Answer:

21 m²

Step-by-step explanation:

Area of a trapezoid is given by the formula:

A = (a+b)/2×h

(where h is the vertcial height, and a and b are the parallel lines)

Substituting values given gives us:

A = (5+9)/2×3

A = 14/2×3

A = 7×3

A = 21

Units will be m² as this is area.

Answer:

21

Step-by-step explanation:

the formula is:

[(base1+base2)/2]*height
[(9+5)/2]*3

Answer:

There is a strong correlation with one outlier and this forms a pattern going up

Trust me I had trouble and my teacher showed me how to get it.

Answer:

There are 6 points and one outlier in this graph. Excluding the lowest and highest points, four dots are left to set up the trend line. Among these points, we can see the dots lowering when moving to the right side.

This means the trend line is negative.

For correlation, it is clear that the four dots are well organized in descending manner. Because of this, the graph will still have a high negative correlation even with the outlier(s). Therefore the plots in this graph have a strong negative correlation.

Answer:

C

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, 4 ) and (x₂, y₂ ) = (0, 22 )

m = [tex]\frac{22-4}{0-(-8)}[/tex] = [tex]\frac{18}{0+8}[/tex] = [tex]\frac{18}{8}[/tex] = [tex]\frac{9}{4}[/tex]

the line crosses the y- axis at (0, 22 ) ⇒ c = 22

y = [tex]\frac{9}{4}[/tex] x + 22 ← equation of line

Answer:

b = c = 75°

Step-by-step explanation:

b and 105° are adjacent angles and sum to 180° , then

b + 105° = 180° ( subtract 105° from both sides )

b = 75°

b and c are vertically opposite angles and are congruent , so

c = b = 75°

Answer:

Step-by-step explanation:

Each x-value corresponds to only a single y-value.

Here, the relation is : y = 5x

This relation is injective, meaning it is a one-to-one function.

Answer:

Yes

Step-by-step explanation:

Each value in the domain corresponds to exactly one value in the range.

Answer:

1st option

Step-by-step explanation:

theequation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

5x + 2y = - 10 ( subtract 5x from both sides )

2y = - 5x - 10 ( divide terms by 2 )

y = - [tex]\frac{5}{2}[/tex] x - 5 ← in slope- intercept form

with slope m = - [tex]\frac{5}{2}[/tex]

The values of a through e that make these two relations inverses of each other. a = b = c = d = e = are:

This refers to the function of a function f that undoes the operation of f. The inverse of f exists if and only if f is bijective. It is also known as reciprocals.

Now, if we assume that y = g(x) and y = h(x) are inverse of each other, where g(x) and h(x) are two different functions.

Then if a = g(b) then b = h(a).

Now, in the given table from the complete question, we would have

a = - 3.8, b = - 2.6, c = 1.7, d = 4.4 and e = 1.0 as the values of the function in inverse.

Answer:

Look to explanation

Step-by-step explanation:

The question says the original mosaic  is surrounded by a 3 inch by 5 inch frame.  The length has 5 squares & the width has 3 squares, so that means each square is an inch long.

1.  Perimeter is adding up how long all the sides are.  So for the original you add 3 + 5 + 3 + 5 = 16 inches

2.  Area is length x width, so we multiply 3 x 5 = 15 inches squared

3.  Since each square is an inch, to find the length we add up all the squares & we get 10.  Then we do the same for the width & get 6.  To figure perimeter, we add up all the sides  10 + 6 + 10 + 6 = 32 inches

4.  Area is length x width, so 10 x 6 = 60 inches squared

5.  For the original we needed 16 inches of steel.  For the larger one, we needed 32 inches.  32 inches is 2x bigger than 16.

6.  For the original we had an area of 15 inches squared.  For the larger one we had 60 inches squared.  60 is 4x bigger than 15.

Answer:

[tex]1\frac{89}{100}[/tex] m

Step-by-step explanation:

The formula to find the area of a rectangle: [tex]l * b[/tex], where [tex]l[/tex] is the length and [tex]b[/tex] is the breadth.

1) Substitute the values into the formula.

[tex]12\frac{3}{5} = 6\frac{2}{3} * b[/tex]

2) Change it to an improper fraction and solve for [tex]b[/tex].

[tex]\frac{63}{5} = \frac{20}{3} * b[/tex]

[tex]\frac{3}{20}[/tex] * [tex]\frac{63}{5}[/tex] = [tex]b[/tex]

[tex]\frac{189}{100} = b[/tex]

3) Change it to a mixed fraction because the length is in a mixed fraction. To do it, do a long division.

Solving

Answer:

y = [tex]\frac{\pi}{3}[/tex]

Step-by-step explanation:

using the addition formula for sine

sin(x + y) = sinxcosy + cosxsiny

then

sinxcosy + cosxsiny = [tex]\frac{1}{2}[/tex] sinx + [tex]\frac{\sqrt{3} }{2}[/tex] cosx

for the 2 sides to be equal , then

cosy = [tex]\frac{1}{2}[/tex] and siny = [tex]\frac{\sqrt{3} }{2}[/tex]

then

y = [tex]cos^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex]

and

y = [tex]sin^{-1}[/tex] ( [tex]\frac{\sqrt{3} }{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex]

thus y = [tex]\frac{\pi }{3}[/tex]

[tex]\\ \rm\Rrightarrow sin(x+y)=\dfrac{1}{2}sinx+\dfrac{\sqrt{3}}{2}cosx[/tex]

[tex]\\ \rm\Rrightarrow sinxcosy+cosxsiny=\dfrac{1}{2}sinx+\dfrac{\sqrt{3}}{2}cosx[/tex]

[tex]\\ \rm\Rrightarrow cosy+siny=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]

[tex]\\ \rm\Rrightarrow cos\dfrac{\pi}{3}+sin\dfrac{\pi}{3}=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]
