ANSWER:9.50
Because if it is 5 or above u round up and the value you are looking for is the tenth so you look at the hundredths column to see if it goes up or down. Sorry if this doesn't make sense

In ΔUVW, the measure of ∠W=90°, the measure of ∠U=40°, and WU = 1.8 feet. Find the length of UV to the nearest tenth of a foot.

Dmitry_Shevchenko [17]

Answer: 2.3

Step-by-step explanation:

1.8

\cos 40=\frac{1.8}{x}

cos40=

1.8

x\cos 40=1.8

xcos40=1.8

Cross multiply.

\frac{x\cos 40}{\cos 40}=\frac{1.8}{\cos 40}

cos40

xcos40

cos40

1.8

Divide each side by cos 40.

x=\frac{1.8}{\cos 40}=2.3497\approx 2.3\text{ feet}

cos40

1.8

=2.3497≈2.3 feet

Calculate the axis of symmetry in the equation Y = (x+1) (x-4)

algol [13]

Answer:

Every parabola has a turning point called the axis of symmetry,so for this question you just have to find the turning points

x turning point= -b/2a,and the y turning point is gotten by replacing the value of x in the equation

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

=x^2-3x-4

a is 1,b is -3 and c is -4

x= -(-3)/2(1)

=1.5

and y=x^2-3x-4

=1.5^2-3(1.5)-4

= -6.25

therefore the axis of symmetry is (1.5,-6.25)

I hope this helps
