What is the formula for the area of a triangle?

SashulF [63]

The formula to find the area of a triangle is :

1/2 base*height

For instance:

base=4 cm

height=5cm

area of traingle=1/2*b*h

 =1/2*4*5

 =10cm^2

Hope it helps...

cos theta = 4/5, 0˚< theta < 90˚ use the information given to find sin2theta, cos2theta, and tan 2theta

NikAS [45]

First calculate $\sin\theta$ .

$\sin^2\theta+\cos^2\theta=1\\\\\sin^2\theta=1-\cos^2\theta\\\\\sin^2\theta=1-\left(\dfrac{4}{5}\right)^2\\\\\\\sin^2\theta=1-\dfrac{16}{25}\\\\\\\sin^2\theta=\dfrac{9}{25}\quad|\sqrt{(\dots)}\\\\\\\sin\theta=\sqrt{\dfrac{9}{25}}\\\\\\\boxed{\sin\theta=\dfrac{3}{5}}$

We take positive value of sinθ because 0° < θ < 90°
Now we could calculate sin2θ, cos2θ and tan2θ:

$\sin2\theta=2\sin\theta\cos\theta=2\cdot\dfrac{3}{5}\cdot\dfrac{4}{5}=\dfrac{2\cdot3\cdot4}{5\cdot5}=\dfrac{24}{25}\\\\\\\cos2\theta=\cos^2\theta-\sin^2\theta=\left(\dfrac{4}{5}\right)^2-\left(\dfrac{3}{5}\right)^2=\dfrac{16}{25}-\dfrac{9}{25}=\dfrac{7}{25}\\\\\\
\tan2\theta=\dfrac{\sin2\theta}{\cos2\theta}=\dfrac{\frac{24}{25}}{\frac{7}{25}}=\dfrac{24\cdot25}{7\cdot25}=\dfrac{24}{7}=3\dfrac{3}{7}$

Which iS an equation of the line with a slope of 1/4 and a y-intercept of -2?

qaws [65]

Answer: C

Step-by-step explanation:

Convert all equations into slope-intercept form, the equation must have a slope of 1/4 and a y-intercept of -2

A) x + 4y = -8

4 ÷ (4y = - x - 8) ÷ 4

y = -1/4x - 2 --> Not the correct equation because slope is negative

B) 4x - y = 2

-1 ÷ (- y = 2 - 4x) ÷ -1

y = 4x - 2 --> Not the correct equation as the slope is not a fraction

C) x - 4y = 8

-4y = 8 - x

-4 ÷ (x - 4y = 8) ÷ -4

y = 1/4x - 2 --> Therefore, C is the correct equation

The tiles below represent the polynomial 2x^2 + 7x+6.

MakcuM [25]

Answer:

C (x+2)(2x+3)

Step-by-step explanation:

You can count in the picture that in the top part there are two x's (2x) and three ones (3). So the top would be (2x+3)

On the left side there is one x (x) and two ones (2). It would be (x+2).

So combine them together, it would be (x+2)(2x+3).
