Find the value of x to the nearest tenth?

Mathematics

First we should find the base length of the triangle (let's call this y) using Pythagoras' Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and a and b are the other two sides
6^2 = 4^2 + y^2
36 = 16 + y^2
y^2 = 20
y = 4.47 (to two decimal places)

Now this y-value that we have found is actually half of x, which we can see since the length x is perpendicular to h, and thus:
4.47 = 0.5x
x = 4.47/0.5 = 8.9 (to the nearest tenth)
Thus the answer is C

Which graph represents -5x+3y is equal to or greater than 9
kifflom [539]

Answer:

First, transform the given equation into the slope intercept form.

-5x + 3y >= 9

3y >= 5x + 9

y >= 5/3x + 3


Then graph the line y = 5/3x + 3. Draw a solid line with y intercept 3 and slope of 5/3.

Finally, shade everything that is above the line.

If a translation of T2, –7(x, y) is applied to ΔABC, what are the coordinates of B'?
NikAS [45]

The coordinates of B' are 3 and -12. so option D is correct (3, -12)

<h3>How to find the coordinates of B'?</h3>

The point P(x, y) may undergo translation to form P' by using a defined translation rule :

If given the rule T(a, b) synch that P undergoes translation on T; then we will have P'(x+a; y+b)

Therefore,

The point B has its coordinates as B(1, - 5)

Translation rule, T(2, - 7) then the coordination of B after undergoing transformation according to T2;

B(1, - 5) - - - > T(2, - 7) - - - - > B'(1+2 ; - 5+-7)

= B'(3, -12)

Hence, the coordinates of B' are 3 and -12. so option D is correct.

The height of an acorn falling out of a tree is given by h=-16t+b. If an acorn takes 1 second to fall to the ground what is the
ollegr [7]
From the equation given above,
                               h = -16t + b
If it takes 1 second to fall to the ground, we substitute 1 to t of the equation,
                               h = -16(1) + b
Adding 16 to both sides of the equation, the value of b would be
                               h + 16 = b
or 
                                 b = h + 16
