Write the equation in standard form using integers y=4x+5

Taya2010 [7]3 years ago

Unsure of what y ou want!  y = 4x + 5 is already in slope-intercept form.  If you want "standard form," which looks like Ax + By + C = 0, then identify A, B and C from the given equation y=4x+5.    Rewrite this as -4x + 1y - 5 = 0, so that A=-4, B=1 and C= -5.  This is the eqn in standard form.

Radium-226 has a half-life of 1620 years. for a 150 gram sample, how many grams will remain after 200 years?
VashaNatasha [74]
Ah, yes

if you start with P amount of something and the half life is h units (in years) and the time elapsed is t (in years) then the amount left is A

the equation is
A=P(\frac{1}{2})^\frac{t}{h}


so
given
h=1620
P=150
t=200
so
A=150(\frac{1}{2})^\frac{200}{1620}
A=150(\frac{1}{2})^\frac{10}{81}
use your calculator
A≈137.69781917515g
about 138grams left

\\h'(t)=(-4.9t^{2}+34.3t+1)'=-9.8t+34.3
\\h'(t)=0
\\-9.8t+34.3=0
\\
\\t= \frac{34.3}{9.8} =3.5
\\
\\h_{max}=h(3.5)=-4.9\times3.5^{2}+34.3\times3.5+1=61.025

The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.

65% of the 800 students at North High School ride the
jonny [76]

Answer:

520 out of 800 students ride the bus

Step-by-step explanation:

Given

Proportion = 65\%

Students = 800

Required

Determine the number of students that\ ride\ the\ bus

To do this, we simply multiply the proportion by the total number of students.

i.e.

Bus = Proportion * Students

Bus = 65\% * 800

Express the percentage as decimal

Bus = 0.65* 800

Bus = 520

Which of the following are solutions to the equation below?
sladkih [1.3K]

Answer:

\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}

                  x=3,\:x=-\frac{1}{2}

Step-by-step explanation:

considering the equation

2x^2\:-\:4x\:-\:3\:=\:x

solving

2x^2\:-\:4x\:-\:3\:=\:x

2x^2-4x-3-x=x-x

2x^2-5x-3=0

\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}

x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

\mathrm{For\:}\quad a=2,\:b=-5,\:c=-3:\quad x_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}

solving

x=\frac{-\left(-5\right)+\sqrt{\left(-5\right)^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}

x=\frac{5+\sqrt{\left(-5\right)^2+4\cdot \:2\cdot \:3}}{2\cdot \:2}

x=\frac{5+\sqrt{49}}{2\cdot \:2}

x=\frac{5+7}{4}

x=3

also solving

x=\frac{-\left(-5\right)-\sqrt{\left(-5\right)^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}

x=\frac{5-\sqrt{\left(-5\right)^2+4\cdot \:2\cdot \:3}}{2\cdot \:2}

x=\frac{5-\sqrt{49}}{4}

x=-\frac{2}{4}

x=-\frac{1}{2}

Therefore,

                 \mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}

                  x=3,\:x=-\frac{1}{2}
