”The total area of the frame and picture needed by the photographer = 80 in²The size of the picture that will be in the frame = 5 × 7 inchThe length of the picture = 7 inchesThe width of the picture = 5 inchesLet x represent the width of the frame, we get;

The width of the total area = The width of the picture + 2 ×

The width of the frameTherefore, the width of the total area = 5 + 2·x

The length of the total area =

The length of the picture + 2 ×

The width of the frame

Therefore, the length of the total area = 7 + 2·xWe get;

The total area = Total length × Total width 

The total area = (5 + 2·x) × (7 + 2·x) 

We are given that the total area = 80, therefore, by transitive property of equality,

we have;(5 + 2·x) × (7 + 2·x) = 8035 + 10·x + 14·x + 4·x² = 804·x² + 24·x = 80 - 35 = 45∴ 4·x² + 24·x = 45

Therefore, the quadratic equation that can be used in solving for the width is 4·x² + 24·x = 45.”

Answer:

y' = 1 / sinxcosx

Step-by-step explanation:

Given :

y = sinx + cosx / sinx - cosx

Applying quotient rule :

y' = [(sinx - cosx)(cosx - sinx) - (sinx + cosx)(cosx + sinx)] / (sinx -

cosx)²

y' = [sinxcosx - cos²x - sin²x + sinxcosx - (sinxcosx + cos²x + sin²x + sinxcosx)] / (sinx - cosx)²

y' = 2sinxcosx - 2sinxcosx - 2cos²x - 2sin²x / (sinx -cosx)²

y' = -2(sin²x + cos²x) / (sinx - cosx)²

y' = -2 / (sinx - cosx)²

y' = -2 / sin²x - 2sinxcosx + cos²x

y' = -2 / -2sinxcosx

y' = 1 / sinxcosx  [⇒ Final answer]

Answer:

A. a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right

The sequence of transformation is "a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right" option (A) is correct.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The missing figure is attached to the picture, please refer to the picture.

From the figure we can see the transformation applied on the pentagon is a 90° counterclockwise rotation around the origin, followed by a translation of Three units up and seven right

Thus, the sequence of transformation is "a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right" option (A) is correct.

Answer:

AC = 14.0

Step-by-step explanation:

We know that this is a non-right triangle, so we must use either the law of sines or law of cosines to find AC.

We can find the measure of <C using 180 - (118 + 22) = 40

Since we only know one side and all the angles, we can use the law of sines:  [tex]\frac{a}{sin A}=\frac{b}{sin B}=\frac{c}{sin C}[/tex]

[tex]\frac{24}{sin 40}=\frac{AC}{sin 22}[/tex]

Solving for AC gives us AC = 13.986826, which we can round to 14.0

The volume of the shape shown is 105π cm³

Volume is the amount of space occupied by a three dimensional shape and object.

Volume of the cone = (1/3) * π * (6/2)² * 5 = 15π cm³

Volume of the cylinder = π * (6/2)² * (16 - 5 - 6/2) = 72π cm³

Volume of the hemisphere = (2/3)π * (6/2)³ = 18π cm³

Volume of the shape = 15π cm³ + 72π cm³ + 18π cm³ = 105π cm³

The volume of the shape shown is 105π cm³

BC = 5 cm (nearest whole number)

Step-by-step explanation:

Use the sine trig ratio:

Given:

Substituting these values into the sine ratio formula:

[tex]\implies \mathsf{\sin (22.6)=\dfrac{a}{13}}[/tex]

The correlation coefficient is -0.12 and the line of the best fit is y = -0.11x + 385.50

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

From the table, the value of r:

r = -0.12

The negative correlation exist between year and time.

Since the value of r is not near the -1 or -1 we can say the relation is very weak.

The line of best fit:

y = mx + c

m = -0.11

c = 385.50

y = -0.11x + 385.50

Thus, the correlation coefficient is -0.12 and the line of the best fit is y = -0.11x + 385.50

Answer:

76

Step-by-step explanation:

5 + X = Y

Y/ 3 = 27

Substitute Y with 5 + X

(5 + X) / 3 = 27

5 + X = 81

X = 76

Answer:

76

Step-by-step explanation:

let the number be n then added to 5 is 5 + n , so

[tex]\frac{1}{3}[/tex] (5 + n) = 27 ( multiply both sides by 3 to clear the fraction )

5 + n = 81 ( subtract 5 from both sides )

n = 76

Answer:

You have to divide the diagram into 3 rectangles and add the cm

Step-by-step explanation:

suppose you have a table-like - diagram and you have to find the perimeter

first, you divide it into 3 rectangles like so.

second, you right 1st rectangle= 1cm,2cm

then continue with this method until done.

third, you add all the measurements and you get the answer

Answer:

The perimeter is 22cm

Step-by-step explanation:

So first we know that the top is 5cm, the two bottom parts are each 1cm, one of the insides is 2cm, and the right side is 4cm. So far that gives us a perimeter of 13cm. Now we need to find the unlabeled sides, so first (and it doesn't matter what side you start with) let's find the left side. Because the shape is symmetrical we can look across at the right side's measurement, and it will be the same measurement for the left side, 4cm. Next the right inside. Again, we can look to the left and we see that the left inside has a measurement of 2 cm, so the right inside will be the same, 2cm. Now for the bottom. We see that the top is 5cm, and if we were to fill in that empty space at the bottom, it would also be 5cm. We know that the two bottom pegs are each 1cm, so they're 2cm combined. If we were to fill in the rectangle, the bottom would equal 5cm. So 5-2 (for the 2cm of the bottom pegs), we get 3cm for that bottom unlabeled part. So if we add 13 to our new numbers 4, 3, and 2, we get a perimeter of 22cm.
