Solve this<br><br> 4 ∙ 7 1/2 ∙ 1 3/5

bixtya [17]

Step-by-step explanation:

$= 7 \frac{1}{2} .1 \frac{3}{5}$

$= \frac{ \red{\cancel{15}}}{ \blue{ \cancel{2}}} . \frac{ \blue{\cancel{8}}}{ \red{\cancel{5}}}$

$= \frac{3}{1} . \frac{4}{1}$

$= 12$

The ABC Toy Company is creating two similar pieces for a board game, as shown below. How could the toy maker confirm that the pi

kati45 [8]

Answer:

The company can confirm that the pieces are similar by verifying that the relationship between the sides of the parts in the drawing created with MS Visio, of the diagram in a similar question found online, are;

$\dfrac{\overline {RS}}{\overline {XZ}} = \dfrac{\overline {RT}}{\overline {XY}} = \dfrac{\overline {ST}}{\overline {ZY}}$

Step-by-step explanation:

The definition of similarity is the quality of two or more objects having a common definitive property

Two objects in Euclidean geometry are similar if they are similar in shape and parameters of one shape can be obtained from the other by the application of a uniform scale and/or translation, reflection and rotation

The ABC toy maker could confirm that the pieces are similar by verifying that the corresponding sides of the two shapes have a common ratio

F(x) = 9 sin(x) + cot(x), −π ≤ x ≤ π find the interval of increase.

podryga [215]

We are given the function
F(x) = 9 sinx + cot x

We need to take the first derivative of the given function so,
F' (x) = 9 cos x - csc² x

Next, we equate the first derivative of the function to 0 and solve for the values of x
0 = 9 cos x - csc² x
Solving for x
x = 2.04

Picking out an arbitrary value between 2.04 and π, say 3 and substituting in F(x)
F(3) = 9 sin 3 + cot 3 = 19.55

Therefore, the interval where the function is increasing is from 2.04 to π
Consequently, the interval where the function is decreasing is from -π to 2.04<span />

Answer:

The slope is -2

Step-by-step explanation:

(0,4) (3,-2)

remeber the equation is Y2-Y1/X2-X1

Y2 = -2

Y1 = 4

X2=3

X1=0

Plug it in the euqation to see if it works
