Answer:

33 and 34

Step-by-step explanation:

Let the integers be x and x+1 respectively.

4x = 3(x+1) + 30

x = 33

therefore, the integers are 33 and 34

This is a question on forming and solving algebraic equations. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

EastWind [94]

Answer:

Vertex (-2.5,-300)

Step-by-step explanation:

We are given with h(t)=-16 t^2 +80 t.  We are asked to find the vertex.

X-coordinate of vertex =\frac{-b}{2a}

Where 'a' is coefficient of t^{2} term

'b' is coefficient of 't' term.

From given function, a= -16

b=80

So,

x-coordinate of vertex =\frac{-80}{2(-16)}

                                =-2.5

y-coordinate of vertex =-16(-2.5)^{2} +80(-2.5)

Simplify it,

            =-100 -200

           = -300

So, vertex is at (-2.5, -300).

Viktor [21]

Answer:

1500+337.50 = $1,837.5

Step-by-step explanation:

You want to calculate the interest on $1500 at 4.5% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

<em> I = P x r x t</em>

Where:

P is the principal amount, $1500.00.

r is the interest rate, 4.5% per year, or in decimal form, 4.5/100=0.045.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1500 × 0.045 × 5 to get that:

The interest is: $337.50
