Answer:

The total cost would be 4.25 and the the price with 4 toppings would be 9.25.

Step-by-step explanation:

If you multiply 4x 1.25 you'll get five... Then you add that to you original price of 4.25 and the answer would be 9.25

Answer:

y=1.25x+3, $8.00

Step-by-step explanation:

3 is the variable. A cup of frozen yogurt will always be a set price of $3.00. The toppings are the variable, which will depend on how many the customer adds.

Therefore, the equation would be y=1.25x+3

x being the number of toppings added

If the customer orders one cup of ice cream with 4 toppings, the equation would look like:

y=(1.25*4)+3

y=(5)+3 = $8.00 for a four topping cup of frozen yogurt

Answer:

The length of the radius is 3cm.

Step-by-step explanation:

Given that a circle is inscribed in a square. The side of the circle touches the side of the square which is the diameter. So the diameter of circle is 6cm, in order to find it's radius, you have to duvide it by 2 :

$radius = diameter \div 2$

$radius = 6 \div 2$

$radius = 3cm$

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

Answer:

17 seconds

Step-by-step explanation:

Solution:-

The trajectory of a rocket launched is modeled by a parabolic path via a quadratic equation as follows:

$y = -16x^2 + 266x +102$

Where,

y: The height of the rocket from ground

x: The time taken since rocket launch

We are to determine the time ( x ) it takes for the rocket to hit the ground. This can be determined by setting the quantity ( y ) to zero as follows

$y = -16x^2 + 266x +102 = 0\\\\ -16x^2 + 266x +102 = 0$

solve the quadratic equation using quadratic formula as follows:

$x = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a} \\\\x = \frac{-266 +/- \sqrt{266^2 - 4*(-16)*(102)} }{2*(-16)} \\\\x = \frac{-266 +/- 278 }{-32} \\\\x = 8.3125 +/- 8.6875\\\\x = 17 , -0.375$
