Answer:

(1, 5) and (5.25, 3.94)

Step-by-step explanation:

The archway of the main entrance of a university is modeled by the quadratic equation : y = -x^2 + 6x  

The university is hanging a banner at the main entrance at an angle defined by the equation 4y = 21 - x

Now we are supposed to find At what points should the banner be attached to the archway.

So, we are supposed to find the intersections points of the two given equations.

Refer the attached figure

y = -x^2 + 6x -- Black line

4y = 21 - x -- Red line

Thus the intersection points of given equations are : (1, 5) and (5.25, 3.94)

Hence the banner be attached at (1, 5) and (5.25, 3.94) to the archway.

A building has an entry the shape of a parabolic arch 74 ft high and 28 ft wide at the base as shown below.
sergiy2304 [10]
The equation of a parabola with vertex at (h,k) is 
y=a(x-h)²+k

vertex isi at (0,0)

y=a(x-0)²+0
y=a(x)²
y=ax²
find a

we see that one point is (14,-74)
x=14 and y=-74

-74=a(14²)
-74=196a
divide both sides by 196
-37/98=a

the equation is 

y= \frac{-37}{98} x^2

It is 4.7 km from Lighthouse A to Port B. The bearing of the port from the lighthouse is N73°E. A ship has sailed due west from
Gennadij [26K]

Answer:

correct option is  C. 3.7 km

Step-by-step explanation:

given data

A to Port B = 4.7 km

lighthouse = N73°E

lighthouse = N31°E

solution

we get here first  \angle B and  

here

\angle A = 90 - 73 = 17°

\angle B =  73 - 31 = 42°

and

sum of all angle 180° so

\angle A +  

17° + 42° +  \angle C = 180°  

solve it we get

\angle C = 121°

Now we use here sin law that is

\frac{b}{sinB} = \frac{c}{sinC}   ........................2

put here value and we get

\frac{b}{sin42} = \frac{4.7}{sin121}  

solve it we get

b = 3,7 km

so correct option is  C. 3.7 km
