Answers

Answer 1

Given:

The graph of two function f(x) and g(x).

The expression is:

[tex]-1\cdot f(-8)-4\cdot g(4)[/tex]

To find:

The value of the given expression.

Solution:

From the given graph, it is clear that

[tex]f(-8)=-5[/tex]

[tex]g(4)=3[/tex]

Substitution [tex]f(-8)=-5[/tex] and [tex]g(4)=3[/tex] in the given expression, we get

[tex]-1\cdot (-5)-4\cdot 3[/tex]

[tex]=5-12[/tex]

[tex]=-7[/tex]

Therefore, the value of the given expression is -7.

Whats the missing leg?

Answers

60km

Explanation:
Pythagorean theorem
A(2)+B(2)=C(2)
X(2)+32(2)= 68(2)
Plug that into Desmos and you will get 60

Answer:

a = 60km

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

a² + 32² = 68²

a² + 1024 = 4624

*subtract 1024 from both sides to isolate a² *

a² + 1024 - 1024 = 4624 - 1024

a² = 3600

*square root both sides to isolate a*

√(a²) = √3600

a = 60km

Answer:

A has the largest surface area.

Step-by-step explanation:

Surface Area of A = 2(10*3.5) + 2(10*4) + 2(4*3.5)

= 178 in^2.

For B:

Area = 2(12*3.2) + 2(12*2.8) + 2(2.8*3.2)

= 76.8 + 67.2 + 17.92

= 161.92 in^2.

What is a triangle?

A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.

Given that, in Δ​NMP, m∠MNP =45°​, MN =7.5 feet, and MP=5 feet.

A triangle has six elements – 3 sides and 3 angles. To construct a unique triangle, 3 elements out of six elements are required under a certain combination.

So, with the given elements we can draw a triangle.

Therefore, one triangle can  drawn with the given information.
