Answer:

BC ≈ 12.6 m

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan31° = \frac{opposite}{adjacent} = \frac{AB}{BC} = \frac{7.6}{BC} ( multiply both sides by BC )

BC × tan31° = 7.6 ( divide both sides by tan31° )

BC = \frac{7.6}{tan31} ≈ 12.6 m ( to 3 sf )

Part C of Jim and his dad are building a rectangular flower bed.
charle [14.2K]
I gotchu

The perimeter is 35. If we were to change the width, which is one of the dimensions of the flower bed, The perimeter will change. This means that perimeter will no longer be 35. So in order to keep the perimeter as it is, if we change one dimension, we must also change the other.

Let's solve for the length, using the formula to see how much the length changes from.

p = 2l + 2w

35 = 2l + 2(15)

35 = 2l + 30

5 = 2l

2.5 = l


We must increase the length from 2.5 feet. This is because decreasing one dimension will decrease the perimeter. But if we increase the other dimension as well, it will restore the perimeter to where is was initially.

I need to factor this expression
soldier1979 [14.2K]

Answer:

( 5x + 1 ) ( x - 4 )

Step-by-step explanation:

5x² - 19x - 4

= 5x² + x - 20x - 4

= x ( 5x + 1 ) - 4 ( 5x + 1 )

= ( 5x + 1 ) ( x - 4 )

Hence, factorized.

How many x intercepts does the graph of y =|x-2|+12
WARRIOR [948]

Answer:

The graph not have x-intercepts

Step-by-step explanation:

we know that

The x-intercept is the value of x when the value of y is equal to zero

we have

y=\left|x-2\right|+12

This is the equation of an absolute value in vertex form open upward

The vertex is the point (2,12)

The y-coordinate of the vertex is above the x-axis and the graph open upward

That means ----> The graph do not intersect the x-axis

therefore

The graph not have x-intercepts

<u><em>Verify</em></u>

For y=0

substitute in the equation

0=\left|x-2\right|+12

\left|x-2\right|=-12 ----> is not true

The left side of the equation cannot be a negative number

so

The equation not have solution for y=0

therefore

The graph not have x-intercepts

see the attached figure to better understand the problem
