Can someone explain this plz and make sure u round to the nearest tenth

bonufazy [111]

Step-by-step explanation:

According to figure,Taking angle 49° as reference angle,we have

b=26

h=x=?

Now,

$\cos49 = \frac{b}{h} \\ \cos49 = \frac{26}{x} \\ 0.66 = \frac{26}{x} \\ 0.66x = 26 \\x = \frac{26}{0.66} \\ x = 39.39 \\ x = 39.4$

A tree surgeon reduces the height of a beech tree by 32%.

Jobisdone [24]

Let original Hieght be X

reduction = 32% = 32/100 X

new hieght = 4.42 m

now, 4.42 = X + 32/100 X

4.42 = 132/100 X

X = 4.42 * 100 / 132

X = 3.34 m

Original Hieght = 3.34 m

Subtract and simplify (-y^2-3y-5)-(-3y^2-7y+4)

VikaD [51]

[ Answer ]

$\boxed{2y^{2} \ + \ 4y \ - \ 9 }$

[ Explanation ]

(-y $^{2}$ - 3y - 5) - (3y $^{2}$ - 7y + 4)

[Remove Parenthesis]

-y $^{2}$ - 3y - 5 - (-3y $^{2}$ - 7y + 4)

-(-3y $^{2}$ - 7y + 4): 3y $^{2}$ + 7y - 4

-y $^{2}$ - 3y - 5 + 3y $^{2}$ + 7y - 4

[Simplify] -y $^{2}$ - 3y - 5 + 3y $^{2}$ + 7y - 4: 2y $^{2}$ + 4y - 9

= 2y $^{2}$ + 4y - 9

$\boxed{[ \ Eclipsed \ ]}$
