Answer:

6 square inches

Step-by-step explanation:

The formula for area of a triangle is:

1/2(b*h)

Therfore;

b=4, h=3

So,

1/2(4*3)

1/2(12)

=1/2 * 12

= 6 square inches

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.

Asafa runs 0.75 kilometers in 6 minutes. Jemaine runs 3,000 meters in half an hour. Who ran at a faster rate?

Lorico [155]

Answer:

Asafa ran at a faster rate

Step-by-step explanation:

Asafa's speed:

0.75 km/ 6 min = 750 m/ 6 min = 125 m/min

Jemaine's speed:

3000 m / 30 min = 100 m/min

Asafa ran at faster rate as 125 m/min > 100 m/min

Help with my homework pls Solve the compound inequality y + 7 ≥ –1 and y∕4 + 3 ≤ 5.

Marianna [84]

Answer:

-8 ≤ y ≤ 8

Step-by-step explanation:

Subtract 7 from the first one:

y ≥ -8

Subtract 3 from the second one, then multiply by 4.

y/4 ≤ 2

y ≤ 8

Now, you can write these as a compound inequality:

-8 ≤ y ≤ 8

_____

Additional comment

You basically solve these the same way you would an equation. The only difference is that multiplying or dividing by a negative number will reverse the inequality symbol:

2 > 1

-2 < -1 . . . . . multiplied above by -1.
