Factor 20x2 + 25x – 12x – 15 by grouping. 1. Group terms with common factors. 2. Factor the GCF from each group. 3. Write the po

RUDIKE [14]

Step 1:

 (((22•5x2) + 25x) - 12x) - 15)))


The first term is, 20x2 its coefficient is 20 .
The middle term is, +13x its coefficient is 13 .
The last term, "the constant", is -15


step 2 above, -12 and 25
 20x2 - 12x + 25x - 15

Step-4 : Add up the first 2 terms, pulling out like factors :
 4x • (5x-3)
 Add up the last 2 terms, pulling out common factors :
 5 • (5x-3)
Step-5 : Add up the four terms of step 4 :
 (4x+5) • (5x-3)
 Which is the desired factorizationFinal result : (5x - 3) • (4x + 5)

Question 11 Find the value of y. X+ 13 45° No links please! Thanks for the help!

9966 [12]

Answer:

First option: $13 \sqrt{2}$

Step-by-step explanation:

$cosθ = \frac{adj}{hyp}$

$cos45° = \frac{13}{y}$

Multiply both sides by y:

$y(cos45°) = 13$

$y ( \frac{ \sqrt{2} }{2} ) = 13$

$y = 13 \div \frac{ \sqrt{2} }{2}$

$y = 13 \times \frac{2}{ \sqrt{2} }$

$y = \frac{26}{ \sqrt{2} } ( \frac{ \sqrt{2} }{ \sqrt{2} } )$

$y = \frac{26 \sqrt{2} }{2}$

$y = 13 \sqrt{2}$

The letters r and Θ represent polar coordinates. perform the following.

nexus9112 [7]

Answer:

$\boxed{(x - \frac{1 }{ 2})^{2} + y^{2} = \frac{21 }{ 4}}\\$

Step-by-step explanation:

$r = \frac{5}{r - cos\theta}\\r^{2} - rcos\theta = 5\\\\$

$\text{Use the relationships}\\r^{2} = x^{2} + y^{2}; cos\theta = \frac{ x}{r }\\$

$\begin{array}{ll}x^{2} + y^{2} - r(\frac{x }{r }) = 5 & \text{Made the substitutions } \\x^{2} + y^{2} - x = 5 & \text{Simplified } \\x^{2} -x + y^{2} = 5 & \text{Rearranged } \\x^{2} -x + \frac{1 }{ 4} + y^{2}= 5 + \frac{1 }{ 4} & \text{Completed the square } \\(x - \frac{1 }{ 2})^{2} + y^{2}= \frac{21 }{ 4} & \text{Wrote as sum of squares} \\\end{array}\\\\$
