Find the acute angle formed by line 2y=x+1

givi [52]

Answer:

26.57°

Step-by-step explanation:

$2y = x + 1 \\ y = \frac{1}{2} x + 1 \\ equating \: it \: with \\ y = mx + b \\ slope \: m = \frac{1}{2} \\ \because \: \tan \theta = m \\ \therefore \: \tan \theta = \frac{1}{2} = 0.5 \\ \therefore \: \theta = {tan}^{ - 1} (0.5) \\\therefore \: \theta = {tan}^{ - 1} ( \tan \: 26.565051177 \degree) \: \\ \\ \huge \red{ \boxed{\therefore \: \theta = 26.57 \degree}}$

A family uses 12,986. 64 Swiss francs per year to pay a mortgage that requires US dollars. Approximately how much, in US dollars

lukranit [14]

Unit conversion is a way of converting some common units into another without changing their real value. The amount that is paid by the family in mortgage per month is equal to $1200.

<h3>What is Units conversion?</h3>

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

As it is given to us that the family uses 12,986.64 Swiss francs per year to pay a mortgage. Therefore, the amount that is paid by the family in mortgage per month can be written as,

$\text{Mortgage for a month} = \dfrac{\text{Mortgage of the family for a complete year}}{\text{Number of Months}}\\\\\\\text{Mortgage for a month} = \dfrac{\rm 12,986.64\ Swiss\ francs}{12} = 1082.22\rm \ Swiss\ francs$

Thus, the family needs to pay 1082.22 swiss francs every month in the mortgage.

Now, it is mentioned in the problem that 1 Swiss franc = 1.11 US dollars, therefore, 1082.22 swiss francs when converted to US dollars will be equal to,

$\rm 1\ Swiss\ francs = \$1.11 \\\\1082.22\ Swiss\ francs = 1082.22 \times 1.11 = \$1,201.26 \approx \$1,200$

Hence, the amount that is paid by the family in mortgage per month is equal to $1200.

How do I solve this quadratic equation and find the possible values of k?

Natali [406]

Two equal roots means a discriminant of zero.

(k + 2)x² + 4k = (4k + 2) x

(k + 2)x²- 2 (2k + 1) x + 4k = 0

When we have an even linear term it's easier to generate 1/4 of the usual discrimant,

0 = d/4 = (b/2)^2 - ac = (2k + 1)² - 4k(k+2) = 4k² + 4k + 1 - 4k² - 8k = -4k + 1

4k=1

k=1/4

Answer: k=1/4

Check:

(k + 2)x² + 4k = (4k + 2) x

(9/4)x² - 3x + 1 = 0

9x² - 12x + 4 = 0

(3x - 2)² = 0

Geometry Find the area of the Triangle.

Alex17521 [72]

Answer:

<h2>answer: 390</h2>

Step-by-step explanation:

To find area for triangles you do

base × height ÷ by 2 So... 30 × 26 = 780

780 ÷ 2 = 390 so the area of this triangle is 390
