Is this a right triangle?

Answer:

t = 2 s and t = 4 s

Step-by-step explanation:

A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by,

[tex]f (t) = -16t^2 + 96t[/tex]

We need to find in how many seconds will the rocket be at a height of 128 ft above the ground.

It means,

[tex]128= -16t^2 + 96t\\\\-16t^2+96t-128=0\\\\16(-t^2+6t-8)=0\\\\(-t^2+6t-8)=0\\\\-t^2+4t+2t-8=0\\\\t(-t+4)-2(-t+4)=0\\\\(t-2)=0\ and\ (-t+4)=0\\\\t=2\ and\ t=4[/tex]

So, it will be at a height of 128 feet at 2 second and 4 second.

Answer:

5 inches.

Step-by-step explanation: Take a length from the original (13.5) and divide it by the new length of that side (9) to get 1.5. Then take 7.5 and divide it by 1.5 to get 5 inches.

Answer:

5 in

Step-by-step explanation:

Similar figures have congruent corresponding angles and proportional corresponding sides.

Step-by-step explanation:

2a+26°+58°=180°

2a=180-26-58

2a=96

a=48

2*48+26=122

Given :

▪︎Measure of an angle in a parallelogram = 58°

▪︎Measure of the angle opposite this angle = (2x+26)°

We know that :

▪︎Opposite angles in a parallelogram are equal.

Which means :

[tex] =\tt 2a+ 26 = 58[/tex]

[tex] =\tt 2a = 58 - 26[/tex]

[tex] =\tt 2a= 32[/tex]

[tex] =\tt a = \frac{32}{2} [/tex]

[tex]\hookrightarrow\color{plum}\tt a = 16[/tex]

Thus, the value of a = 16

Let us now place 16 in the place of a and check whether or not we have found out the correct value of a:

[tex] =\tt 2 \times 16 + 26 = 58[/tex]

[tex] = \tt32 + 26 = 58[/tex]

[tex] =\tt 58 = 58[/tex]

Since the values in both the side match, we can conclude that we have found out the correct value of a.

▪︎Therefore, the value of a = 16

Answer:

Altitude

Step-by-step explanation:

An altitude of the triangle is the line segment from a vertex to the opposite side and perpendicular to the opposite side. The orthocenter will not always be inside the triangle. This is why the orthocenter is the point of concurrency of the lines containing the altitudes rather than just the altitudes.

Answer:

$42

Step-by-step explanation:

Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.

According to the given information:

Amount received by Amjit = Amount received by James + 28

So,

6x = 4x + 28

6x - 4x = 28

2x = 28

x = 28/2

x = 14

Amount of money received by Penny = 3x = 3*14 = $42

Answer:

94

Step-by-step explanation:

Y is the alternate interior angles of the degree that measures 94. This means that they are congruent so y=94

Answer: 13/24

Step-by-step explanation:

Since the teacher gives me 2/3 of the candy in the bag, and gives my friend 1/8 of it, the amount of candy that I got more than my friend will be gotten by subtracting 1/8 from 2/3. This will be:

= 2/3 - 1/8

The lowest common multiple of 3 and 8 is 24, therefore we can change the numerator if the fractions toma common base.

= 2/3 - 1/8

= 16/24 - 3/24

= 13/24

Answer: if you save $200 per month (with 2% interest compounded monthly) If you save $200 per month are are getting 2% interest on your money, you will have saved $2,400 and earned $26.16. The total result at the end of the year will be $2,426.16.

Answer:

162

Step-by-step explanation:

a=[tex]\frac{a+b}{2} h[/tex]

a=base and the base is 13 ft.

b= also means base which is 23 ft.

h= height which is 9 ft.

so 13+23 is 36

36/2 is 18

and 18 times 9 is 162

Answer:

the price of the shirt without discount is 75,000 pesos

Step-by-step explanation:

The computation of the price of the shirt without discount as follows:

There is a discount of 20%

And the person pays 60,000 pesos after considering the discount

So, the price without discount is

= 60,000 pesos ÷ 0.80

= 75,000 pesos

hence, the price of the shirt without discount is 75,000 pesos
