Trying to solve a exponential function question. Evaluate the function when t=5.

1 answer:

8 0

If t=5 then all you do is plug that into the function:
h(t)=175(1028)5
You would start by multiplying 1028 by 5 which leaves you with 5140, now plug that into the function.
h(t)=175(5140)
multiply 175 and 5140
h(t)=899500

What is the perimeter of the rectangle shown on the coordinate plane, to the nearest tenth of a unit?

Pavel [41]

see the attached figure to better understand the problem

Let

x------> the length side of a rectangle

y-------> the width side of a rectangle

we know that

the perimeter of a rectangle is equal to the formula

$P=2x+2y$

In this problem

$AB=DC=x\\AD=BC=y$

Step 1

Find the distance AB

$A(-6,4)\\B(4,2)$

we know that

the distance's formula between two points is equal to

$d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}$

substitute the values

$dAB=\sqrt{(2-4)^{2} +(4+6)^{2}}$

$dAB=\sqrt{(-2)^{2} +(10)^{2}}$

$dAB=\sqrt{104}\ units=10.2\ units$

Step 2

Find the distance BC

$B(4,2)\\C(3,-3)$

we know that

the distance's formula between two points is equal to

$d=\sqrt{(y2-y1)^{2} +(x2-x1)^{2}}$

substitute the values

$dBC=\sqrt{(-3-2)^{2} +(3-4)^{2}}$

$dBC=\sqrt{(-5)^{2} +(-1)^{2}}$

$dBC=\sqrt{26}\ units=5.1\ units$

Step 3

Find the perimeter

we know that

the perimeter of a rectangle is equal to the formula

$P=2x+2y$

$P=2AB+2BC$

substitute the values of the distance in the formula

$P=2*10.2+2*5.1=30.6\ units$

therefore

the answer is

The perimeter of the rectangle is equal to $30.6\ units$

Care este cel mai mic număr dintre 95.999,96.959,99.595 și 99.995 la care cifra unităților de mii este 5

Triss [41]

Răspuns:

95.999

Explicație pas cu pas:

Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5

95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă

96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă

99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci

99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.

Folosind cunoștințele despre linia numerică:

95.999 <96.959 <99.595 <99.995
