Step-by-step explanation:

Think of the archway as a semicircle with a radius of 28/2 = 14

The diagonal of the truck is like the hypotenuse of a right triangle with legs of 7 and 13

c² = a² + b²

c² = 7² + 13²

c² = 49 + 169

c² = 218

c = 14.76

Since the diagonal of the truck is greater than the radius of the arch the truck will NOT pass without damage

Answer:

x =  -4 ± i4

Step-by-step explanation:

This is a quadratic equation with coefficients {1, 8, 32}.  We apply the quadratic formula to solve for x.  The first step is to find the 'discriminant,' b^2 - 4 ac, which here is (8)^2 - 4(1)(32), or 64 - 128, or -64.  

A negative discriminant indicates that this quadratic has two unequal complex roots.  

                               -b ± √(b^2 - 4ac)

The formula is x = ----------------------------

                                         2a

which, when evaluated at a = 1, b = 8 and c= 32, yields

                               -8 ± √(-64)

The formula is x = ----------------------------

                                         2(1)

or:

                               -8 ± i√64                

The formula is x = -----------------   = x =  -4 ± i4

                                        2

I think that's ur answer

Explanation:

y = 5 because the long leg is exactly sqrt(3) times that of the short leg.

The short leg is always opposite the 30 degree angle.

The hypotenuse x is twice that of y, so x = 2y = 2*5 = 10

All of these rules only apply to 30-60-90 triangles. You can use trig ratios as an alternative route.

Lila's height is

Metre is the standard measure of height.

Fatima's height, F = 1.27m

Charlotte's height, C=0.89m

Lila is taller than Charlotte by half the difference between Fatima's height and Charlotte's height, so we can write

Lila's height, L = C+((F-C)/2)

L=0.89+((1.27-0.89)/2)=1.08

Hence, Lila is 1.08 metres tall.

T he pattern shows that the number of hours of daylight per day is higher in the summer and lower in the winter. This pattern is caused by the tilt of Earth's axis. At some points in Earth's orbit around the Sun, the tilt causes one hemisphere to lean toward the Sun while the other one is tilted away.

Step-by-step explanation:

You have an angle bisector in AD. That means the sides are in proportion to to BD and DC

It's much easier just to look at the proportion.

AB / BD = AC/DC

18 / (3x - 3) = 15/(x + 5)              Cross multiply

18*(x + 5) = 15 (3x - 3)                Remove the brackets

18x + 90 = 45x - 45                  Switch the sides.

45x - 45 = 18x + 90                  Subtract 18x from both sides

-18x           -18x

27x - 45 = 90                           Add 45 to both sides

      +45    45

27x = 135

x = 5

But that's not the answer (even though it is correct). You want BD

BD = 3x - 3

BD = 3*5 - 3

BD = 15 - 3

Answer

132 degrees

Step-by-step explanation:

Strategy: Find angle DEB and using that fact that DEB + DEF is 180 degrees to find angle DEF

The sum of the four angles of any quadrilateral is 360 degrees.

Since three angles are given, we can use that to find the fourth.

360-(147+93+72)=size of angle DEB. Solving, you get angle DEB is 48.

Also, knowing that segment BF is a straight line, it means that angle DEB + angle DEF is equal to a straight angle (180 degrees).

DEB+DEF=180

48+DEF=180

DEF=180-48=132 degrees.

Thus, angle DEF is equal to 132 degrees.

Answer:

y + 16 = -1(x + 3)²

Step-by-step explanation:

Looking at the graph, parabola vertex opens upwards with x intercepts as -5 and -1.

Thus, the line of symmetry will be;

x = (-5 + (-1))/2 = -3

Looking at the graph we can see that the vertex when traced to the x - coordinate will be 3 which is same with what we got.

Now, the general form of the equation will be;

y - h = a(x - k)²

where (k,h) is the vertex coordinate

Thus, k = -3

So;

y - h = a(x - (-3))²

>> y - h = a(x² + 6x + 9) =

>> y = ax² + 6ax + 9a + h

When, x = 0

y = 9a + h

From the graph, we can see that the y-intercept is y = -25

Thus;

9a + h = -25

From the graph, h which is the y-coordinate of the vertex = -16

Thus;

9a - 16 = - 25

9a = -25 + 16

9a = -9

a = -9/9

a = -1

Thus, the equation is;

y - (-16) = -1(x - (-3))²

>> y + 16 = -1(x + 3)²
