Answer:

4.018secs

Step-by-step explanation:

Given the height reached by the test rocket by the expression  

h(t) = -16t^2 +116t + 101 gives the

The rocket will reach the ground when h(t) = 0

Substitute h(t) = 0 into the expression

0 = -16t^2 +116t + 101

Multiply through by -1

16t^2 -116t - 101 = 0

Factorize using the general formula

t = 116±√(116)²-4(16)(-101)/4(16)

t = 116±√(13,456+6,464)/64

t = 116±√(19,920)/64

t = 116±141.138/64

t = 116+141.138/64

t = 257.138/64

t = 4.018secs

Hence it will take the rocket 4.018secs to reach the ground

The measure of the value of x is 55°.

We have,

Complementary angles are two angles that add up to 90 degrees.

Supplementary angles are two angles that add up to 180 degrees.

Now,

The ray intersects two other rays forming a right angle.

This means,

It is a complementary angle.

i.e

x + (x - 20) = 90

x + x - 20 = 90

2x = 90 + 20

2x = 110

x = 55°

Thus,

The measure of the value of x is 55°.

Answer:

x - 3 > 15 ;

x > 18

Step-by-step explanation:

Given a number, x

3 less than x ; x - 3

3 less than x is more than 15

The inequality expression becomes ;

x - 3 > 15

We can solve for X ;

x - 3 > 15

Add 3 to both sides ;

x - 3 + 3 > 15 + 3

x > 18

Answer:

B.8

Step-by-step explanation:

The degree of a polynomial refers to the term with the highest exponent.  Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5.  When you multiply

x3*x5 = x3+5 = x8.  

So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.

Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second.  So you'll have something like ax3 * bx5.  That will result in x3*x5=x8, so your product will have degree 8.

Answer:

Answer is  5  pounds of bananas

Step-by-step explanation:

Required milk:

Milk= 2 gallons

Milk cost per gallon=$0.75

so,

2*0.75

$ 1.5

total amount =$2.25

to  calculate bananas

$2.25-$1.5=$0.75

per pound cost of bananas =$0.15

$0.75/$0.15

5 pounds of bananas

Dona bought 5 pounds of banana and 2 gallons of milk for a total of $2.25.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound.

Let,The cost of one gallon of milk is 'x' dollars and the cost of one pound of banana is 'y' dollars.

Also given Donna bought two gallons of milk and some bananas for a total of $2.25.

Therefore, 2(0.75) + 0.15y = 2.25.

0.15y = 2.25 - 1.5.

0.15y = 0.75.

y = 0.75/0.15.

y = 5.

So, Dona bought 5 pounds of bananas.

Answer: 120 Pounds

Step-by-step explanation:

Given

The Sum of David and mike weight is 180 pounds

Suppose the weight of David is x and the weight of mike is y

So, [tex]x+y=180[/tex]

Also, subtracting David's weight from Mike's weight, we get half of Mike's weight

[tex]\Rightarrow y-x=\dfrac{y}{2}\\\Rightarrow 2x=y[/tex]

Put the value of x in the above equation, we get

[tex]\Rightarrow 1.5y=180\\\Rightarrow y=120\ pounds[/tex]

Answer:

No Possible Triangles

Step-by-step explanation:

DeltaMath answer

P = 312.50

t = 9

r = ?

P(t) = P(9) = 1250

P(t) = Pe^(rt)

P(t) = Pe^(rt)

1250 = (312.50)e^(9r)

1250/312.5 = e^(9r)

4 = e^(9r)

ln(4) = ln(e^(9r))

ln(4) = (9r)ln(e)

[cancel out the e with ln on right side]

ln(4) = (9r)

ln(4) /9 = r

0.15 = r

The compound interest is computed both on the principal and the interest year on year. The rate of the interest is 0.16 or 16%.

A savings account is a type of account where an individual can save money for future purposes.

Here we havethe following information;

Principal = $312.50

Time = 9 years

Amount =  $1250.

rate = ?

Using the formula;

A = P(1 + r/n)^nt

Where n =1

1250 = 312.50( 1 + r)^9

1250/312.50 = ( 1 + r)^9

4 = ( 1 + r)^9

1.16 = 1 + r

r = 1.16 -1

r = 0.16 or 16%
