Answer:

<h2>NO.</h2><h2>15, 35, 40 it will make an obtuse triangle.</h2>

Step-by-step explanation:

If a ≤ b ≤ c are sides of a triangle, then a + b > c.

We have a = 15, b = 35, c = 40.

Check:

15 + 35 = 50 > 40 CORRECT

These sides can be the sides of a triangle.

If a ≤ b ≤ c are sides of a triangle, then

if a² + b² = c², then it's a right triangle

if a² + b² < c², then it's an obtuse triangle

if a² + b² > c², then it's an acute triangle

Check:

15² + 35² = 225 + 1225 = 1450

40² = 1600

1450 < 1600 ⇒ 15² + 35² < 40²

Therefore it's an obtuse triangle

Answer:

NO.

Step-by-step explanation:

If it is a right triangle then by the Inverse of the Pythagoras Theorem:

40^2 = 35^2 + 15^2

Testing:

40^2 = 1600

35^2 + 15^2 = 1225 + 225 = 1450

So the answer is NO>

After you subtract both sides by 4. How can you solve for 3x in this equation?

Nataly [62]

Answer:

Step-by-step explanation:

Once you subtract both sides, the 4 is gone then the 10 is subtracted into a 6. You go to the 3x, and just like what you did to the 4 you do the opposite and divide the 3 by itself and the 6 by 3 as well.

If cosθ=2/3 find cscθ using identities. This is in quad. 1.

laiz [17]

Step-by-step explanation:

cos θ = 2/3

$\quad \twoheadrightarrow\sf {cos \; \theta = \dfrac{Base}{Hypotenuse} } \\$

Hence, base = 2 units and hypotenuse = 3 units.

$\quad \twoheadrightarrow\sf { H^2 = B^2 + P^2} \\$

$\quad \twoheadrightarrow\sf { P^2 = H^2 - B^2} \\$

$\quad \twoheadrightarrow\sf { P^2 = (3)^2 - (2)^2} \\$

$\quad \twoheadrightarrow\sf { P^2 = 9- 4} \\$

$\quad \twoheadrightarrow\bf { P = \sqrt{5}} \\$

Now, we know that :

$\quad \twoheadrightarrow\sf {cosec \; \theta = \dfrac{Hypotenuse}{Perpendicular} } \\$

$\quad \twoheadrightarrow\bf{cosec \; \theta = \dfrac{3}{\sqrt{5}} } \\$

Therefore, the required answer is 3/√5.

WILL GIVE BRAINLIEST FOR A CORRECT ANSWER:

guapka [62]

Answer:

Solution:

the boat's speed in still water: x

The speed with current: (x+3)

The speed against current: (x-3)

The equation is

3(x+3) = 4(x-3)

x = 21 mph

The distance = 3*(21+3)= 72 miles

I choose (A)

Match the types of well formed formulas with the expressions. Negation Conjunction Disjunction Conditional Biconditional A. T &l

nikklg [1K]

<h3>Answers:</h3>

A. T <-> U is a biconditional
B. (A & B) v (C & D) is a disjunction
C. R -> ~S is a conditional
D. P & Q is a conjunction
E. ~(R v P) is a negation

========================================

Explanations:

A biconditional is anything in the form A <-> B. This is a compact way of saying (A -> B) & (B -> A). We replace A and B with logical statements.
Disjunctions are of the basic form A v B. The "v" basically means "or".
Any conditional is of the form "if... then...". For example, "if it rains, then it gets wet outside" is a conditional. In terms of logic symbols, we write A -> B to mean "if A, then B".
Conjunctions are whenever we combine two logical statements with an "and" or an ampersand symbol. The basic form is A & B
Negations are the complete opposite of the original. If the original is P, then the negation is ~P, which is read as "not P".

The inverse of f(x)=x^2 is also a function t/f

vodka [1.7K]

The Answer is false.

the function f (x) = x 2 is NOT one-to-one, and therefore cannot have an inverse.Therefore, the function f (x) = x 2 does NOT have an inverse.
