What type of chart/graph must have all of its smaller parts add up to one whole?

svet-max [94.6K]

Step-by-step explanation:

<h3>A perimeter is either a path that encompasses/surrounds/outlines a shape or its length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden.</h3>

↓↓↓

<h3>The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 50 ft × 50 ft your fence is 200 ft long.</h3>

Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartF

Firdavs [7]

The length 2.3 and 7.8 units

We have given that ΔABC, c = 5. 4, a = 3. 3, and measure of angle A = 20 degrees.

<h3>What is the formula for low of cosine?</h3>

The Law of Cosines, which tells us

$a^{2}=b^{2} +c^{2} -2bccosA$

giving us a quadratic equation for b we can solve. But let's do it with the Law of Sines as asked.

$\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}$

We have c,a,A so the Law of Sines gives us sin C

$sinC=\frac{csina}{a} =\frac{5.4sin20}{3.3} =0.5597$

There are two possible triangle angles with this sine, supplementary angles, one acute, one obtuse

$C_{a}=arcsin(0.5597)=34.033^{0}$

$C_{0}=180-C_{a} =145.96^0$

Both of these make a valid triangle with A=20°. They give respective B's:

$B_{a}=180-A-C_{a} =125.96^0$

$B_{0}=180-C_{0} =14.033^0$

So we get two possibilities for b:

$b=\frac{asinB}{sinA} \\\\b_{a} =\frac{3.3sin125.96}{sin 20} \\\\b_{a}=7.8\\\\ b_0=2.3$

2.3 units and 7.8 units

Therefore we get the length 2.3 and 7.8 units

Answer: 2.3 units and 7.8 units

Let's check it with the Law of Cosines:

There's a shortcut for the quadratic formula when the middle term is 'even.'

Looks good.

Find the x-intercept and y-interceppt of each graph

Paha777 [63]

Answer:

11.) y-int:(0,1); x-int:(1,0)

12.) y-int:(0,8); x-int:(4,0)

13.) y-int:(0,-9); x-int:(-3,0)

14.) y-int:(0,-5); x-int:(-2.5,0)

Step-by-step explanation:

For each equation, first you have to graph it. Then to find the y-intercept, you mark and check where your line of your equation intersects the y-axis. To find the x-intercept, you mark and check where the line of your equation intersects the x-axis. The y-intercept always will have the coordinates of x=0 and the x-intercept always will have the coordinates of y=0.
