Substitute x with (-2) and y with (-4) Simplify: 5(41 - x) + {-7(y + x)} =

kkurt [141]

Answer:

$257$

Step-by-step explanation:

We want to evaluate:

$5(41 - x) + ( - 7(y + x)$

for x=-2 and y=-4.

We substitute to get:

$5(41 - - 2) + ( - 7( - 4 + - 2)$

We now simplify to get:

$5(41 + 2) - 7( - 6)$

$5 \times 43 + 42$

$215 + 42 = 257$

The graph of a sinusoidal function has a maximum point at (0,10) and then intersects its midline at (pi/4,4). Write the formula

Masja [62]

Answer: y = 6 cos (2x) + 4

Step-by-step explanation:

A cosine function is expressed as: y = A cos (Bx - C) + D where

amplitude (A) is the distance from the midline to the max/min.
B = 2π/P where P is the period
C/B is the phase shift
D is the center line (aka midline)

A = Max - Midline

= 10 - 4

= 6

The max to the midpoint is π/4

⇒ 1/4 P = π/4

⇒ P = π

B = 2π/P

= 2π/π

= 2

C = 0 because there is no phase shift

D = 4 (given)

Input A = 6, B = 2, C = 0, and D = 4 into the cosine function:

y = 2 cos (2x - 0) + 4

What fraction of the whole is 3%4 × 2/3

Alex777 [14]

Answer:

The given operation represents half the whole

Step-by-step explanation:

Fractions

They represent rational numbers of the form

$\displaystyle \frac{a}{b}$

where a and b are integer numbers and b is not zero

Fractions can also be used as ratios to compare quantities. For example, if a>b, then the fraction a/b is greater than 1. In the case of a<b, it's interpreted as parts of a whole.

The fraction

$\displaystyle \frac{2}{5}$

means something has 2 of each 5 parts of the whole.

The question requires to find the product of

$\displaystyle \frac{3}{4}\times \frac{2}{3}$

$\displaystyle \frac{2}{4}=\frac{1}{2}$

Thus, the given operation represents half the whole
