Classify the following triangle. Check all that apply.

V125BC [204]

Acute < 90
Right = 90
Obtuse > 90
This triangle is 104 degree so it is obtuse.

Isosceles = 2 same size
Scalene = no same size
Equilateral = all same size
You can see their is mark on 2 sides so it would be isosceles

Hey please help meeeeeeeeeeeeeeeee please do atleast 2 questions

Paraphin [41]

Answer:

2. 88, 3. 40, 4. 48, 5. 20

Step-by-step explanation:

first multiply&divide, then calculate from left to right

2. 5 · 4² + (2 · 3 + 2) = 5 · 16 + 6 + 2 = 88

3. (4 + 3)² - 12 + 3 = 49 - 12 + 3 = 40

4. 64 ÷ 4 · 3 = 16 · 3 = 48

5. 3² - 4 + 5 · 3 = 9 - 4 + 15 = 20

Write the equation in standard form. Identify the important features of the graph:

Lerok [7]

Answer:

Standard form: $\left(x-\dfrac{9}{2}\right)^2+(y+5)^2=\dfrac{121}{4}.$

This equation represents the circle with the center at the point $\left(\dfrac{9}{2},-5\right)$ and the radius $r=\dfrac{11}{2}.$

Step-by-step explanation:

Consider expression $x^2+y^2-9x+10y+15=0.$

First, form perfect squares:

$(x^2-9x)+(y^2+10y)+15=0,\\ \\\left(x^2-9x+\dfrac{81}{4}\right)-\dfrac{81}{4}+(y^2+10y+25)-25+15=0,\\ \\\left(x-\dfrac{9}{2}\right)^2+(y+5)^2=10+\dfrac{81}{4},\\ \\\left(x-\dfrac{9}{2}\right)^2+(y+5)^2=\dfrac{121}{4}.$

This equation represents the circle with the center at the point $\left(\dfrac{9}{2},-5\right)$ and the radius $r=\dfrac{11}{2}.$

if michelle rollerblade around a circular track with a radius of 80 meters, how far does she skate? use 3,14 for pie. round to t

crimeas [40]

Circumference of a circle formula is 2 $\pi$ r

2 × $\pi$ × 80
=160 × <span> $\pi$
=502.4 m

She skates 502.4 m.</span>
