If a1= 7 and r=3, find a4

9966 [12]

Answer:

a4 = 189

Step-by-step explanation:

Geometric sequence:

In a geometric sequence, the quotient r between consecutive terms is always the same.

The nth term of the sequence is given by:

$a_n = a_1*r^{n-1}$

In which $a_1$ is the first term.

In this question:

$a_1 = 7, r = 3$

The fourth term is:

$a_4 = 7*3^3 = 189$

a4 = 189

| Find the quadratic polynomial whose<br> Sum and products of zeros are 21/8 and 5/16

tatuchka [14]

Answer:

$16x^{2} -42x+5$

Step-by-step explanation:

Sum of its zeroes= $\alpha +\beta =\frac{21}{8} \\$

Product of its zeroes= $\alpha \beta$ = $\frac{5}{16}$

Formula to form a quadratic polynomial:

$p(x)=k[x^{2} -(\alpha +\beta )x+\alpha \beta ]$

p(x)= $k[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]$

p(x)= $16[x^{2} -(\frac{21}{8} )x+\frac{5}{16}]$

p(x)= $[16x^{2} -42x+5]$

The quadratic polyniomial is $16x^{2}-42x+5$

Brian is 1 meter 87 centimeters tall. Bonnie is 58 centimeters shorter than brian. Betina is 26 centimeters taller than bonnie.

Nady [450]

Answer:

1 meter 3 centimeters

Step-by-step explanation:

Brian: 1 meter 87 centimeters

Bonnie: 58 cm shorter than Brian.

So, we subtract 58cm from Brian's 1 meter 87 cm.

We get that bonnie is 1 meter 29 cm.

Now Betina is 26 cm shorter than bonnie, so we subtract 26cm from Bonnie's height.

We get 1 meter 3cm which is Betina's height.
