PLSS HELP WILL MARK BRAINLIEST!

Mathematics
1 answer:
ANEK [815]3 years ago
6 0

Answer:

y = 5

Step-by-step explanation:

The triangle is an isosceles triangle, which means that it has two equal sides and two equal angles.

Therefore, angles B and C are both equal to 75°.

A triangle measures 180°.

75 + 75 + x = 180

150 + x = 180

x = 30°

Angle A has to equal 30°.

(4y + 10)° = 30

4y + 10 - 10 = 30 - 10

4y = 20

y = 5

Hope that helps.

What’s all input for f(x)=3
defon

Answer:

all inputs are equal to <u>3</u>

Step-by-step explanation:

f(x) = 3 \\  =  3 \times 1\\  = 3  \times  {x}^{0}  \\ anything \: raised \: to \: 0 \: is \: 1 \\

\\  substituting \: any \: value \\  \: of \: x \: in \: f(x) \\ f(3) = 3 \times  {3}^{0}  \\  = 3 \times 1 \\ =  3 \\

\\ similarly \: all \: values \: of \: x \: will \\ give \: 3

)

t

, half life of tablet is about

2

hours and after

t

=

3

hours , remaining drug on patient's system is

42.875

mg.

Step-by-step explanation: Initial drug

x

=

125

mg ; rate of decay

r

=

100

=

0.3

gm/hour

Exponential model:

y

=

)

t

=

125

(

1

−

)

t

=

t

Half life:

y

=

mg

∴

62.5

=

125

⋅

0.7

t

or

t

=

What is a developing nation?
SCORPION-xisa [38]

Answer:

C.) (I think you meant to put c here) State with little or no economy

Step-by-step explanation:

This one was very confusing because I was beginning to think the answer could possibly be D as well. However, based on background knowledge of many developing countries in the previous century and also the present, many nations are still classified as developing despite the states being into conflict. Therefore revealing the states don't have to be working together in order to build an economy in order to be classified as a developing nation.

Now without a doubt, I do recall that a developing nation has little to no economy. That statement surely is more accurate due to it providing a fact rather than a hypothesis.

Number 28 ignore the bubbled in answer
Ghella [55]

Answer:

y = -7x+34

Step-by-step explanation:

We have 2 points, so we can find the slope

m = (y2-y1)/(x2-x1)

    = (6--1)/(4-5)

    = (6+1)/(4-5)

     = 7/-1

    = -7

We can use point slope form to make an equation

y-y1 = m(x-x1)

y--1 = -7(x-5)

y+1 = -7(x-5)

Distribute

y+1 = -7x+35

Subtract 1 from each side

y+1-1 = -7x+35-1

y = -7x+34
