The number that has to fill the blank to make the trinomial a perfect square is 72x

Perfect square trinomial

From the question, we are to determine the number that makes the given trinomial a perfect square

The given trinomial is

9x² + ___+ 144

For any given trinomial ax² + bx + c, the trinomial is a perfect square if

b² = 4ac

In given trinomial,

a = 9, c = 144, b = ?

Now, we will determine the value of b

Putting the values into the equation,

b² = 4ac

b² = 4×9×144

b² = 5184

b = √5184

b = 72

Thus,

The trinomial will become 9x² + 72x+ 144

Answers

Haler ran farther than Tyler in 10 minutes. She covered an extra 0.05 miles compared to Tyler.

What is an equation?

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

Tyler can run 1 mile in 8 minutes and 20 seconds.

Time taken = 8 mins + 20 sec (0.33 min) = 8.33 minutes

Speed = distance / time = 1 mile / 8.33 = 0.12 mile per min

In 10 minutes, distance = 0.12 mile per min * 10 min = 1.2 mile

Haler is given by:

y = 8x; where y is time and x is distance.

In 10 minutes, distance = y/8 = 10/8 = 1.25 miles

Haler ran farther than Tyler in 10 minutes. She covered an extra 0.05 miles compared to Tyler.

Step-by-step explanation:

f and 78° are alternate angles and are congruent , then

f = 78

---------------------------

h and 74° are alternate angles and are congruent , so

h = 74

--------------------------

the sum of the 3 angles in the triangle = 180°

sum the 3 angles and equate to 180

78 + g + h = 180

78 + g + 74 = 180

152 + g = 180 ( subtract 152 from both sides )

How do you construct the inscribed and circumscribed circles of a triangle?

Answers

Answer:

inscribed: centered at the intersection of angle bisectors, radius = distance to one sidecircumscribed: centered at the intersection of perpendicular bisectors, radius = distance to one vertex

Step-by-step explanation:

The steps to constructing either circle start with finding the relevant center and radius. The required construction techniques are ...

bisect an angleperpendicular to a line through an external pointperpendicular bisector

Inscribed circleSummary

The incenter (center of the inscribed circle) is located at the coincidence of the angle bisectors. The radius is the perpendicular distance to any side, so will lie on the line through the incenter and perpendicular to one side.

Angle bisectors

Reference the first attachment. We have elected to bisect the largest two angles of triangle ABC. In each case, we used these steps:

Centered at a vertex (B for example), draw an arc through the two sides of that angle (arc HI for example).Centered at the points of intersection with the sides, draw two intersecting arcs with the same radius (arcs HQ and IQ).Draw the angle bisector through this point of intersection and the original vertex (green line BQ).

After this process is repeated for another angle, the point of intersection of the two angle bisectors is the incenter (R).

Radius

Finding the radius requires finding the perpendicular distance to one side of the triangle. That is done by constructing a perpendicular to the side through the incenter.

Centered at the incenter (R), draw an arc that intersects one side in two places (arc UV).Centered at the points of intersection with the side, draw two intersecting arcs with the same radius (arcs UZ and VZ. Z is the unlabeled point at upper right).Draw perpendicular RZ intersecting the midpoint of UV at X.

Incircle

The inscribed circle is centered at R and has radius RX.

__

Circumscribed CircleSummary

The circumcenter (center of the circumscribed circle) is located at the coincidence of the bisectors of the sides of the triangle. The radius is the distance from the circumcenter to any vertex.

Perpendicular bisector

Reference the second attachment. We have elected to bisect the longest and shortest of the triangle's sides. The purpose of this choice is to make the perpendicular bisectors intersect at a large angle, so the point is as accurately located as possible.

Choose one side of the triangle and set the radius to more than half its length.Using that radius, draw intersecting arcs using each end of the side as a center (side AB and arcs FG, for example).Draw the perpendicular bisector through the points where the arcs intersect (line FG).

Repeat this process for another side (BC to create bisector JK). The intersection of the two bisectors (L) is the circumcenter.

Circumcircle

The circumscribed circle is centered at L and has radius LA.

__

Additional comments

In general, arcs that are required to intersect each other will be drawn with the same radius. An arc that is required to intersect two lines, or one line in two places, may have any convenient radius.

As with any geometric construction, the tools required are a marking tool, a compass, and a straightedge. Usually, the preferred marking tool is a sharp pencil.

If the triangle is obtuse, the circumcenter will be outside the triangle (adjacent to the long side). If the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse.

Salah is building a brick walkway around his garden, which is 17 feet wide and 40 feet long. he wants the walkway to be 18 inches wide on all sides. if the bricks are 6 inches wide and 8 inches long, what is the minimum number of bricks Salah will have to buy?

Answers

The minimum number of bricks Salah will have to buy is 4050 bricks

How to find the minimum number of bricks Salah will have to buy?

Given that the

width of the garden is w = 17 feet and length l = 40 feet. Also, the walkway iis 18 feet wide.

So, the length of walkway plus garden, L = 40 ft + 18 ft = 58 ft. The width of walkway plus garden, W = 17 ft + 18 ft = 35 ft.

The area of the walkway

We now need to find the area of the walkway.

Area of walkway, A" = area of walkway plus garden - area of garden

= LW - lw

= 58 ft × 35 ft - 40 ft × 17 ft

= 2030 ft² - 680 ft²

= 1350 ft²

Now, since each brick is 6 inches wide and 8 inches long, the area of each brick is A' = 6 in × 8 in  = 48 in²

So, the number of bricks required, n = area of walkway/area of brick

= 1350 ft²/48 in²

= 1350 × 144 in²/48 in²

= 194400 in²/48 in²

= 4050 bricks

So, the minimum number of bricks Salah will have to buy is 4050 bricks

Therefore, for the angle cos(∏/3), the angles that are similar to this angle will be expressed as Cos(2∏n + ∏/3) where n is any positive integer.

Then the other four angles will be 7∏/3, 13∏/3, 19∏/3, and 31∏/3. Also, the statement that all angles that have the same cosine will have the same sine is false. The sine of an angle is simply equal to the cosine of the complementary angle.

Find the missing side. Round your answer to the nearest tenth.
What are the steps to finding missing sides

Answers

Answer:

23.6

Step-by-step explanation:

→ Identify length not given

Opposite

→ Find a formula without opposite

Cos = Adjacent ÷ Hypotenuse

→ Rearrange

Adjacent = Cos × Hypotenuse

→ Substitute

cos 38 × 30 = 23.6

Answer:

[tex]x = 23.6[/tex]

Step-by-step explanation:

To find the missing side of a right-angled triangle, first look at the given angle, and notice its relationships with the given and required sides.

In this case:

• The side adjacent to the given 38° angle is [tex]x[/tex] (required).

• The hypotenuse is 30 units.

The trigonometric ratio that relates the adjacent side and hypotenuse of a triangle is cosine (cos), where:

[tex]\boxed{cos \space\ \theta = \frac{adjacent}{hypotenuse}}[/tex].

Substituting into the formula:

[tex]cos (38^{\circ}) = \frac{x}{30}[/tex]

⇒ [tex]x = cos(38^{\circ}) \times 30[/tex]

⇒ [tex]x = 23.6[/tex]
