Identify the factors of 15ab + 35a − 6b − 14.

Ilia_Sergeevich [38]

Answer:

(5a-3)(3b+7)

Step-by-step explanation:

Identify the factors of 15ab + 35a − 6b − 14

Given Data

15ab + 35a − 6b − 14

We have expression

15ab + 35a − 6b − 14------------

5a(3b-7)-3(2b+7)

Hence the factors are

(5a-3)(3b+7)

WXZY is a quadrilateral with W located at (-5, 2) and X is located at (3, 0). What must be the slope of ZY in order for WXYZ to

Verdich [7]

Answer: The answer is $-\dfrac{1}{4}.$

Step-by-step explanation: Given that WXZY is a quadrilateral with W located at (-5, 2) and X is located at (3, 0). We need to find the slope of ZY for which the quadrilateral WXZY is a parallelogram.

We know that the opposite sides of a parallelogram are parallel to each other. So, in the attached figure, we must have WX parallel to ZY. And for that, slope of WX = slope of ZY.

Slope of WX is given by

$m=\dfrac{0-2}{3-(-5)}=\dfrac{-2}{8}=-\dfrac{1}{4}.$

Thus, the slope of ZY must be $-\dfrac{1}{2}.$

Maria invests $6,154 in a savings account with a fixed annual interest rate of 8% compounded continuously. What will the account

VladimirAG [237]

Answer:

$13,695.98

Step-by-step explanation:

Continuously compounded interest formula:

$A = Pe^{rt}$

where

A = future value

P = principal (present value of amount invested)

e = mathematical constant, the base of natural logarithms

r = interest rate

t = time in years

We have: P = 6154; r = 8% = 0.08; t = 10

$A = 6154e^{0.08 \times 10}$

$A = 6154e^{0.8}$

$A = 6154 \times 2.2255$

$A = 13695.98$

Answer: $13,695.98

How long is the arc intersected by a central angle of startfraction pi over 2 endfraction radians in a circle with a radius of 4

Nimfa-mama [501]

7.1 cm long is the arc intersected by a central angle .

What is length of an arc?

The arc length of a circle can be calculated with the radius and central angle using the arc length formula.
Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ is in degree.

Given,

Central angle = π / 2

radius = 4.5 cm

we apply formula of length of arc.

length of the arc = angle × radius

= (π/2) × (4.5 cm)

Now put value of π = 3.14

length of the arc = (3.14 / 2) × (4.5) cm

= 7.065 cm ≈ 7.1 cm

Therefore, 7.1 cm long is the arc intersected by a central angle .
