What is the in standard form 3(2a)+7(-4b)+3•c•5

Please help, will make brainliest

Goshia [24]

Answer/Step-by-step explanation:

1. Sin A = opp/hyp

Opp = 3

Hyp = 5

$sin(A) = \frac{3}{5}$ (substitution)

$sin(A) = 0.6$

2. Sin B = opp/hyp

Opp = 4

Hyp = 5

$sin(B) = \frac{4}{5}$ (substitution)

$sin(B) = 0.8$

3. Cos Q = adjacent/hypotenuse

Adjacent = 12

Hypotenuse = 13

$cos(Q) = \frac{12}{13}$ (substitution)

$cos(Q) = 0.9231$ (4 decimal places)

4. Cos S = adjacent/hypotenuse

Adjacent = 5

Hypotenuse = 13

$cos(S) = \frac{5}{13}$ (substitution)

$cos(S) = 0.3846$ (4 decimal places)

Hello!

<h2>Answer:</h2>

$\boxed{ \bf The~degree~of~the~polynomial~is~B.~5}$

___________________________________________

<h2>Explanation: </h2>

The term with the greatest exponent determines the degree of the polynomial.

Let's list all the terms:

$6x^{5}$

-4x²
2x²
-3
x

Out of all of these terms, the first one has the greatest exponent (5).

Sophia expects the number of cows, C C, on her farm t t years from now to be modeled by the function C ( t ) = 3 0 ( 2 ) C(t)=30

topjm [15]

Answer:

The expression is given as:

$H(t)=C(t)\times F(t)=240\times 3^t$ .

Step-by-step explanation:

Sophia expects the number of cows, C, on her farm t years from now to be modeled by the function:

$C( t ) = 30\times (2)^t$

Additionally, she expects the supply of hay, F, in tons, that her crops can provide for each cow t years from now to be modeled by the function

$F( t ) =8\times (1.5)^t$

Let H be the total yearly amount of hay produced in Sophia's farm (in tons) t years from now.

Total amount of Hay produced in sophia's farm= Number of cows in farm×Amount of hay required for each cow.

i.e. H(t)=C(t)×F(t)

$H(t)=30\times 8\times (2)^t\times (1.5)^t$

and we know that $a^x\times b^x=(a\times b)^x=(ab)^x$

Hence, $H(t)=240\times (2\times 1.5)^t\\\\H(t)=240\times 3^t$ .

Hence, the hay produced on Sophia's farm is used exclusively to feed her cows i.e. we need to write the formula of H ( t ) in terms of C(t) and F (t) is:

$H(t)=C(t)\times F(t)=240\times 3^t$ .
