Step-by-step explanation: PEMDAS use this ok first you do 7x7 to equal 49 then add 50 to equal 99. then do 5x5x5 to equal 125. the parentheses are gone and the 5x5x5 is gone now the problem is 125-2x3-99. to finish you multiply 2x3 to equal 6 now 125-6-99=20 answer-20

NISA [10]

Answer:

Building is 56.58 feet long.

Step-by-step explanation:

Consider the provided information.

An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads.

When the photograph is taken, the angle of elevation of the sun is 30°.

By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 98 feet long.

As we know: $\tan\theta=\frac{opp}{adj}$

The value of tan 30 degrees is $\frac{1}{\sqrt{3} }$

$\tan30=\frac{h}{98}$

$\frac{1}{\sqrt{3}}=\frac{h}{98}$

$h=\frac{98}{\sqrt{3}}$

$h=56.58$

Hence, Building is 56.58 feet long.

What is the equation of the line?<br> y=3x<br> Y=1/3x<br> Y=1/3x+2<br> Y=3x+2

Mrrafil [7]

Answer:

Y = 1/3x + 2

Step-by-step explanation:

Since the line increases by 1 unit then goes to right 3 units the line equation must have a slope of 1/3 and must have a y intercept of + 2 since the line crosses the Y axis at +2

Given the function ƒ(x) = 3x2 − 5x + 10, find ƒ(4).

Sav [38]

The right answer is Option B: f(4) = 38

Step-by-step explanation:

Given function is;

$f(x) = 3x^2-5x+10$

For finding f(4), we will put x=4 in the given function; therefore

Putting x=4 in given function,

$f(4) =3(4)^2-5(4)+10\\f(4) =(3*16)-20+10\\f(4) = 48-10\\f(4) = 38$

Therefore;

f(4) = 38 in the given function.

The right answer is Option B: f(4) = 38

Need help with this problem explain pls

Usimov [2.4K]

All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.

a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
