Given h(t)=-2(t+5)^2+4, find h(-8) -334 -14 -45 -445

1 answer:

6 0

Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.

h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.

h(-8) = -2[9] + 4, multiply -2 and 9.

h(-8) = [-18] + 4, add -18 and 4.

h(-8) = -14.

Use the given information to prove that RSU=TSV

RoseWind [281]

Answer:

Statement, Reason

Given segment RV = segment TU, Given

m∠R = m∠T, Given

Segment RS ≅ segment ST, Base angles theorem

ΔRSV ≅ ΔTSU, SAS rule of congruency

Segment SV ≅ segment SU, CPCTC

VU ≅ UV, Reflexive property

RU = RV + VU, TV = TU + UV, Addition of segments

RV + VU ≅ TU + UV, Addition property of equality

RU ≅ TV, Transitive property of addition

ΔRSU ≅ ΔTSV, SSS rule of congruency

Step-by-step explanation:

Where:

SAS- Side Angle Side

CPCTC -Congruent Parts of Congruent Triangles are Congruent

SSS -Side Side Side

A certain function has zeros 4, 6i, and 2+5i. What other zeros MUST this function have?

kotykmax [81]

I think the answer is -6i and 2-5i

If I remember correctly imaginary numbers must also have their conjugate as a zero as well

Hope this helps

Max has sticks of lengths 6,7,8 and 10 inches. He wants to make a right triangle for an art project. Which 3 sticks should he us

MrMuchimi

C since that's the only triangle where A^2+B^2=C^2 (36+64=100).
