What are the values of a and b?<br> a=<br> b=
Basile [38]

Answer:

The values of a and b are:

  • a = 2
  • b=4

Step-by-step explanation:

Given the exponential model

y=a\cdot \:b^x

Given the points

(0, 2) and (3, 128)

We know that the y-intercept of y=a\cdot \:b^x is (0, a).

so

a = 2

putting x = 3, y = 128 and a = 2

y=a\cdot \:b^x

128=2\cdot \:b^3

Switching sides

2b^3=128

\frac{2b^3}{2}=\frac{128}{2}

b^3=64

Taking the real value such as:

\mathrm{For\:}x^3=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt[3]{f\left(a\right)}

so

b=\sqrt[3]{64}

b=\sqrt[3]{4^3}

b=4

Therefore,

  • a = 2
  • b=4

Solve<br> x2 - 8x + 14 = 2x - 7
BabaBlast [244]

Answer:

x=7, x=3

Step-by-step explanation:

             x^{2} -8x+14=2x-7

x^{2} -8x-2x+14+7=0

            x^{2} -10x+21=0

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

x= \frac{-b\pm \sqrt{b^2-4ac}}{2a}

positive

x=\frac{-\left(-10\right)+\sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}

x=7

negative

x=\frac{-\left(-10\right)-\sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}

x=3
