Does anyone know this?! Pls help

Mathematics
1 answer:
Verdich [7]3 years ago
8 0

Answer:

Step-by-step explanation:

we are given the angles of XYR = 40, ZXY = 130, and SRY = 40 degrees.

angle ZXY is half of angle ZAY, so angle ZXY is 65 degrees.

imagine a line XA (not on the diagram). then ZXA is 32.5 degrees since it is half of YXZ. Angle XZA and ZXA are equal, so XZA is 32.5 degrees. RZA = XZA + RZX = 32.5 + 40 degrees (assuming the upper left stated degree belongs to angle XZA), or simply RZA is 72.5 degrees.

since ZRA = RZA, then ZRA is 72.5 degrees. since angle ZRS = SRY + ZRA, finally ZRA = 40 + 72.5 degrees or simply, ZRS = 112.5 degrees. which visually is blantantly wrong as it appears to be less than 90 degrees.

In △ABC, m∠ACB=90°, m∠ACD=60°, <br> CD<br> is the altitude to <br> AB<br> , and BD = 5 cm. Find AD.
LUCKY_DIMON [66]

Answer:

5cm

Step-by-step explanation:

Find the diagram attached.

From ΔBCD, ∠BCD = 90-∠ACD

∠BCD = 90-60

∠BCD = 30°

Also tan60 = CD/BD

tan 60 = CD/5

CD = 5tan60

CD = 5√3 cm

Similarly from ΔACD, tan30 = CD/AD

tan30 = 5√3/AD

AD = 5√3/tan30

AD =  5√3/(1/√3)

AD = 5√3 * √3/1

AD = 5 cm

Hence the length of side AD is 5cm

Determine the annual percentage rate (APR) for a tax refund anticipation loan based on the following information. (Round to the
loris [4]

Answer:

The correct answer is D. 500%

Step-by-step explanation:

Amount of Loan = $985

Total fees paid = $135

Term of loan = 10 days

  • First divide the amount of loan by total fees paid :

=\frac{985}{135}\\\\=0.137

  • Now, multiply the result by 365 :

= 0.137 × 365

=  50.03

  • Divide the result obtained by term of loan that is 10 days :

=\frac{50.03}{10}\\\\=5.003

  • Now, multiply this by 100 to get the final APR :

= 5.003 × 100

= 500%

Hence, The correct answer is D. 500%

A data set contains an independent and a dependent variable. Which must be true of the data set if a linear function can be
Rom4ik [11]

When we have dependent and independent variables we will have a linear relationship.

Let x be the independent variable and y be the dependent variable.

To write the  relationship we will have :

y = kx + c

Where k and c are constants.

In the case of a line the constant k is the gradient.

A multiplicative change is a log form and it is given by :

Y = Ck^x

The relationship is not linear but exponential.

The correct answer is thus :

Additive rate of change.
