Which choice correctly explains why 4 × 100 = 400? Multiplying 4 by 100 increases the place value of the digit 4 by moving it two places to the left.

Multiplying 4 by 100 decreases the place value of the digit 4 by moving it two places to the right.

Multiplying 4 by 100 increases the place value of the digit 4 by moving it one place to the left.

Multiplying 4 by 100 decreases the place value of the digit 4 by moving it one place to the right.

the answer is 5636.7

x = -5

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
