The measures of the Angles of a triangle are shown in the figure below

Answers

Answer:

x = 22°

Step-by-step explanation:

The angles of a triangle add to 180°, so:

69 + (3x - 4) + (3x - 17) = 180

(3x - 4) + (3x - 17) = 111

6x - 21 = 111

6x = 132

x = 22

Answer:

22

Step-by-step explanation:

(3x - 4)° + (3x - 17)° + 69° = 180°

6x - 21 + 69 = 180

6x + 48 = 180 ⇒ x = 22

Allan has to make a delivery that is 1200 miles away. by law, he can only drive his truck for 20 hours without taking a break. What must allan's average speed be if he wants to make the delivery before he has to take a break?

Answers

Answer:

Step-by-step explanation:

60 average speed

The delivery must be completed by Allan before he needs to stop, thus his average pace must be at least 60 mph.

What is the average rate of change?

It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

If Allan has to make a delivery that is 1200 miles away and can only drive for 20 hours without taking a break,

we need to find his average speed to see if he can make the delivery before the 20-hour mark.

We can use the formula:

average speed = total distance / total time

We know the total distance is 1200 miles.

To find the total time, we need to know Allan's maximum driving time before taking a break. Let's assume that Allan will take a break after driving for 20 hours.

So, Allan's total time available to make the delivery is 20 hours.

Therefore,

average speed = total distance / total time

average speed = 1200 miles / 20 hours

average speed = 60 miles per hour

Allan's average speed must be at least 60 miles per hour to make the delivery before he has to take a break.

A ball falls from a window. It's height, as a function of time, is modleled by y= -4.9x2 +12. Which statement best describes the function? A. Not enough information is given to decide.

Answers

Answer:

Step-by-step explanation:

Given the the height covered by the ball modeled by the equation

y= -4.9x²+12

Since we are not told what to find, we can as well find the time taken by the ball to reach the ground.

The ball hits the ground when y = 0. Substitute y = 0 into the equation and calculate x;

y= -4.9x²+12

0 = -4.9x²+12

Subtract 12 from both sides

0-12 = -4.9x²+12-12

-12 = 4.9x²

x² = -12/4.9

x² = 2.448

x = √2.448

x = 1.57s

Hence we can say that the ball hits the ground after 1.57s.

if triangle ABC and DEF are congruent, what is the measure of angle E?

Answers

Answer: 83

Step-by-step explanation: Because the triangles are congruent, angle A is congruent to angle D, angle C is congruent to angle F, and angle E is congruent to angle B (CPCTC). Now because angle A and D are congruent they are both equal to 50. Using sum of angles in a triangle, you can find that measure of angle E is equal to 180- (47+50). That is 180-97=83.

Answer:

∠ E = 83°

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent.

Thus ∠ C = ∠ F = 47° and

∠ B = 180° - (50 + 47)° ← angle sum of Δ

∠ B = 180° - 97° = 83°

∠ B and ∠ E are corresponding angles, thus

∠ E = ∠ B = 83°

XY is tangent at P and CP is radius

[tex] \therefore CP\perp XP\\(\because tangent\: is \: perpendicular \: to\: radius) \\\\

\therefore m\angle CPX = 90\degree \\[/tex]

4.

Radius of the circle = diameter /2 = 13/2 = 6.5.cm

5.

For BD to be be tangent to the circle with center C, BD should make right angle with radius CB.

[tex] AD^2 [/tex] should be equal to the sum of the squares BD and AB.

Let us work it out:

[tex] AD^2 = 7^2 = 49....(1)\\

AB^2 + BD^2 = 5^2 +5^2 \\

AB^2 + BD^2 = 25 + 25 \\

AB^2 + BD^2 = 50....(2) \\[/tex]

From equations (1) & (2), it is obvious that:

[tex] AD^2 \neq AB^2 + BD^2[/tex]

So, BD is not tangent to the[tex] \odot\: C. [/tex]

6.

Tangents drawn from an external point to a circle are congruent.

In circle with center C, BA and BD are tangents drawn from external point B.

Therefore,

BA = BD

x = 4

7.

In circle with center C, BA and BD are tangents drawn from external point B.

Therefore,

BD = BA (tangents drawn from external point to a circle)

x = 2

In circle with center C, BA and BD are tangents drawn from external point B.

Therefore,

7 divided by 24 = 4 so it gets reduced to 1 and then 1/4

The solution is: 1/4  is the simplified form of the fraction 7/28.

Here, we have,

given that,

the fraction is: 7/28

now, we divide each fraction numerator and denominator by a common divisor of them,

here, we know that,

7 * 1 = 7

7*4 = 28

so, the gcf of 7 and 28 = 7

we divide each fraction numerator and denominator by a common divisor 7,

we will get:

7/28 = 1/4

7 divided by 28 = 4 so it gets reduced to 1 and then 1/4.

Hence, The solution is: 1/4  is the simplified form of the fraction 7/28.

Determine f(-2/3) for the function f(x)=3x²+2x+1​

Answer:

Step-by-step explanation:

To evaluate, substitute x = - [tex]\frac{2}{3}[/tex] into f(x), that is

f(- [tex]\frac{2}{3}[/tex] )

= 3(- [tex]\frac{2}{3}[/tex] )² + 2(- [tex]\frac{2}{3}[/tex] ) + 1

= 3([tex]\frac{4}{9}[/tex] ) - [tex]\frac{4}{3}[/tex] + 1

= [tex]\frac{4}{3}[/tex] - [tex]\frac{4}{3}[/tex] + 1

= 0 + 1

= 1

Answer:

1

Step-by-step explanation:

f(x) = 3x² + 2x + 1

f(-2/3) = 3x² + 2x +1

f(-2/3) = 3(-2/3)² + 2(-2/3) + 1          

Substitute the value in for all the x's

f(-2/3) = 3(4/9) + 2(-2/3) + 1

f(-2/3) = 12/9 + (-4/3) + 1

f(-2/3) = 4/3 + (-4/3) + 1                

Subtracting 4/3 by (-4/3) gets you 0 so I didn't write it down.

f(-2/3) = 1

So, the answer I got is 1
