what is 2+2, 1+1, and 4+4?

Answer:

it is the third one

Step-by-step explanation:

just trust the

process

Answer:

last one

Step-by-step explanation:

In every function, there can be only one value in the range (only y value) for each value in the domain (each x value). In the graph shown in the last graph, there are two y values for each value of x.

Answer:

[tex]15.75 {cm}^{3} [/tex]

Step-by-step explanation:

Convert m to cm,

0.045m =4.5cm

0.034m = 3.5cm

0.01m = 1cm

Volume = 4.5 cm × 3.5 × 1 = 15.75 cm3

or, 2z + 2z - 64° = 180°

or, 4z = 180° + 64°

or, 4z = 244°

or, z = 61°

The value of z is 61°.

Answer:

B. 2 círculos, 1 rectángulo

Working with the right hand side (RHS):

Recall the half-angle identities,

sin²(x/2) = (1 - cos(x))/2

cos²(x/2) = (1 + cos(x))/2

so that

RHS = tan²(x/2)

RHS = sin²(x/2) / cos²(x/2)

RHS = (1 - cos(x)) / (1 + cos(x))

Multiply the numerator and denominator by 1 - cos(x).

RHS = (1 - cos(x)) / (1 + cos(x)) • (1 - cos(x)) / (1 - cos(x))

RHS = (1 - cos(x))² / (1 - cos²(x))

Recall that

sin²(x) + cos²(x) = 1

so that

RHS = (1 - cos(x))² / (1 - cos²(x))

RHS = (1 - cos(x))² / sin²(x)

Expanding the numerator yields

RHS = (1 - 2 cos(x) + cos²(x)) / sin²(x)

RHS = 1/sin²(x) - 2 cos(x)/sin²(x) + cos²(x)/sin²(x)

RHS = 1/sin²(x) - 2 cos(x)/sin(x) • 1/sin(x) + cos²(x)/sin²(x)

and by definition of csc and cot,

RHS = csc²(x) - 2 cot(x) csc(x) + cot²(x)

as required.

Answer:

  -1

Step-by-step explanation:

From the graph, the y-coordinate of the circled point on the y-axis is the value of f(0). (The y-axis has equation x=0.) That coordinate is -1, so f(0) = -1.

__

From the equation, substituting x=0 makes all of the x-terms disappear, leaving only the constant.

  f(0) = -0 +0 -1

  f(0) = -1

In order to use x2 procedures, each expected cell value of a one- or two-way table must contain a value of at least five. So, option (1) is correct.

"The Chi-Square distribution table is a table that shows the critical values of the Chi-Square distribution. To use the Chi-Square distribution table, you only need to know two values: The degrees of freedom for the Chi-Square test. The alpha level for the test (common choices are 0.01, 0.05, and 0.10)".

In the given statements,

We need to analyze which statement is true regarding the Chi-square table.

In order for the Chi-square test to be considered trustworthy, each cell of your expected contingency table must have a value of at least five.

Hence we can conclude that in order to use x2 procedures, each expected cell value of a one- or two-way table must contain a value of at least five. So, option (1) is correct.

Answer:

Step-by-step explanation:

We can find the distance by using the distance formula.

d= √(x2-x1) ² + (y2-y1)²

For points (x1 = 2, y1 = -6) and ( x2 = -3, y2 = 6)

d= √(-3-2)² + (6 -(-6))², add and subtract what is inside of the parenthesis

d= √(-5)² + ( 12)², square the positive and negative number and get a positive

d= √25 + 144, add the numbers under the square root

d = √169, use the fact that 13*13= 169 to solve the square root

d= 13

Miles = 15 1/10

Miles = 151/10 miles

Hour = 1/3 hour

Av = 151/10 miles / 1/3 hour

Av = 151/10 × 3 / 1/3 × 3

Av = 453/10 miles / hour

Av = 45,3 mil / h

Answer:

no solution

Step-by-step explanation:

5 + 2(3 + 2x) = x + 3(x + 1) ← distribute parenthesis on both sides

5 + 6 + 4x = x + 3x + 3 , simplify both sides

11 + 4x = 4x + 3 ( subtract 11 from both sides )

4x = 4x - 8 ( subtract 4x from both sides )

0 = - 8 ←  false statement

This indicates the equation has no solution

Step-by-step explanation:

I used the point slope form to get the y intercept

Hello !

Answer:

[tex]\boxed{ \begin{gathered} \sf \star\ \ y=11x+62 \\ \sf\star\ \ Slope : 11\\\sf \star\ \ y-intercept: 62 \end{gathered}}[/tex]

Step-by-step explanation:

The line pass through the two following points :

The slope-intercept form of a line is of the form [tex]\sf y=mx+b[/tex] where m is the slope and b is the y-intercept.

We're looking for the two coefficients m and b.

Let's replace x and y with their values :

[tex]\begin{cases}\sf 7=-5m+b \\\sf -4=-6m+b\end{cases}[/tex]

We get a system of two equations to solve.

Let's subtract the second line from the first one and solve for m :[tex]\sf 7-(-4)=-5m-(-6m)+b-b\\\iff \sf 7+4=-5m+6m\\\iff \boxed{\sf m=11}[/tex]

Let's substitute 11 for m in the first equation :

[tex]\sf 7=-5\times11+b\\\iff \sf 7=-55+b\\\iff \boxed{\sf b=62}[/tex]

The slope-intercept form of the equation is [tex]\sf y=11x+62[/tex].

The slope is 11.

The y-intercept is 62.

Answer:

y=-23/7;y=-19/7;y=-15/7

Step-by-step explanation:

when x is -2 then y is;

2(-2)-7y=19

-4-7y=19

-7y=23 divide both sides by -7

y=-23/7

when x=0 then y is;

2(0)-7y=19

-7y=19

y=-19/7

when x=2 then y is;

2(2)-7y=19

4-7y=19

-7y=15

y=-15/7
