What is the constant term of -3x^4-7x+2
emmasim [6.3K]

Answer:

The equation written in the standard form is written as

ax^4 + bx+c

where a and b are the coefficients of the second-order and first-order term, while c is the constant term.

The equation we have in this problem is

By comparing (1) with (2), we immediately see that

A = -3x^4

B = 7x

C = 2

Step-by-step explanation:

Hope this helps :)

Help me with my math**50 pts** i mark brainliest**
xenn [34]

Answer:

3) Reflexive Property

4) SAS

Step-by-step explanation:

<h2>ST ≅ TS</h2>

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

  • Example: a = a  
  • In this case, it could be seen as ST ≅ ST because they have/are the same side(s).
<h2>RST ≅ UTS </h2>

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

  • Example: RST ≅ UTS (both have S and T)
  • Can be seen as RST ≅ UST as well to make their similarity more evident.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

26. Law of sines, please give a step by step explanation
Stels [109]

Answer:

  174.6 ft

Step-by-step explanation:

It can be helpful to draw a diagram of the triangle we're concerned with. (See attached.)

We know the angle at the end of the shadow inside the triangle is 52°-22° = 30°. We assume the tree is growing straight up out of the hillside, so its angle with the hill inside the triangle is 90°+22° = 112°. Then the remaining angle between the shadow and the tree at the top of the tree is ...

  180° -30° -112° = 38°

Now, we have the angle opposite the tree, and the angle opposite the known side length of the triangle (215 feet along the hill, AC in the diagram). This is enough information to usefully use the Law of Sines.

  c/sin(C) = a/sin(A)

  c = a(sin(C)/sin(A)) = (215 ft)(sin(30°)/sin(38°)) ≈ 174.6 ft

The height of the tree is about 174.6 feet.

What is a right angle degree
Luba_88 [7]

A right angle degree is always 90 degrees, or 1/4 of the full amount of degrees, which is 360. 90 degrees, is also pi/2 radians, which you will learn in trigonometry and pre-calc.
