θ) are positive, it follows that sin(θ) is also positive:

cot(θ) = cos(θ)/sin(θ) > 0   ===>   sin(θ) > 0

Recall the Pythagorean identity:

sin²(θ) + cos²(θ) = 1

Multiplying both sides by 1/sin²(θ) yields another form of the identity,

sin²(θ)/sin²(θ) + cos²(θ)/sin²(θ) = 1/sin²(θ)

1 + cot²(θ) = csc²(θ)

so that

csc(θ) = + √(1 + cot²(θ))

csc(θ) = √(1 + (3/2)²)

csc(θ) = √13/2

By definition of cosecant, we have

csc(θ) = 1/sin(θ)

so that

sin(θ) = 2/√13

Then using the Pythagorean identity once more, we have

cos(θ) = + √(1 - sin²(θ))

cos(θ) = √(1 - (2/√13)²)

cos(θ) = 3/√13

so that, by definition of secant,

sec(θ) = 1/cos(θ)

sec(θ) = √13/3

Answer:

28, 3x 8

Step-by-step explanation:

Step-by-step explanation:

The first part of solving the area is multiplying the rectangle. So you do 15*18 which is 270. Then to solve a triangle you make it a square/rectangle. So it would be 8*15 which is 120. Because the length is the length of the rectangle and the width is shown on top. Then because it’s a rectangle not a triangle you divide by 2 because you were adding half to it when you were making it a rectangle. So it’s 120/2 which is 60. And 270+60 is 330. So the area is 330. To get the perimeter you add all the sides together. And because one of the sides is not added but half of the bottom line is the same length as the top so it would be 18+ the 8 on the top which is 26. So 15+18+17+26 is 76. So the perimeter is 76

So the answer is the bottom one. P=76 and A=330

We have that  the fourth term of an arithmetic sequence is

From the question we are told

What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?

A) 78

B) 32

C) 14

Generally the equation for the  arithmetic sequence  is mathematically given as

[tex]a_4=a_1+(n-1)d[/tex]

Therefore

For seventh term

[tex]5=23+(6)d\\\\d=5-23/(6)\\\\d=-3[/tex]

Answer:

56

Step-by-step explanation:

Arithmetic mean is simply the sum of the all the number present divide by the total number.

From the question, we obtained the following information:

The arithmetic mean = 5.6

Total number present = 10

Sum of the numbers =?

Arithmetic mean = sum of the numbers / total number

Sum of the numbers = arithmetic mean x total number

Sum of the numbers = 5.6 x 10 = 56

The sum of the other four numbers is equivalent to -200.

Given is that the arithmetic mean of ten numbers is -10. The sum of six of the numbers is 100.

We can write -

{a + b + c + d + e + f + g + h + i + j}/10= - 10

{a + b + c + d + e + f + g + h + i + j} = - 10 x 10

{a + b + c + d + e + f + g + h + i + j} = - 100    .... Eq{1}

and

{a + b + c + d + e + f} = 100             .... Eq{2}

We can write Eq{1} as -

{a + b + c + d + e + f} + {g + h + i + j} = - 100

100 + {g + h + i + j} = - 100

{g + h + i + j} = - 100 - 100

{g + h + i + j} = - 200

Therefore, the sum of the other four numbers is equivalent to -200.
